CPRM: Cooperative Position based Routing scheme for MANETs

Abstract

A mobile ad hoc network is a wireless communication network, where nodes that are not within direct transmission range of each other will require other nodes to forward data. Routing is difficult in MANET because mobility may cause radio links to break frequently. Mobile nodes keep changing their position in an unpredictable manner. A routing algorithm must keep track of the destination's position and modify routes whenever the old routes become stale. In a high mobility MANET, although every mode can move freely, they usually follow some mobility patterns. Fast changes of topology increases the complexity of routing. Due to mobility of the nodes to another location, some of the data packets will be missed and does not deliver the data packets to the destination in a reliable manner. This project proposes a Cooperative Position based Routing scheme for mobile ad hoc networks (CPRM). In this, the routing is carried out based on the positions of nodes in the network. The main objective of this project is to achieve the reliable data delivery in the network. In this scheme, the source node finds a forwarder node from its neighbor list, for transmitting data. The forwarder in turn finds the next forwarder and this process continues until the destination is reached. Performance of the proposed system is compared with that of AODV using Network Simulator.
