Research of AODV Routing Protocol for Ad Hoc Networks

In special situation such as military communications,earthquake or flood and so on,the routing protocol of Ad Hoc network can not meet the real-time communication.This paper presents an optimized protocol: B-AODV based on the shortage of routing finding and routing repair of 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 experiments are 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 B-AODV.It shows that B-AODV is better than AODV.
