| 摘 要： | 针对低功耗自适应集簇分层型协议(LEACH) 簇头选举的盲目性问题、簇内节点能量消耗不均衡问题以及一跳的通信方式造成的能量大量耗费问题,提出了基于"生命游戏"的LEACH协议改进算法. 通过对节点剩余能量的估算实现对簇头选举机制的优化,并提出"生命游戏"睡眠调度模型和利用邻居节点作为转发节点的多跳通信方式. NS2仿真结果表明,改进的协议有效延长了无线传感器网络的存活时间,提高了数据的发送量.

| Abstract: | For the blindness of cluster head election, the imbalance of energy consumption in the cluster and the substantial energy consumption in communication with a hop in low energy adaptive clustering hierarchy (LEACH) protocol, an improved algorithm of the LEACH protocol based on "game of life" is proposed. First the cluster head election mechanism based on the estimate of the node residual energy is optimized. Then the sleeping scheduling model based on "game of life" and communication of multi-hops which used its neighbor nodes as forwarding nodes are proposed. Network simulator version 2 simulation shows that the improved protocol effectively prolongs the survival time of the wireless sensor networks and increass the amount of data transmission. |
