该文针对传感器节点能量受限的特点建立能效优化模型,该模型兼顾网络传输能耗和能耗均衡特性,以最大化网络节点总剩余能量和最小化剩余能量的方差为目标,通过合理分配多条路径的流量来优化网络能效.利用权衡评价函数实现了模型的求解,进而提出一种多径流量分配路由(MFAR)算法.仿真实验表明,该算法能够合理配置各路径流量,显著提高网络能量效率,达到在降低网络能耗的同时保证能耗分布均衡的目标.%Considering at the characteristic that the energy of node is limited in wireless sensor networks, an energy-efficiency optimizing model both considering transmission energy consumption and its equilibrium characteristic is build in this paper. To make maximum of the total remaining energy and minimum of the remaining energy variance as optimal objectives, it optimizes energy efficiency of the network by reasonably allocating the flow on multipath. The weigh evaluation function is used to solve this model, and then a Multipath Flow Allocating Routing (MFAR) algorithm is proposed based on it. Simulation results show that, MFAR algorithm can reasonably allocate the flow on multipath, improve the network energy efficiency significantly, and achieve the goal of reducing energy consumption and balancing its distribution simultaneously.
