GAF协议是一种基于地理信息的无线传感器网络路由协议，由于采用多跳传输，将导致热区的产生。提出了一种优化邻居表算法，可以有效辨识GAF虚拟网格内的节点密度，从而选择密度大的网格通行，以均衡热区能耗，延长网络寿命。仿真结果验证了该算法的可行性。

GAF protocol is a routing algorithm of wireless sensor networks which is based on geographic information. Multi-hop communication of wireless sensor networks gives rise to hot spot. In this paper,an optimized neighbour algorithm is proposed. This algorithm could distinguish the density of virtual cell,so as to choose the cell with higher density. It can balance the load of nodes in hot spot and lengthen the life time of networks. Simulation results validate the feasibility of the algorithm.
