Performance analysis and simulation of expansion DSR route protocol

According to the DSR route protocol insufficiency: the slow speed in route discovery process.The expansion DSR route protocol—IDSR protocol is proposed.The performance index with the traditional DSR protocol is analyzed and compared.The protocol through limits DSR in the route request process to the entire network flooding mechanism,requested the route scope to limit in certain region,then cascade expansion request scope from the actual situation,enable it to have the expansion function.The simulation result indicated that the basic performance index of the protocol would be better then the traditional DSR protocol.
