摘要：

针对无线传感器网络中现有路由能耗不均问题,提出一种基于多属性决策的能量均衡路由算法(distributed multiple attribute-based energy-balance routing,DMAE),通过引入节点负载预测机制、传输总能耗(total transmission energy cost,TEC)等,建立多属性决策模型,将节点的前向邻居的能量、综合负载、传输总能耗等参数定义为模型中的属性,根据构建的前向邻居列表信息,使用相对熵计算各属性的权重,确定决策模型。节点依据该决策模型选出最优的前向邻居中转数据,使全网能耗均衡。仿真结果表明,与MTE(minimum transmitted energy)、EAR(energy-aware routing)、DEBR(distributed energy balanced routing)协议相比,DMAE能够更好地均衡全网能量分布,提高能量利用率,从而延长网络生存时间。
