- 摘要:
- LEACH(lowenergy adaptive clustering hierarchy)是一种有效延长网络生命周期的通信协议，其组网过程中存在聚类大小范围不定和簇间干扰现象.针对该问题，提出基于移动节点的LEACH改进型算法.节点以一定半径广播成簇消息限定聚类大小，减少簇首通信干扰.针对网络运作一段时间后出现能量过低或者不平衡的聚类，加入移动式感测节点，移动至聚类担任簇首，延长网络生存时间.实验结果与分析表明新方法远好于LEACH.
- Abstract:
- The lowenergy adaptive clustering hierarchy (LEACH) is an energyefficient protocol that maximizes network lifetime, but its cluster range is unstable and there can be disturbances between clusters in the network setup process. This paper presents an improved LEACH algorithm based on mobile cluster heads. With the algorithm, sensor nodes broadcast cluster updates and confine cluster range to a set radius so as to reduce disturbances between cluster heads. As clusters lose energy or become unbalanced after a period of network operation, mobile sensors are added to clusters and promoted to cluster head in order to prolong the network survival time. Experimental results and analysis indicated that the performance of the new method is far better than basic LEACH.
