摘　　要：针对应用于环境监控的无线传感器网络既要处理时间敏感的紧急事件又要延长网络寿命这一矛盾,提出了一种基于无线传感器网络的紧急节点群通道机制,它使多个相邻的紧急节点组成紧急节点群并对其建立高速群通道,同时对通道外的节点休眠。通过NS2进行仿真验证,结果表明该方案具有延时低、节能的特点,在提供有效的通信能力的同时还达到了节能的目的,具有较重要的工程应用价值。In order to solve the contradiction of time-sensitive events and energy efficient for environmental monitoring in wireless sensor networks, a new developed mechanism called nodes group corridor for urgent data transmission is proposed in this paper, which is to group the urgent neighboring nodes and create a corridor for them as well as to make others nodes be in saving energy mode. Simulation results in NS2 show that this mechanism with low latency and energy-saving features has important engineering value.
