Abstract


Based on the architecture of ZigBee wireless sensor network (WSN) and the hierarchical modeling mechanism of OPENT, an enhanced ZigBee simulation model was studied to improve the MAC layer process model of IEEE 802.15.4 protocol provided by OPNET. The ZigBee Protocolcompatible network layer protocol, the routing algorithm, and the network layer process model based on an embedded routing function of OPNET were designed, which enhanced the scalability of ZigBee simulation system. And the enhanced ZigBee model optimized the number of router nodes needed for nodes access network, network control overheads, and end-to-end delay under different network scales.
