Optimization of DSR Routing Protocol Based on Genetic Algorithm

AD HOC is a self-organized and self-managed network without basic facilities,all of whose nodes possess the functions of the terminal and the router.So the network can forward packet by node router discovery mechanism,and keep the routing maintenance.DSR is a routing protocol designed for AD HOC network,whose functions are more efficiently but impose no restrictions on delay,bandwidth,packet loss rate,etc.That is to say,without QoS support,DSR is optimized on the router discovery by means of genetic algorithm so that QoS can guarantee it.Comparisons are conducted on the DSR routing protocol based on genetic algorithm with the original on delay,delivery ratio and network overhead by the simulate experiment,and the impact of the improved routing protocol over the quality of network is analyzed.
