An improved link repair method in AODV routing protocol


The rapid development of the communication technology gives the heavy research on wireless networks. In recent years, more and more research bases on the Mobile Ad hoc NETwork (MANET) which has many applications in military and civilian environments. MANET is a wireless self-organized distributed network. The routing protocol is the main part in communication networks. Ad hoc On-Demand Vector routing protocol (AODV) is a popular routing protocol in MANET and other wireless networks. It is efficiently to discover and maintain routes between nodes which need to communicate with each other. Because of the mobility of the node in wireless network, the network topology changes frequently that is the main reason of the link break. Link repair is more and more important in route maintenance. In this paper, a new link repair method is proposed. It combines the source repair and local repair. The NS-2 is used to simulate the strategy. The result illustrates that the proposed method has good performance in packet delivery ratio and throughput.
