【摘要】针对无线传感反应网络中事件频发区域内执行器节点能耗过大问题,提出一种基于熵权的任务分派算法,利用拍卖机制,建立基于熵权的执行代价评估模型,并根据网络的实际情况,将任务元分派建模成平衡或者非平衡整数规划问题,使任务并发执行.仿真实验表明,网络实时性和能耗均衡性都得到了改善.%Aimed at \a tasks assignment algorithm based on entropy was proposed to make the whole network energy consumption more balanced. Considering network situation,the entropy-based cost of taking action model was established by using auction method. The task assignment problem among actors was formulated as a balanced or non-balanced task assignment optimization problem, different task units were executed in parallel to enhance higher real-time response. The result of simulation shows that the algorithm can provide more balance in energy consumption and higher real-time performance. 【总页数】4页(106-109)
