基于QoS的无线传感器网络感知调度协议

QoS-based sensing scheduling protocol for wireless sensor networks

针对大规模随机部署传感器网络的节点密度不均匀性和不同应用对事件监测时延的不同需求,为提供全网可调的监测时延保障,设计了面向事件监测应用的全网能耗均衡的自适应分布式感知调度协议(ADSSP),仿真结果表明:相对于随机感知调度协议,ADSSP能获得更低的平均监测时延,在满足相同的平均监测延迟的前提下延长了30%的网络生存时间。

To satisfy the requirements of event detected latency according to different applications with unbalanced node density in randomly deployed large-scale wireless sensor networks,an adaptive distributed sensing scheduling protocol（ADSSP） which adaptively adjusts the duty cycles of sensor nodes based on node density and balances the energy consumption among sensor nodes was proposed.Compared with the random scheduling protocol,ADSSP can provide guaranteed lower average detection latency and also prolong the network lifetime up to 30 percent under the same situation.
