Study of ZigBee Wireless Mesh Networks

ZigBee is the new standard that has been developed for low cost, low data rate and low power consumption wireless network. And mesh is a type of network architecture. This paper provides a brief overview of the available IEEE 802.15.4 topologies, and then delvesing the mesh topology, describing its advances, disadvantages and application, and presents a detailed study on open research issues in ZigBee mesh networks. Theoretical network Capacity and real capacity formulas influenced by coverage and response time are discussed, followed by analyzing the route discovery and route cost in detail. Finally, we introduce the security feature including trust center and security modes.
