摘　　要：由于复杂度低、扩展性好,地理位置路由广泛应用于无线传感网络(WSN)。传统地理位置路由只依据节点位置决策下一跳转发节点,并没有考虑节点能耗。为此,提出转发节点优化的地理位置路由(FNO-GR),旨在提升网络寿命,减少死亡节点数。FNO-GR路由构建邻居节点集,依据离信宿距离,从邻居节点集中选择候选转发节点,并考虑节点剩余能量,从候选转发节点中选择最优的节点作为下一跳转发节点。仿真结果表明,与最短地理位置路由(SGR)协议相比,FNO-GR路由的平均网络寿命提升约5.08%,死亡节点数下降了约7.99。One of the most popular routing protocols for wireless sensor networks(WSNs)is the family of geographical routing protocols because of its low complexity and good scalability.However,traditional geolocation routing only makes next-hop forwarding node decisions based on location of nodes,without considering energy consumption of nodes.Therefore,forward node optimization-based geographical routing(FNO-GR)is proposed to improve network life and reduce the number of dead nodes.The FNO-GR route first constructs the neighbor node set,then selects the candidate forwarding node from the neighbor node set according to the distance from the sink,and then selects the optimal node from the candidate forwarding node as the next-hop forwarding node considering the residual energy of the node.The experiment results show that FNO-GR get a longer average of network lifetime 5.08%and reduce dead nodes 7.99%,compared to the shortest geographical routing(SGR)approach.
