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.

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.

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
d-
el only. This is not sufficient to evaluate the beh
avior of a routing protocol. Therefore, in this pap
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
he
increasing node mobility forall mobility models. Al
so, average end-to-end delay is also vary with vary
ing
node speed, initially upto 20 nodes in all mobility
models delay is minimum.

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.

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.

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.

Data communication becomes an important issue when infrstruktur in the area of tourism cannot be built. Common law or awig-awig and local regulations strictly limit infrastructure development in the Bali tourism, are aiming to preserve the tourist area.
Wireless technology and ad hoc communication allow device communicates directly with other devices without any fixed infrastructure. Appropriate technologies are possible to be implemented in areas that do not have fixed infrastructures such as in the site of tourism in Bali. Testing and comparison protocols AODV, AOMDV and DSDV performed to obtain optimal protocols for ad hoc communications on a moving vehicle (VANET) in the tourist area of Kuta, airport and Jimbaran beach, Bali.
According to the test results, AOMDV protocol shows high packet delivery performance with PDR average reach 97% and has a delay which tend to be more stable than AODV and DSDV protocol.

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.

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

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.

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.

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.

Abstract- Number of techniques has been planned supported packet secret writing to safeguard the communication in MANETs. STARS functioning supported stastical characteristics of captured raw traffic. STARS discover the relationships of offer to destination communication. To forestall STAR attack associate offer hidding technique is introduced.The pattern aims to derive the source/destination probability distribution. that's the probability for each node to entire traffic captured with link details message source/destination and conjointly the end-to-end link probability distribution that's the probability for each strive of nodes to be associate end-to-end communication strive. thence construct point-to-point traffic originate and then derive the end-to-end traffic with a set of traffic filtering rules; thus actual traffic protected against revelation attack. Through this protective mechanism efficiency of traffic enlarged by ninety fifth from attacked traffic. For a lot of sweetening to avoid overall attacks second shortest path is chosen.

A Mobile Ad-hoc Network or MANET is a collection of mobile nodes sharing a wireless channel without any centralized control or established communication backbone. We can classify the routing protocol as flat and hierarchal routing and flat routing protocols are classifying into reactive (source initiated) and proactive (table driven). In this paper we mainly focusing on reactive routing protocols i.e. Adhoc On demand Multipath Distance Vector (AOMDV) for better performance in simulation by comparing Ad-hoc On demand Distance Vector (AODV), and Dynamic Source Routing (DSR).AODV and DSR protocols are unipath routing protocols but AOMDV is multipath. The performance of three routing protocols is analyzed in terms of their Packet Delivery Fraction, Average End-to-End Delay, Routing overhead, Route Discovery Frequency. NS2 simulator is used for comparison and critical analysis of AOMDV is done to find its merits and demerits.

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.
