基于多属性决策的无线传感器网络路由算法

Multiple Attribute Decision Making Routing in Wireless Sensor Networks

针对传感器网络容易出现数据流量集中于少数路径的现象,提出了一种基于多属性决策的能量平衡路由(Multiple Attribute Decision Making Routing,MADMR)算法。MADMR算法通过综合评价节点的能量、偏好及位置等信息,选择最优的节点转发数据,它考虑了网络的能量分布状况,使数据流量得到合理的分配,从而使网络的能量消耗趋向平衡,延长了网络生存时间。仿真实验表明MADMR算法达到了预期的效果且具有良好的环境适应性。

A multiple attribute decision making routing （MADMR） algorithm in wireless sensor networks was proposed to avoid the concentration of a large quantity of data in a few paths. A sensor node can choose an optimal node to relay the data by comprehensive consideration of the energy, the preference and the location information of its neighbor nodes. MADMR algorithm can lead an appropriate allocation of the data and the sensor network could obtain a much more even energy distribution, accordingly the lifetime of the sensor network will be prolonged. Simulation results show that the MADMR algorithm has prospective effect and good performance.
