AODV protocol is a typical reactive routing protocol in Ad Hoc network.This protocol applies only to the two-way transmission channel. Also, the routing table only maintains one route to the specified destination node; here improving the AODV protocol is necessary. This article makes a definite improvement for the AODV protocol used in certain occasions. Through simulated experiments, it has been proven that the new AODV protocol can improve the network’s input and effectively reduce the network latency.
