中文摘要：
针对无线多媒体传感器网络（WMSNs）节点能耗问题,提出了一种基于粒子群优化的多路径自适应流量分配路由MATDR-PSO算法。通过建立能效优化模型,将最小能耗和能耗均衡2个特性转化为多目标优化问题;利用粒子群优化算法动态分配多路径上各条链路流量来实现网络的能效优化。仿真实验表明：MATDR-PSO算法能够在降低全网节点消耗总能量的同时保证能耗的均衡特性,显著提高了网络的生命周期。
英文摘要：
Considering at the energy consumption of node in wireless multimedia sensor networks, a multipath adaptive traffic distributing routing MATDR-PSO algorithm based on PSO is proposed. An energy- efficiency optimizing model is built which can translate the minimum of energy consumption and its equilibrium characteristic into multi-objective optimization problems; and link flow on multipath is dynamically distributed by particle swarm optimization algorithm to achieve energy-efficiency optimizing of the network. Simulation results show that the algorithm can reduce the total energy consumption of the whole network nodes and balance its distribution simultaneously, the life cycle of network is prolonged significantly.
