Performance Comparison of AODV and B-AODV Routing Protocols

Manets are self configuring networks. Why manets are self configuring networks? It’s because they possess they dynamic topology. it is difficult to predict the topology of manets .It presents an optimized protocol: B-AODV, based on the shortage of routing finding and routing repair of AODV. In B-AODV, first through reverse request by sending BRREQ replace of RREP, it reduces the time of routing finding. Second, two hops IP record in control messages and route table can improve the rate of routing repair and reduces the times of routing findings. And it improves the function of Ad Hoc network. This simulation experiment is based on NS2 and compared the performance of AODV and B-AODV. And it compared the differences of control packets, ratio of packets, end to end delay for AODV and BAODV. It shows that B-AODV is better than AODV.
