| 摘 要： | 在基于低功耗自适应集簇分属协议将操作划分为轮的算法中,因轮长过大而导致的多数簇头轮内死亡是影响网络有效使用的重要问题。为有效地控制簇头轮内死亡的发生,提出了变长轮的思想,引入了能量预约法。为使能量预约法产生作用,其参数的确定必须满足多方面的制约因素。仿真结果表明一个优化的能量预约法增强了网络的可用性。

| Abstract: | A problem of death of cluster-heads in a round due to a long round duration is an important issue in routing algorithms based on LEACH in which an operation is divided into rounds，because the problem effects the networks’ usability.In order to deal with the problem，the authors introduce a variable round mechanism and an energy-reserved method in this paper.Parameters in the energy-reserved method must be satisfied for a number of constrained factors so that the energy-reserved method takes effect.The simulation shows that the optimal energy-reserved method enhances the usability of WSNs. |
