摘要
基于LEACH协议,提出了一种改进方案,对LEACH协议的不足进行了改善。此方案中,簇头的选择取决于节点的剩余能量,且簇头数量与网络中的剩余节点数量相关,更符合网络特性。此外,改进方案对簇中节点数量进行了限制,使得分簇更加均匀,并采用了适应性信道分配原则,更加适用于动态网络。计算机仿真结果表明,与LEACH协议相比,采用改进方案后汇聚节点接收到的数据量明显增加,网络性能得到改善。
An improved scheme is proposed based on LEACH in this paper. It improves LEACH in several aspects. In the proposed scheme, the head selection is adjusted to the energy reserve of local nodes and the number of cluster is dynamic. Besides that, it constructs clusters based on the number of cluster members and adaptive channel assignment is also applied. Simulation results that the proposed scheme delivers more data to the base station than LEACH and the performance of network is improved.
