为了延长无线传感器网络的工作时间,针对LEACH算法中能量分布不均衡以及簇头节点能量浪费的问题,提出了一种基于LEACH协议的兄弟节点算法(LEACH-BN,LEACH-Brother Node):通过簇内兄弟节点调整节点密度、簇头兄弟节点改进簇头选取和转发机制、簇间兄弟节点向基站转发数据。分析和仿真同时表明,改进后的算法实现了WSN中节点能量的全面均衡,提升了首节点和网络的生存时间,均衡弱势节点,增强系统的可靠性。
In order to prolong the working time of wireless sensor network (LEACH-BN, LEACH-BN), aiming at the problem of unbalanced energy distribution and energy waste of cluster head node in LEACH algorithm, a LEACH-BN (LEACH- The sibling nodes adjust the node density, the cluster head siblings improve the cluster head selection and forwarding mechanism, and the sibling nodes in the cluster forward the data to the base station. Analysis and simulation also show that the improved algorithm realizes the overall energy balance of nodes in WSN, improves the survival time of the first node and the network, balances the weak nodes and enhances the reliability of the system.
