ABSTRACT: Due to the increased use of mobile devices with the high demand for applications such as video application, most companies have tended to pay attention to Mobile Ad hoc Networks. This type of network is characterized by multi-hop wireless networks where data packets are sent in a "store and forward" manner from the source to an arbitrary destination via intermediate nodes. The mobile nodes are connected by multi-routes routing as the nodes in this network not only serve as hosts but also as routers where data is routed to and from other nodes in the network and therefore the mobile node not only sends its data packets but also sends data packets of other mobile nodes. The network architecture changes dynamically, mainly because of Mobility of nodes, so we need routing protocols to establish the connection. Routing protocols are categorized into proactive routing protocols, reactive routing protocols and hybrid routing protocols.
So in this research, we has been studied Geographical Routing Protocol (GRP ), Optimized Link State Routing Protocol (OLSR) routing protocols which is one of proactive routing protocols and hybrid routing protocols respectively on the basis of Throughput, Delay and Load..etc and evaluated the performance in a large mobile ad hoc network and in a small mobile ad hoc network as well as for different video resolutions, the OPNET 14.5 network simulator was used to obtain research results. It was found that the GRP protocol performs better for a small number of nodes whether the video resolution is low or high while its performance decreases when the number of nodes increases in the network but the OLSR protocol improves when the number of nodes is increased.

Abstract: In view of the increasing use of mobile devices in addition to the high demand for the applications provided by these devices including video streaming, most companies have tended to pay attention to the mobile ad hoc networks and search for solutions to the problems and obstacles that hindered the process of sending video in this type of networks. One of the solutions discussed: Solutions at the level of video compression technology where many of the standards that were used in the process of video encoding and that provide good video quality by using a few bits in the coding process as provided us with acceptable bandwidth for the user and are flexible in handling with errors. These standards are: "H. 264/ MPEG-4 part 10".
There was also a solution at the level of routing during the transmission of video in real time over the mobile ad hoc networks so in this paper has been studied OLSR routing protocol that support the transmission of video on the basis of delay, network load and throughput and evaluated the performance by changing the model where the node is located (Node Placement Model) in a large network and in a small network as well as for different video resolutions.
Keywords: MANET, routing protocol, OLSR, video streaming, node placement models.

A Mobile Ad Hoc Network (MANET) is created when an independent mobile node network is connected dynamically via wireless links. MANET is a self-organizing network that does not rely on pre-existing infrastructure such as wired or wireless network routers. Mobile nodes in this network move randomly, thus, the topology is always changing. Routing protocols in MANET are critical in ensuring dependable and consistent connectivity between the mobile nodes. They conclude logically based on the interaction between mobile nodes in MANET routing and encourage them to choose the optimum path between source and destination. Routing protocols are classified as proactive, reactive, or hybrid. The focus of this project will be on Optimized Link State Routing (OLSR) protocol, a proactive routing technique. OLSR is known as the optimized variant of link state routing in which packets are sent throughout the network using the multipoint relay (MPR) mechanism. This article evaluates the performance of the OLSR routing protocol under condition of changing mobility speed and network density. The study's performance indicators are average packet throughput, packet delivery ratio (PDR), and average packet latency. Network Simulator 2 (NS-2) and an external patch UM-OLSR are used to simulate and evaluate the performance of such protocol. As a result of research, the approach of implementing the MPR mechanism are able to minimise redundant data transmission during the normal message broadcast. The MPRs enhance the link state protocols' traditional diffusion mechanism by selecting the right MPRs. Hence, the number of undesired broadcasts can be reduced and limited. Further research will focus on different scenario and environment using different mobility model.

Routing protocols have an important role in any Mobile Ad Hoc Network (MANET). Researchers have elaborated several routing protocols that possess different performance levels. In this paper we give a performance evaluation of AODV, DSR, DSDV, OLSR and DYMO routing protocols in Mobile Ad Hoc Networks (MANETS) to determine the best in different scenarios. We analyse these MANET routing protocols by using NS-2 simulator. We specify how the Number of Nodes parameter influences their performance. In this study, performance is calculated in terms of Packet Delivery Ratio, Average End to End Delay, Normalised Routing Load and Average Throughput.

In Today, user wants the wireless network anywhere. The wireless communication devices are transmitters, receivers and various smart antennas. These smart antennas may be any kind and the number of nodes can be fixed or mobile. The term node is referred to as nodes which can move arbitrarily in any direction. The wireless mobile nodes when collected at an instant are forming a temporary network without use of any re-existing network. The Ad-hoc routing protocols have number of types which are useful during the time of connectivity to form network. Routing protocols for mobile Ad-hoc networks have to face the challenge of changing the network topology by changing the number of mobile nodes. Scalability is an open issue in all routing protocols. In this review paper, there are observations of OLSR protocol regarding the scalability comparison of the Optimized Link State Routing (OLSR) by varying the number of nodes. The simulation is done by using OMNET++ by taking end to end delay, throughput and Packet delivery ratio as performance metrics.

Flying ad hoc network (FANET) is widely used in many military, commercial and civilian applications. Compared with mobile adhoc network (MANET) and vehicular ad hoc network (VANET), FANET holds unique characteristics such as high mobility, intermittent links and frequent topology changes, which cause a challenging task in the design of routing protocols. A novel adaptive software defined networking (SDN)-based routing framework for FANET called ASR-FANET is proposed in this article to solve the above challenges. The ASR-FANET framework is mainly composed of three important parts, which are the topology discovery mechanism, statistics gathering mechanism and route computation mechanism. In topology discovery mechanism, the periodic information about network topology is collected, including nodes and links. In statistics gathering mechanism, the status of the wireless network connection and flight statistics are collected. In route computation mechanism, the optimal path is calculated based on link costs. The performance of ASR-FANET framework is also has been evaluated by comprehensive simulations. The simulation results show that proposed framework is much better than other traditional protocols in packet delivery fraction, average end to end delay, normalized routing load, packet loss and throughput.

This chapter presents a multihop routing solution, called Hopefully Longest Jump First, specifically proposed for WSNs arranged in a linear topology and compares it to two simple approaches, named Single Hop and Limited Flooder. At the application level, we suppose that a Master Node, deployed at one side of the WSN, progressively queries each of the N Slave Nodes. On its turn, when queried, a Slave Node replies to the Master Node. The performance of the proposed routing schemes is evaluated and compared on the basis of experimental results involving a real indoor WSN composed of 11 Telos motes, representing 1 Master Node and 10 Slave Nodes. The WSN has been deployed inside ISMB Lab. The analysis is based on performance metrics such as end-to-end delay and end-to-end packet delivery success rate, also considering the impact of the distance between two adjacent nodes and thus the expected number of neighbors within a node radio coverage.

For next generation wireless networks, supporting quality of service (QoS) in multimedia application like
video, streaming and voice over IP is a necessary and critical requirement. Wireless Mesh Networking is
envisioned as a solution for next networks generation and a promising technology for supporting
multimedia application.
With decreasing the numbers of mesh clients, QoS will increase automatically. Several research are
focused to improve QoS in Wireless Mesh networks (WMNs), they try to improve a basics algorithm, like
routing protocols or one of example of canal access, but in moments it no sufficient to ensure a robust
solution to transport multimedia application over WMNs.
In this paper we propose an efficient routing algorithm for multimedia transmission in the mesh network
and an approach of QoS in the MAC layer for facilitated transport video over the network studied.

Mobile Ad-hoc Networks (MANETs) are independent systems that can work without the requirement for unified controls, pre-setup to the paths/routes or advance communication structures. The nodes/hubs of a MANET are independently controlled, which permit them to behave unreservedly in a randomized way inside the MANET. The hubs can leave their MANET and join different MANETs whenever the need arises. These attributes, in any case, may contrarily influence the performance of the routing conventions (or protocols) and the general topology of the systems. Along these lines, MANETs include uniquely planned routing conventions that responsively as well as proactively carry out the routing. This paper assesses and looks at the effectiveness (or performance) of five directing conventions which are AOMDV, DSDV, AODV, DSR and OLSR in a MANET domain. The research incorporates executing a simulating environment to look at the operation of the routing conventions dependent on the variable number of hubs. Three evaluation indices are utilized: Throughput (TH), Packet Delivery Ratio (PDR), and End-to-End delay (E2E). The assessment outcomes indicate that the AODV beats other conventions in the majority of the simulated scenarios.

In the design of mobile ad hoc networks, a challenging problem is how to route information reliably and efficiently from one node to another in moderate to high level of mobility. Due to mobility, limited residual energy of the node, selection of stable and durable path for the communication is the challenge. Also remaining queuing capacity is also affected on the packet loss. Many proposals have been addressed to this problem; however, few papers consider a proactive protocol like Optimized Link State Routing Protocol (OLSR) to better manage the energy consumption and link stability in routing path selection algorithms. In this paper, we explored modification to MPR selection and integrating appropriate routing metrics in the routing decision scheme to lessen effects of reason that lead to more packet loss. Our power-aware version of OLSR is proven by simulations in NS3 under a range of different mobile scenarios and network density. Significant performance gains are obtained in terms of packet loss ratio and MPR count for our modified OLSR version.

Black hole and Grey hole attack is most happening attacks in Mesh networks. Mesh networks means nonstatic networks with making loops of networks with the help of active hotspots. In Wireless networks all the communication between the nodes is happening wirelessly and the nodes are so much resource constraint that it is difficult to employ any security solutions of other ad hoc networks. So they are attacked by malicious nodes. In black hole attack the attacker windup all the information and dropped it. In black hole attack, the series of RREQ (route request) and RREP (route reply) follows the smallest way of networking communication. The fault node always transmit RREP message as it receives RREQ, while managing the receivers sequence number. By the help of fault node packets are dropped. Sometimes fault node is authorised and otherwise it is unauthorised. Black hole attack is type of routing attack and can bring harm to whole network. Grey hole attack is the kind of denial of service attack. In this attack, the router which is mesh behave just not well and a subset of packets are forward and handle by receiver but leave by others. The presences of these attackers are hard to detect in wireless networks because over the wireless link the packets are lost due to bad channel quality. This paper deals with the study of analysis of delay occurs by these attack in Wireless Mesh networks and its types and also discuss about previous study by which we get idea about attack occurs in networks and also study various techniques to detect and prevent network from black hole and grey hole attack. Then we discuss about their result by using simulator OPNET.

With the rapid development in mobile Wireless Sensor Networks (WSNs), it has become very essential to focus on the efficiency in performance of small sensing nodes operating in WSNs. While designing a routing protocol for mobile sensor nodes, the quality parameters like end-to-end delays and routing overhead are always considered. Moreover, the nodes in wirelessly connected mobile networks consume considerable power on routing more than other functionalities. Any modification in a standard routing protocol can also affect routing overhead, end-to-end delays, and energy consumption of nodes. In this paper a new hybrid routing protocol, named as State-Aware Link Maintenance Approach (SALMA), is introduced which is based on Dynamic Source Routing (DSR) and Optimized Link State Routing (OLSR) protocols. The work also focuses on the activeness of nodes in the network operations and defines three states of nodes, that is, white, gray, and black. The work concludes that the proposed protocol gives improvements in some quality of service metrics like lower delay than DSR, lower routing overhead than OLSR, and lesser energy consumption by the network nodes.

In an Optimized Link State Routing (OLSR)-based mobile wireless network,
optimizing the flooding of broadcast messages is a challenging task due to
nodeŠs mobility and bandwidth resource consumption. To complement ex-
isting solutions to this problem, the Multi-Point Relays (MPR) selection has
recently been advocated as a promising technique that has an additional fea-
ture of reducing the number of redundant re-transmission occurring in the
network. Here in this paper, continuous on the investigation of an existing
MPR-based solution, arguing that by considering a cost factor as an addi-
tional decision parameter in selecting the MPR nodes, the enhanced MPR
selection algorithm leads to less packet loss in the network. Simulation exper-
iments are presented to validate the stated goal, using the average packet loss
ratio as the performance metric.

Las redes inalámbricas con topología física de malla son redes de conmutación de paquetes que no manejan una estructura central inalámbrica fija. Como principal ventaja exhiben el brindar acceso inalámbrico desde cualquiera de sus nodos, operando a un mismo tiempo como clientes/repetidores, permitiendo extender la cobertura a mayores distancias que una topología de infraestructura. El estándar IEEE 802.11b,g,n de comunicaciones inalámbricas no contempla dentro de sus protocolos una comunicación full-duplex, por lo tanto es importante la caracterización del desempeño de los enlaces para estimar el decremento aceptable del servicio. Actualmente existen varias propuestas a nivel experimental y proveedores de nodos malla. mas no un estándar definido por lo que éste trabajo se centra en la tarea de la caracterización.

An important element of any routing protocol used for Wireless Mesh Networks (WMNs) is the link cost function used to represent the radio link characteristic. The majority of the routing protocols for WMNs attempt to accurately characterise the radio link quality by constructing the link cost function from the measurements obtained using active probing techniques which introduces overhead.

Mobile Ad hoc Network (MANET) is a collection of wireless mobile nodes that dynamically form a network temporarily without any support of central administration. Moreover, Every node in MANET moves arbitrarily making the multi-hop network topology to change randomly at unpredictable times. There are several familiar routing protocols like DSDV, AODV, DSR, etc… which have been proposed for providing communication among all the nodes in the network. This paper presents a performance comparison of proactive and reactive protocols DSDV, AODV and DSR based on metrics such as throughput, packet delivery ratio and average end-to-end delay by using the NS-2 simulator.

Wireless Mesh Networks (WMNs) adalah suatu jaringan nirkabel multi-hop dimana router mesh stasioner dapat mengi-rimkan trafik kepada router mesh yang lain atau klien dalam bentuk wireless backbone. Tujuannya adalah menawarkan pengguna suatu bentuk jaringan nirkable yang dapat dengan mudah berkomunikasi dan mempunyai mobilitas yang tinggi sekaligus memiliki kecepatan tinggi dan cangkupan jaringan yang luar. Diperlukan suatu disain arsitektur jaringan nirkable yang bisa mendukung tujuan tersebut, serta perlu adanya protocol routing yang effisien. Dalam tulisan ini arsitektur jarin-gan nirkable yang digunakan adalah Wireless Mesh Networks(WMNs) dengan protokol OLSR yang merupakan protocol routing proaktif. Protokol OLSR terbukti lebih efektif bila diterapkan pada mesh network bila dibandingkan dengan meng-gunakan protokol AODV. Heuristic diperlukan untuk meningkatkan protokol OLSR melalui adaptive refreshing time inter-val dan memperbaiki pemilihan MPR menunjukkan kinerja yang optimal dalam hal throughput jika dibandingkan dengan protokol OLSR asli. Akan tetapi terdapat kenaikan delay, maka diperlukan suatu analisa untuk meningkatkan protocol OLSR untuk meningkatkan efektivitas kinerja yang tidak mengakibatkan kenaikan delay dengan cara melakukan modifikasi pemilihan node MPR yang terdekat.

Several types of Routing Protocols for mobile ad hoc networks have been proposed recently for their application in various areas such as military, government and many other fields. In this paper, we have proposed a comparative study of various routing protocols for mobile ad-hoc networks particularly emphasizing on its security aspect. Furthermore, we have discussed the comparison among existing routing protocols for MANET. Main factor for comparison is routing methodologies and knowledge required to make routing decisions. The comparison is made on the basis of the following factors: integrity, confidentiality, authentication, nonrepudiation and availability. Analysis of the secured version of proposed routing method has been done on the basis of the five security requirements and the same has been shown in the comparison tables.

The routing protocols play an important role in Mobile Ad-Hoc Network (MANET) because of the dynamically change of its topology. Optimized Link State Routing (OLSR), unawareness of Quality of Service (QoS) and power-consumed protocol, is an example of a widely-used routing protocol in MANET. The Multi-Point Relays (MPR) selection algorithm is very crucial in OLSR. Therefore, firstly, we propose a heuristic method to select the best path based on two parameters; Bit Error Rate (BER) derived from the physical layer and Weighted Connectivity Index (CI) adopted from the network layer. This can be done via the cross-layer design scheme. This is anticipated to enhance the performance of OLSR, provide QoS guarantee and improve the power consumption. The performances of the proposed scheme are investigated by simulation of two types of traffics: CBR and VBR (MPEG-4), evaluated by metrics namely Throughput, Packet Delivery Ratio (PDR), Average End-to-End Delay, Control Overhead and Average Total Power Consumption.We compare our results with the typical OLSR and OLSR using only Weighted CI. It is obvious that our proposed scheme provides superior performances to the typical OLSR and OLSR using only Weighted CI, especially, at high traffic load.

Voice over Internet Protocol (VoIP) may provide good services through Vehicular ad hoc networks
(VANETs) platform by providing services to many application scenarios range from safety to comfort.
However, VANETs networks introduce many challenges for supporting voice with QoS requirements. In
this paper, our study is based on Inter-Vehicle voice streaming rely on multi-hop fashion. For this task, a
performance evaluation of various audio CODECs will be analyzed by mean of simulations.
Furthermore, we test the impact of network environment on QoS metrics. To achieve good results,
CODECs behaviour is tested by using mobility information obtained from vehicular traffic generator. The
mobility model is based on the real road maps of an urban environment. Focusing on inter-vehicular
voice traffic quality, we provide simulations results in terms of both user level (MOS) metrics and
network level (such as Losses). According to this performance evaluation, we show that G.723.1 CODEC
worked well in the urban VANET environment.

Mobile Ad-Hoc network is a collection of mobile nodes in communication without using infrastructure.
As the real-time applications used in today’s wireless network grow, we need some schemes to provide
more suitable service for them. We know that most of actual schemes do not perform well on traffic which
is not strictly CBR. Therefore, in this paper we have studied the impact, respectively, of mobility models
and the density of nodes on the performances (End-to-End Delay, Throughput and Packet Delivery ratio)
of routing protocol (Optimized Link State Routing) OLSR by using in the first a real-time VBR (MPEG-4)
and secondly the Constant Bit Rate (CBR) traffic. Finally we compare the performance on both cases.
Experimentally, we considered the three mobility models as follows Random Waypoint, Random
Direction and Mobgen Steady State. The experimental results illustrate that the behavior of OLSR change
according to the model and the used traffics.

The expansion in information technology and the need for large scale communication infrastructures has triggered the area of Wireless Sensor Networks (WSNs). Network is a collection of wireless nodes these are communicates with each other without using any offered infrastructure, access point or centralized administration. Wireless sensor networks may consist of hundreds or even up to thousands of small dense devices, equipped with sensors (e.g. acoustic, seismic or image), that form a wireless network. Each sensor node in the network collects information from its surroundings and sends it to a base station, either from source sensor node to destination sensor node, i.e. multi-hop, or directly to the base station. This paper presents performance comparison of four popular wireless sensor network routing protocols i.e. Dynamic Source Routing (DSR), Optimized Link State Routing (OLSR), Fisheye State Routing Protocol (FSR) and Location - Aided Routing (LAR) in variation of nodes and random waypoint mobility. We used well known network simulator QualNet 5.0 from scalable networks to evaluate the performance analysis of above protocols. The metrics used for performance analysis of End to End delay (s), Average Jitter (s), Power consumption in receive mode, transmit mode, idle mode and battery consumption.
