中文摘要: 无线传感器网络的能耗决定了网络的生存时间,如何设计有效的算法来延长网络的生存时间是一个重要的研究课题。针对矩形传感器网络,提出一种基于分层的功率控制算法,通过分析节点的能耗来计算层的宽度和节点的通信半径,以达到网络能耗的均衡分布。仿真实验表明,算法能有效延长网络的生存时间。
Abstract:The lifetime of a wireless sensor network (WSN) directly lies in the power consumption of the network. Thus one of the important problems is how to design an effective algorithm to prolong the lifetime of the sensor network as much as possible. In this paper, a layer-based power control algorithm is proposed for rectangular field sensor network. In this scheme, the width of the layers and communication radius can be computed according to nodes energy consumption. Hence, the energy consumption of the networks can be balanced effectively. Simulation results show that the algorithm could effectively extend the lifetime of the networks.
