Abstract: In this paper,we propose an improved algorithm route——AODV-Cache based on AODV, which is mainly focused on the improvement of the routing table, and aimed at improving the utilization of the available routes and network performance. The simulation results show that,compared with AODV routing protocol,AODV-Cache routing protocol has a clear advantage in terms of routing overload, the average of end-to-end delay and the packet reception rate.
