In this paper, we have analyzed the performance of multipath routing protocol with various mobility models for Mobile Ad Hoc Networks. The basic purpose of any multipath routing protocol is to overcome various problems occurs while data delivery through a single path routing protocol. For high acceptability of routing protocol, analysis of routing protocol in ad hoc network only with random way point mobility model is not sufficient. Here, we have considered Random waypoint, Random Direction and Probabilistic Random Walk mobility Model for proper analysis of AOMDV routing protocol. Results obtained show that with increasing node density, packet delivery ratio increases but with increasing node mobility Packet delivery ratio decreases.

Routing protocols are responsible for providing reliable communication between the source and destination nodes. The performance of these protocols in the ad hoc network family is influenced by several factors such as mobility model, traffic load, transmission range, and the number of mobile nodes which represents a great issue. Several simulation studies have explored routing protocol with performance parameters, but few relate to various protocols concerning routing and quality of service (QoS) metrics. This paper presents a simulation-based comparison of proactive, reactive, and multipath routing protocols in mobile adhoc networks (MANETs). Specifically, the performance of AODV, DSDV, and AOMDV protocols are evaluated and analyzed in the presence of varying the number of mobile nodes, pause time, and traffic connection numbers. Moreover, Routing and QoS performance metrics such as normalized routing load, routing packet, packet delivery ratio, packet drop, end-to-end delay, and throughput are measured to conduct a performance comparison between three routing protocols. Simulation results indicate that AODV outperforms the DSDV and AOMDV protocols in most of the metrics. AOMDV is better than DSDV in terms of end-to-end delay. DSDV provides lower throughput performance results. Network topology parameters have a slight impact on AODV performance.

n this paper, we have analyzed the effect of node
mobility on theperformance of AOMDV multipath routi
ng
protocol. This routing protocol in ad hoc network
has been analyzed with random way point mobility mo

er, we
have considered Random waypoint, Random Direction a
nd Probabilistic Random Walk mobility Model for
performance analysis of AOMDV protocol. The result
reveals that packet delivery ratio decreases with t

increasing node mobility forall mobility models. Al
so, average end-to-end delay is also vary with vary

node speed, initially upto 20 nodes in all mobility
models delay is minimum.

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.

MANET is a standalone system of mobile wireless nodes that move at any time within a changing topology. These mobile nodes are self-managed, perform the routing process, and flow data between them across multiple hops and independently of any central authority. The path from the source node to the target node is chosen based on several criteria called path selection criteria. Single-Path routing protocols store the best path for the target node in the source node routing table, while Multi-Path routing protocols store multiple paths for the target node in the source node routing table with the goal of having Alternate paths that can be used if the primary path used fails. In this research, we conducted a performance Evaluation of the Multi-path routing protocols in wireless mobile Ad-hoc networks AODMV, MDART, where the nodes move random movement in the RWP model, and the contract speed is changed for all performance parameters (throughput -Data Packets Dropped - Average End-to-End Delay - Packet Delivery Ratio/Fraction - Normalized Routing Load - Routing Overhead). The study showed that the performance of the AOMDV protocol is best for medium and slow speed in all measured parameters, while performance of MDART protocol is the worst for medium and slow speed, and that there is no effective routing protocol no matter how fast the nodes are.

One of the most important issues discussed in Wireless Sensor Networks (WSNs) is how to transfer information from nodes within the network to the base station and select the best possible route for transmission of this information, taking into account energy consumption for the network lifetime with maximum reliability and security. Hence, it would be useful to provide a suitable method that would have the features mentioned. This paper uses an Ad-hoc On-demand Multipath Distance Vector (AOMDV) as a routing protocol. This protocol has high energy consumption due to its multipath. However, it is a big challenge if it can reduce AOMDV energy consumption. Therefore, clustering operations for nodes are of high priority to determine the head of clusters which LEACH protocol and fuzzy logic and Particle Swarm Optimization (PSO) algorithm are used for this purpose. Simulation results represent 5% improvement in energy consumption in a WSN compared to AOMDV method.

Mobile communication plays an important role in disaster recovery management during emergency situations. It is helpful in situations where the system has less robust and less flexible fixed infrastructure. The Disaster recovery management systems require timely interaction and coordination in order to save lives and property. Energy consumption in heterogeneous network is a major issue , whether they operate within a base station infrastructure , fixed network or in a free-standing Mobile Ad Hoc Network (MANET). The lifetime of network will be improved by suitably reducing the requirement of power for connections. There is a challenge to provide Quality of Service (QoS) solutions to wired cum wireless domains and maintain end-to-end QoS in ad hoc network. In this paper we propose a new protocol Power Aware QoS Multipath Routing protocol (PAQMR) for disaster recovery network. This protocol is the enhanced protocol of Ad-Hoc On Demand Multipath Distance Vector protocol (AOMDV). This routing protocol is used to avoid the loop formation in network so that it reduces congestion in the channel. The Network Simulator (NS-2.34) tool is utilized to measure the performance of AODV, AOMDV and PAQMR protocols in hybrid environment. The metrics for the simulation are energy consumption, average end to end delay and packet delivery ratio by varying the traffic load and pause time in the network. The results shows that the proposed protocol minimize the power, delay, congestion and maximize the packet delivery ratio.

A Wireless Sensor Networks is a network formed with sensors that have characteristics to sensor an area to extract a specific metric, depending of the application. We would like to analyse the feasibility to use sensors in a coffee crop. In this work we are evaluating routing protocols using real dimensions and characteristics of a coffee crop. We evaluate, through simulation, AODV, DSDV and AOMDV and two variants known in this work as AODVMOD and AOMDVMOD with 802.15.4 MAC Protocol. For this comparison, we defined three performance metrics: Packet Delivery Ratio (PDR), End-to-End Delay and Average Energy Consumption. Simulation results show that AOMDVMOD overall, outperforms others routing protocols evaluated, showing that is possible to use WSN in a real coffee crop environment.

In Mobile Ad hoc Network (MANET) all the nodes are freely moves in the absence of without ant centralized coordination system. Due to that the attackers or malicious nodes are easily affected that kind of network and responsible for the routing misbehavior. The routing is network is mandatory to deliver data in between source and destination. In this research we work on security field in MANET and proposed
a novel security scheme against routing misbehavior through Black hole attack. The Ad hoc On demand Multipath Routing (AOMDV) protocol is consider for routing and also to improves the routing quality as compare to single path routing protocol. The attacker is affected all the possible paths that is selected by sender for sending data in network. The malicious nodes are forward optimistic reply at the time of routing by that their identification is also a complex procedure. The proposed Intrusion Detection System (IDS)
scheme is identified the attacker information through hop count mechanism. The routing information of actual data is reached to which intermediate node and the next hop information is exist at that node is confirm by IDS scheme. The black hole attacker node Identification (ID) is forward in network by that in future attacker is not participating in routing procedure. The proposed security scheme detects and provides the deterrence against routing misbehavior through malicious attack. Here we compare the routing performance of AOMDV, Attack and IDS scheme. The performance of normal multipath routing and proposed IDS scheme is almost equal. The attacker has degrades the whole routing performance but observed that in presence of attacker, routing misbehavior is completely block by the proposed IDS scheme and recovers 95 % of data as compare to normal routing.

In this paper, we have analyzed the effect of node mobility on theperformance of AOMDV multipath routing protocol. This routing protocol in ad hoc network has been analyzed with random way point mobility model only. This is not sufficient to evaluate the behavior of a routing protocol. Therefore, in this paper, we have considered Random waypoint, Random Direction and Probabilistic Random Walk mobility Model for performance analysis of AOMDV protocol. The result reveals that packet delivery ratio decreases with the increasing node mobility forall mobility models. Also, average end-to-end delay is also vary with varying node speed, initially upto 20 nodes in all mobility models delay is minimum.

The most important experiences we discovered from several disasters are that cellular networks were vulnerable, and the loss of the communication system may have a catastrophic consequence. Mobile ad-hoc networks (MANETs) play a significant role in the construction of campus, resident, battlefield and search/rescue region. MANET is an appropriate network for supporting a communication where is no permanent infrastructure. MANET is an effective network that uses to establishing urgent communication between rescue members in critical situations like, disaster or natural calamities. The sending and receiving data in MANET is depending on the routing protocols to adapt the dynamic topology and maintain the routing information. Consequently, This paper evaluates the performance of three routing protocols in MANET: ad-hoc on-demand distance vector (AODV), destination sequenced distance vector (DSDV), and ad-hoc on-demand multipath distance vector (AOMDV). These protocols are inherent from different types of routing protocols: single-path, multi-path, reactive and proactive mechanisms. The NS2 simulator is utilized to evaluate the quality of these protocols. Several metrics are used to assess the performance of these protocols such: packet delivery ratio (PDR), packet loss ratios (PLR), throughput (TP), and end-to-end delay (E2E delay). The outcomes reveal the AOMDV is the most suitable protocol for time-critical events of search and rescue missions.

Mobile nodes roaming around in the hostile environment of mobile adhoc network (MANET) play the role of router as well as terminal. While acting as a router, a node needs to choose a reliable routing protocol. Besides, an encryption algorithm is needed to secure data to be conveyed through the unfriendly atmosphere while acting as a terminal. We have implemented Elliptic Curve Cryptography (ECC) along with Adhoc On Demand Multipath Distance Vector (AOMDV) routing protocol to secure data transmission against blackhole attack in a MANET. ECC, a public key cryptography that works on discrete logarithm problem with a much smaller key size, has been used to encrypt data packets at source node before transmission. We have used AOMDV, a reliable routing protocol compared to its parent protocol, Adhoc On Demand Distance Vector (AODV), with a multipath extension, for routing. The encrypted packets transferring between nodes via AOMDV, has been proved secured against blackhole attack. The performance of the secured protocol has been analyzed in terms of different performance metrics and in terms of varying number of blackhole attacker nodes.

Energy consumption is a significant issue in ad hoc networks since mobile nodes are battery powered. In
order to prolong the lifetime of ad hoc networks, it is the most critical issue to minimize the energy
consumption of nodes. In this paper, we propose an energy efficient multipath routing protocol for
choosing energy efficient path. This system also considers transmission power of nodes and residual energy
as energy metrics in order to maximize the network lifetime and to reduce energy consumption of mobile
nodes. The objective of our proposed system is to find an optimal route based on two energy metrics while
choosing a route to transfer data packets. This system is implemented by using NS-2.34. Simulation results
show that the proposed routing protocol with transmission power and residual energy control mode can
extend the life-span of network and can achieve higher performance when compared to traditional ad-hoc
on-demand multipath distance vector (AOMDV) routing protocol.

Wireless communication technology is the biggest contribution to mankind. Vehicular ad hoc networks (VANETs) are the extensions to wireless network provide data transmission and emergency services. Vehicle-to-Vehicle communication (V2V) offers many services for vehicular environment, mainly to improve the safety in emergency rescue application. This kind of decentralized network requires new routing based technique to broadcast message. The V2V communication requires proper coordination between On-Board Units (OBUs) in the vehicles, and RoadSide Units (RSUs) on the roads to exchange any information among them. The proposed routing based application uses the combination of OBUs and RSUs of the VANETs to advise danger or emergency situations with V2V and RSUs message exchange. The desired routing protocol for this new application is AOMDV (Multipath) which is based on dynamic path selection over a IEEE 802.11p standard. The performance of the application will be evaluated through many simulations parameters of AOMDV protocol executed in highway city scenarios.

Deterministic channel models have been widely used in simulation and modeling of ad hoc network for a long time. But, deterministic channel models are too simple to represent a real-world ad hoc network scenario. Recently, random channel models have drawn considerable attention of the researchers in this field. The results presented in the literature show that random channel models have a grave impact on the performance of an ad hoc network. A comprehensive investigation on this issue is yet to be available in the literature. In this investigation, we consider both deterministic and random channel models to investigate their effects on ad hoc networks. We consider two different types of routing protocols namely single path and multipath routing protocols. We choose Destination Sequence Distance Vector (DSDV), Dynamic Source Routing Protocol (DSR), and Ad-hoc On-Demand Distance Vector (AODV) as the single path routing protocols. On the other hand, we choose Ad-hoc On-Demand Multiple Path Distance Vector (AOMDV) as the multipath routing protocol. The results show that some single path routing protocol can outperform multipath routing protocol under both deterministic and random channel conditions. These results surprisingly contradict the popular claim that multipath routing protocol always outperforms single path routing protocol. A guideline for choosing an appropriate routing protocol for adhoc network has also been provided in this work.

Mobile Ad-hoc Networks (MANETs) are self configurin
g, decentralized and dynamic nature wireless
networks which have no infrastructure. These offer
a number of advantages, however the demand of high
traffic flows in MANETs increases rapidly. For thes
e demands, limited bandwidth of wireless network is
the
important parameter that restrains the development
of real time multimedia applications. In this work,
we
propose a solution to utilize available bandwidth o
f the channel for on demand multiple disjoint paths
.
The
approximate bandwidth of a node is used to find the
available bandwidth of the path. The source choose
s
the primary route for data forwarding on the basis
of path bandwidth. The simulation results show that
the
proposed solution reduces the frequency of broadcas
t and performs well in improving the end to end
throughput, packet delivery ratio, and the end to e
nd delay.
