| 摘 要： | 在分簇路由协议中，延长传感器网络的寿命，很大程度上依赖于簇头节点选择的合理性。提出一种基于传感器节点分布密度的分布式成簇算法，该算法是对LEACH算法的改进，在选取簇头的时候除了考虑节点轮流成为簇头的问题，同时还考虑各节点的分布密度。仿真实验证明，新算法能比LEACH算法更有效地降低网络的能量消耗，均衡网络能耗水平，从而使得传感器网络的生命周期在LEACH算法的基础上有较大提高。

| Abstract: | In cluster-based routing protocols,prolonging the life of the sensor networks mainly depends on the rational selection of cluster heads.In this paper,a new distributed clustering algorithm based on the distribution density of sensor nodes is proposed,which is an improvement of the LEACH algorithm.When selecting cluster heads,the new algorithm considers not only the problem that sensor nodes shall become cluster heads in turn,but also nodes' distribution density.Simulation results show that the new algorithm... |
