一种快速可靠的无线传感器网络路由

针对无线传感器网络的特点,本文提出了一种快速可靠的无线传感器网络路由,采用建立网络树结构方式,使各节点拥有唯一的传输路径,降低网络延迟,减少能量消耗。该路由对硬件无特别要求,仅采用普通射频芯片即可以同时工作于任务查询方式及事件驱动方式,并具有较强的路径自我修复能力。算法通过软件仿真并与经典的路由协议Directed Diffusion做多方面比较,结果表明,该路由具有更好的性能,兼备低延迟,低功耗、鲁棒性强及易实现等特点。

Fast and reliable routing for wireless sensor networks

Based on the characteristics of the wireless sensor networks,this paper presents a fast and reliable protocol(FRP),which building the hop tree to make the nodes having the unique path so that to reduce network delay and energy consumption.FRP don't require special hardware,and can meet the requirements of query-based,event-driven,path recovery with the common RF chip.FRP is implemented by simulation and compared with the directed diffusion paradigm.Experimental results show that FRP has the better performance with low latency,low energy and high reliability.
