Abstract
To improve the performance of Ad hoc on-demand multipath distance vector (AOMDV) protocol, we proposed NS-AOMDV which is short for “AOMDV based on node state”. In NS-AOMDV, we introduce node state to improve AOMDV’s performance in selecting main path. In route discovery process, the routing update rule calculates the node weight of each path and sorts the path weight by descending value in route list, and we choose the path which has the largest path weight for data transmission. NS-AOMDV also uses the technology of route request (RREQ) packet delay forwarding and energy threshold to ease network congestion, limit the RREQ broadcast storm, and avoid low energy nodes to participate in the establishment of the path. The results of simulation show that NS-AOMDV can effectively improve the networks’packets delivery rate, throughput and normalized routing overhead in the situation of dynamic network topology and heavy load.

Summary
Mobile ad hoc network is a self-organized and special wireless communication network, which is made up of some mobile nodes by using distributed protocols. Since each node in ad hoc network has the function of the host and router, it has the characteristics of flexibility and convenience in deployment. In the situation of no fixed network infrastructure, mobile ad hoc network can communicate with each other by using multi-hop way, and provide the convenience to some special occasions such as medical, meeting, military and so on. Routing protocol [1] plays an important role in the communication between nodes. We introduce NSAOMDV, a protocol based on node state that can effectively improve the performance of AOMDV.
