摘要
研究在无线传感器网络中如何选择活动的路由节点及其传输范围,以有效节省能量的消耗。在节点随机布设的线性网络中,当网络传输流量一定的条件下,提出了三种路由节点选择及其传输范围调整算法,获得最优无线传输范围与通信流量之间的关系,数值计算证实了其中的动态规划算法可以选择到最优能量消耗的路由节点及其传输范围。
This paper investigates how to determine the active nodes in wireless sensor networks (WSNs) and the optimal transmission ranges for each active routing nodes in order to save the energy consumption. Three algorithms are presented and the relation between the. optimal transmission ranges and the communication traffic is obtained in a simple linear network with the candidate route nodes randomly deployed. Numerical results show the dynamic programming algorithm can select the optimal route nodes and their transmission range and is more efficient than the other two algorithms.
