Performance Analysis and Comparison of MANET Routing Protocols

Advances in wireless technology and portable computing along with demands for greater user mobility have provided a major movement towards development of ad-hoc networks. The main Method for evaluating the performance of MANET’s is simulation. An extensive simulation is performed using NS-2 simulator and end to end delay, packet delivery ratio, packet loss ratio, throughput and jitter for Reactive protocols TORA,DSR and proactive protocol DSDV for TCP and CBR traffic patten are evaluated for different scenarios i.e. pause time, simulation time and no of nodes . At the end it is concluded that in case of TCP DSDV(Proactive) is best and in case of CBR DSR(Reactive) is best. Performance of TORA is average in all cases except packet loss.
