This paper elaborated the working mechanism,communication mode and application of mobile ad hoc network.Besides,it analyzed the greedy perimeter stateless routing (GPSR) protocol based on geographic location.For the reason that the GPSR protocol may result in a higher packet loss rate because of high relative speed,this paper modified and implemented the improved greedy perimeter stateless routing (IGPSR) algorithm which took into account the speed and direction of the source nodes,destination nodes,and alternative relay nodes.The position of the node could be calculated and predicted with the current speed of the node,thus the best relay node was identified.Simulation experiments showed that the IGPSR routing protocol had a lower packet loss rate than the GPSR routing protocol when nodes moving at high speed.
