摘要


采用休眠机制可以有效降低无线传感器网络的能量消耗,延长网络的生存时间.基于休眠概率与生存期的关系,建立节点休眠/唤醒机制的系统模型,给出无线传感器网络中节点状态间相互转换的2种基本模型,分析休眠概率与休眠轮次对无线传感器网络存活状态的影响.仿真结果表明,随着休眠概率与休眠轮次的增加,网络的生存期得到有效地延长. The use of dormancy mechanism can effectively reduce the energy consumption in wireless sensor networks, thereby extending the lifetime of the network.Based on the relationship between dormant probability and survival,this research builds a system model of sleep/wake-up mechanism and proposes two basic system models for the conversion of node status,and analyzes the mechanism of sleep/wake-up effects for the survival status of wireless sensor networks.The results of the simulation show that the lifetime of the network could be effectively extended with the increase of the sleeping probability and dormant rounds.
