摘要: 针对无线传感器网络中数据包对时延的不同要求,提出一种时延受限的能量高效的路由算法(DCEER),在只有节点到节点一条传输路径且满足时延前提下,采用纯粹的节点到节点方式传输数据到Sink点,其他情况下选择满足数据包时延要求的最小超节点中继路由传输数据,即节点-超节点-Sink点。仿真结果表明,DCEER算法具有较长的网络生命周期和较短的时延,可实现能量高效利用和时延受限的平衡。

Abstract: Aiming at different data delay requirement in Wireless Sensor Network(WSN), a delay constrained energy efficient routing algorithm for WSN called DCEER is proposed. If this is the only path that has a delay smaller than or equal to the data delay requirement, then the message will be delivered by using the pure sensor-to-sensor path, otherwise the most energy-efficient path in terms of minimum number of forwarding sensors and the minimum total delay is selected, namely, by using sensor to supernodes to sink. Simulation results show that, DCEER has a longer network lifetime and shorted delay, it can balance the energy efficient and delay constrained.
