无线传感器网络中基于非端到端的区分队列服务

摘要

In WSNs, one end of the application is the sink, the other end is not a single sensor node, but a group of sensor nodes. Traditional end-to-end QoS is unfit for WSNs. This paper proposed to provide different QoS for different event in WSNs based on a set of new non-end-to-end event QoS parameters. It chosen to provide event QoS in WSN using DQS. By using the strategy, the sink could detect the urgent event reliably and in time. The result of simulation verifies the effectiveness of our approach.%在无线传感器网络中,通信的一方是汇聚节点,通信的另一方不是某一个传感器节点而是一群传感器节点.适用于端到端通信的服务质量方法不再适用于无线传感器网络.为此,提出了一套新的非端到端的事件服务质量参数,并基于此提出了一种基于区分队列服务算法的、为网络中不同的事件提供不同服务质量的方法.通过这一策略,汇聚节点可以及时可靠地检测到待处理的紧急事件.仿真实验结果验证了该方法的可靠性.
