摘　　要：在均衡整个网络节点能量的前提,从凸显节点传输数据主要功能的角度出发,提出一种基于FCFG路由算法的节能改进算法EFCFG.该算法在借鉴FCFG算法提出的前向簇头和前向网关的路由选择上,综合考虑网络各个簇头节点的剩余能量和每轮其必需消耗的工作能量之间的关系,分析和改进网络的能量模型.通过实验在网络生存周期、数据吞吐量、端到端平均时延三方面上进行了仿真,证实该算法确实优于FCFG算法.Proposed an energy-saving improvement algorithm based on the FCFG algorithm, in order to balance of the energy of the network nodes, and much more focus on the data transmission of the nodes. The NFCFG algorithm draws on the experience of the FCFG algorithm, which proposed the concept of forward cluster head and forward gateway, considers the rest energy between the working energy in each round of the cluster head node, it analyzes and improves the network energy model. It shows that on the simulation result the EFCFG algorithm is much more batter than the FCFG algorithm in the work lifetime, data throughput, average delay in end-to-end.
