Consistency of Geographic Routing Protocol for high density MANET

Mobile ad hoc network is a collection of self organized nodes. They form a temporary network without additional infrastructure like wireless access points. Such network does not have any centralized control. Here every node can communicate directly with other nodes in the network. Mobile ad hoc network communicate one to the other through broadcast radio transmissions, i.e., transmissions that reach all the terminals within the transmission power range. In recent years several routing protocols are developed for mobile ad hoc networks. Some of them are DSDV, AODV, TORA, DSR and GRP. This paper does the distance based analysis of Geographic Routing Protocol for random mobility of nodes in MANET. The simulation environment is created in Opnet 14.0. We conclude that the performance of GRP for high density network is more consistent compare to the less dense network.
