Aimed at the node mobility and shared wireless links in Mobile Ad Hoc Network(MANET),this paper proposes a route self-healing technique for source-initiated routing protocols by restricting the route-required zone on forward nodes in order to reduce the overhead and time delay during route maintenance and allow continuous packet forwarding for fault resilience.The NS-2 based simulation shows that the throughput is improved and the overhead is decreased for source-initiated routing with route self-recovery in the case of highly dynamic environments and heavy traffic loads,which proves that the proposed protocol is more robust and stable than other protocols.
