To Analyze MANET Routing Protocol using Mobility

A wireless Ad-Hoc network [7, 8] is a collection of mobile/semi mobile nodes with no pre-established infrastructure forming a temporary network. Each of the nodes has a wireless interface and communicates with each other over either radio or infrared media. Laptop computers and personal digital assistances (PDAs) that communicate directly with each other. Nodes in the Ad-Hoc network are often mobile, but can also consist of stationary nodes, such as access points to the Internet. Semi-mobile nodes can be used to deploy relay points in areas where relay points might be needed temporarily. The mobile nodes can receive and forward packets as a router. Routing is a critical issue in MANET. Therefore focus in this paper is to compare the performance of three routing protocols AODV,DSDV and OLSR for wireless ad hoc networks in a simulated environment using Random Waypoint (RW) Mobility Model, Freeway (FW) Mobility Model, Manhattan Grid (MH) Mobility Model and Reference Point Group (RPGM) Mobility Model against different parameters considering UDP as the transport protocol with CBR as traffic generator for by varying no. of nodes in terms of packet delivery ratio, end to end delay, routing overhead and throughput.
