This paper engages in intensive study on a typical routing protocol based on geographical position——Location Aided Routing(LAR) and puts forward an Improved Location Aided Routing(ILAR) in allusion to the inefficiency of LAR.ILAR protocol consides the distance from routing node to the destination node and the link holding time between them when the transmission node is chosen,which guarantees more stable established path,lower loss rate in the transmission of data,and reduces the control consume effectively.Furthermore,when source node can not find any path to destination node,ILAR re-builds routing path through local flooding instead of global flooding in LAR to further reduce the netwok control overhead.Simulation results show that,compared with LAR,the successful packet arrival rate of the ILAR significantly increases and the control grouping consume dramatically decreases.
