【摘要】 在无线传感器网络中,为有效节省能量的消耗,一般将多跳路由上的冗余节点设置成休眠状态。针对节点均匀分布的线性网络,在候选路由节点随机确定,且各节点可有不同传输半径的情况下,利用动态规划算法选择合适的活动路由节点及其传输半径,达到总体最优能量消耗。数值结果证实算法的有效性。更多还原

【Abstract】 In wireless sensor networks(WSNs),energy is saved by setting the redundant nodes in sleeping mode along the multi-hop routes.In a linear network with the sensors uniformly distributed and the candidate route nodes randomly deployed,a dynamic progra-mming algorithm is employed to select the optimal route nodes and their transmission ranges when the node communication radius can be various.Numerical results show the efficiency of the algorithm.更多还原
