However, the use of geographic routing protocols to build routing, you must first know the location of the destination node. But in Wireless Ad Hoc network, the node may change location at any time, so there must be a location server (Location Server) to record the location information of all nodes, while the mobile node must be frequently updated to the location server the current location of the latest information to keep the location information server in the success rate, but the speed and direction of the mobile node is not fixed, frequent updates but increased the number of packets, and accelerated the relay node's energy consumption, not only lack of efficiency, but also a waste of network bandwidth. In this article, we will combine fixed and predictable way from the return type of return method, and then add a shortcut to the priority mechanism and target tracking test. In many different simulated environmental testing, the experimental results show that our method can really achieve our desired results.
