Performance Comparison of OLSR, GRP and TORA Using OPNET
A MANET is an autonomous collection of mobile users that communicate over relatively bandwidth constrained wireless links. Since the nodes are mobile, the network topology may change rapidly and unpredictably over time. The network is decentralized, where all network activity including discovering the topology and delivering messages must be executed by the nodes themselves, i.e., routing functionality will be incorporated into mobile nodes. In this paper, routing protocols OLSR, GRP and TORA for mobile ad hoc network are compared on the basis of delay, load, media access delay and throughput.
