摘要
在众多的无线传感器网络分簇路由协议中,低功耗自适应分簇(Low Energy Adaptive Clustering Hierarchy,LEACH)算法是其中比较流行的协议之一,但它并没有考虑到每个节点的能量状态,而且最优簇首数一旦确定,整个网络通信期间不再改变,因而不能更有效地提高网络的生存时间。文章在LEACH协议的基础上提出了一种改进的高能效无线传感器网络协议—EECRP(an Energy Efficient Cluster Routing Protocol)。仿真结果表明,与LEACH相比,EECRP具有更好的能量有效性,并且提高了无线传感器网络的寿命。
Among multiple Wireless Sensor Network (WSN) hierarchical routing protocols, Low Energy Adaptive Clustering Hierarchy (LEACH) is a fairly popular one, but it does not take into account the energy status of each node in the network, and if and when the optimum number of clusters is fixed, it will not be changed in the entire network communication period, thus it is impossible to enhance the network lifetime more effectively. Thus, on the basis of LEACH protocol, an improved Energy Efficient Cluster Routing Protocol (EECRP) is proposed. The simulation results show that comparing with LEACH, EECRP has much better energy efficiency and prolongs the lifetime of WSN.
