摘要
针对无线传感器网络节点密集和节点能量有限等特点,提出了一种簇头变化机制,数据业务节点使用指数退避算法来竞争本簇的簇头,而原簇头转入休眠状态。网络仿真结果表明该机制可提高能量效率和降低传输时延。
In wireless sensor networks, sensor nodes are distributed densely and the energy of nodes is always limited. A duster head transformation mechanism is proposed in the paper that the nodes with continuous data traffic use the exponential back off algorithm to oompete the new duster head in their local cluster and the former cluster head turns to the sleep mode. The simulation results show that the mechanism provides high energy efficiency and low latency.
