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.Experimen...
