摘要
针对无线传感器网络中覆盖保持的节点调度算法存在的利用率低、能量不均衡问题,提出一种改进的算法,将网络节点划分为若干个相异的节点集合,根据集合平均能量设置一个权值,通过权值大小选取合适的节点集合进行工作,从而均衡节点能量、延长网络的生命期。通过模拟仿真实验证明了算法的有效性。
Classical Coverage-Preserving Nodes Scheduling Algorithm（CPNSS） of the Wireless Sensor Network（WSN） has the problems of low efficiency and energy non-balance. According to the problems, this paper proposes an improvement algorithm. It divides all the nodes into some dissimilar set, sets a priority-weight for each set by its average energy, and selects different sets to work according to their priority-weight, so as to achieve the balance of the node energy and prolong the life-time of the network. Experimental results prove its effectiveness.
