    Stochastic Sleeping for Energy-Conserving in Large Wireless Sensor Networks

    • 摘要: 调度冗余节点轮流工作能有效延长网络寿命,然而现有的调度协议需要地理位置信息,引入了额外负载.研究随机睡眠的节点调度机制,给出了4种基于不同信息的随机调度模式并分析比较其性能.结果表明,根据邻居节点信息合理设置节点睡眠概率可以不同程度地减少工作节点个数和保证较高的网络覆盖率.

       

      Abstract: Scheduling the nodes to work alternately can prolong the network lifetime efficiently. The existing solutions usually depend on the geographic information which may compromise the effectiveness as a whole. In this paper, a stochastic sleeping scheduling mechanism is studied and four stochastic scheduling schemes based on different information are introduced. Furthermore, analysis and simulation are provided in detail. The results show that stochastic sleeping scheduling mechanism can reduce the working node number and guarantee a high coverage rate in different level if the sleeping probability is set based on neighbors information properly.
