A Mobile Ad hoc NETwork (MANET) consists of wireless Mobile Nodes (MNs)that cooperatively communicate with each other without the existence offixed network infrastructure. Depending on different geographical topologies,the MNs are dynamically located and continuously changing their positions.The fast-changing characteristics in MANETs make it difficult to discover

routes between MNs.

A central challenge in the design of Ad hoc networks is the development ofdynamic routing protocols that can efficiently find routes between 2communication nodes. The routing protocols must be able to cope up withhigh degree of node mobility that often changes the topology drastically andunpredictably. Therefore it becomes important to design efficient andreliable multihop routing protocols to discover, organize, and maintain theroutes in MANETs. Recent interests in the design of ad hoc routing algorithmsinclude applications for the military, the Inter-Vehicle Communication (IVC),the Personal Communication Services (PCS), and the sensor networks.

Different types of ad hoc routing protocols have been developed for theMANETs. The topology-based routing protocols can be categorized into theproactive (such as DSDV [1]) andthe reactive algorithms (such as AODV [2] and DSR [3]). The proactiverouting protocols periodically maintain tables at each MN to store consistentand up-to-date routing information;while the reactive algorithms initiate route discovery and packet forwardingprocesses based on the request from the source node. The performancecomparison between different existing ad hoc routing protocols has beenstudied in several research [4] [5].

The various Ad hoc routing protocols have their unique characteristics.Hence in order to find out the most adaptive and efficient routing protocol forthe highly dynamic topology in Ad hoc networks, the routing protocolsbehaviour has to be analyzed using varying node mobility speed, traffic andnetwork size etc. Thus the goal of this project is to carry out asystematicperformance comparison of Ad hoc routing protocols undermobility models.

The main aim of this project is:

Acquiring detailed understanding of Ad hoc routing protocols, such asDSR and AODV

Implementing the moblity models, such as Random waypoint model,Manhattan grid mobility model

Analyzing the performance differentials of routing protocols undermobility
