Abstract:
To meet the high reliability and real-time transmission needs of industrial monitoring Wireless Sensor Network(WSN), an improved hierarchical Collection Tree Protocol(CTP) called MM-CTP is proposed. The link-layer Markov chain analysis model for the IEEE 802.15.4 WSN is built. The link-quality estimation method of the CTP is improved to calculate routing gradient value and setup the routing hierarchy. The MM-CTP is implemented on the TinyOS and runs on TinyOS mote SIMulator(TOSSIM) simulation platform. Experimental results show the MM-CTP satisfies the reliability and real-time requirement of industrial monitoring network.

摘要: 根据工业监控无线传感器网络(WSN)的可靠性和实时性需求,采用跨层优化方法,提出一种基于介质访问控制层Markov模型的汇聚树协议MM-CTP。利用IEEE 802.15.4 WSN链路层动力学Markov模型对单簇网络进行数据帧传输性能分析,改进汇聚树协议的链路质量评估方法,通过计算最优路由梯度,建立网络拓扑,在保证较高数据到达率的同时,使网络延迟最小,以满足工业监控网络的数据传输需求。
