Mobile ad-hoc Network [MANET] is the collection of mobile nodes deployed with the short-lived purpose. It is the most innovative and useful variety which provide the facility to establish communication without the prerequisite of any infrastructure. Here, wireless communication medium is usually used for communication and connection establishment purpose. Generally, it is deployed with mobile nodes but can be used for stationary design also. Open nature communication makes it vulnerable for several security threats. This paper has considered the simulation of AODV and ODMRP using Qualnet 5.2 simulator.

Mobile Ad Hoc

 A Wireless Mobile Ad-hoc Network consists of variety of mobile nodes that temporally kind a dynamic infrastructure less network. To modify communication between nodes that don’t have direct radio contact, every node should operate as a wireless router and potential forward knowledge traffic of behalf of the opposite node. In MANET Localization is a fundamental problem. Current localization algorithm mainly focuses on checking the localizability of a network and/or how to localize as many nodes as possible. It could provide accurate position information foe kind of expanding application. Localization provide information about coverage, deployment, routing, location, services, target tracking and rescue If high mobility among the mobile nodes occurs path failure breaks. Hence the location information cannot be predicted. Here we have proposed a localization based algorithm which will help to provide information about the localized and non-localized nodes in a network. In the proposed approach DREAM protocol and AODV protocol are used to find the localizability of a node in a network. DREAM protocol is a location protocol which helps to find the location of a node in a network whereas AODV is a routing protocol it discover route as and when necessary it does not maintain route from every node to every other. To locate the mobile nodes in a n/w an node identification algorithm is used. With the help of this algorithm localized and non-localized node can be easily detected in respect of radio range. This method helps to improve the performance of a module and minimize the location error and achieves improved performance in the form of UDP packet loss, received packet and transmitted packets, throughput, routing overhead, packet delivery fraction. All the simulation done through the NS-2 module and tested the mobile ad-hoc network.

Aodv Protocol

In Wireless ad-hoc network, the infrastructure of MANET's differ to each other due to the topology of MANETs changes time to time because the mobile nodes of MANET's are movable. In MANETs protocols, if any node wants to communicate with another node then they establish a path with the help of adjacent node due to this the security in MANETs protocol is vulnerable. Thus, there are various types of attacks are try to break the security of MANETs protocol. AODV is a popular and most usable protocol of MANET and Black Hole Attack is a severe attack that affects the functionality of AODV protocol. The malicious node treat to the source node which have freshest and nearest path for the destination. In this work, my prime focus specifically is on follow the security against Black Hole Attack. I proposed AODV protocol capture some extra effort for source node and destination node which based on best possible effort (heuristic) with appropriate simulation using ns-2.35.

This paper focuses on secure data communication between nodes in Ad-Hoc networks by employing IPSec (Internet Protocol Security). In wireless communication, Ad-Hoc network is a new paradigm since, which is used for highly sensitive and emergency operations. Ad-Hoc network is considered a number of mobile nodes that are connected through wireless interfaces and moves arbitrarily. Ensuring security is one of the main issues due to its infrastructure less solutions. This research aims for IPSec protocol that provides security for an Ad-Hoc networking in a various applications. IPSec incorporates security model, i.e. AES (Advanced Encryption Standard) into its framework. In this work, we consider the problem of incorporating security mechanisms to securing data communication for Ad-Hoc networks. We look at AODV routing protocol (Ad-Hoc On-Demand Distance Vector) in detail and it is used for secure routing. Simulation of IPSec protocol is simulated using NS-3 simulator. Results from NS-3 simulator is compared with AH, ESP, and AES in terms of Quality of Service parameters throughput, average processing time and average end-to-end delay.

Hoc Networks

A Mobile Ad hoc NETwork (MANET) is a self-organizing, infrastructure-less network of mobile nodes connecting by wireless links. In operation, the nodes of MANETs do not have a central control mechanism. It is known for its properties of routable network, where each node acts as a router to forward packets to other specific nodes in the network. The unique properties of MANET have made it useful for large number of applications and led to a number of security challenges. Security in the mobile ad hoc network is a very critical job and requires the consideration of different security issues on all the layers of communication. The countermeasures are the functions that reduce or eliminate security vulnerabilities and attacks. This chapter provides a comprehensive study of all prominent attacks in Mobile Ad Hoc Networks described in the literature. It also provides various proactive and reactive approaches proposed to secure the MANETs. Moreover, it also points to areas of research that need to be investigated in the future.
