Since the geographical location routing(GEAR) algorithm has some shortcomings in forwarding query message and solving routing hole problem,this article proposed an improved scheme.Based on some rule,the improved GEAR algorithm established multipath from the source node to the target region,at the same time,it can avoid the identical node encountering the same hole again.Both of the algorithms were emulated by NS2,the simulation results show that the improved algorithm can better balance the network loads and increase the network lifetime.
