An improved NCR-AODV (improved neighbor change ratio AODV) that can greatly reduce route cost and end-to-end delay is presented. A piggyback mechanism is added into the AODV protocol. Then the weighted neighbor change ratio is introduced which means jointly considering NCRs both at the current time and historical times. The results of NS2 simulation show that the proposed Improved NCR-AODV can greatly enhance the network performance.
