Zigbee is a kind of wireless network susceptible to interferences. Network reliability is one of the key elements for the entire network. Zigbee networks have been widely used in many fields such as agriculture, medicine, traffic and environmental protection. The larger the net-work is, the more complex the environment of network will be, and the more problems will be caused. There are some typical problems, such as the network disconnection caused by inter-ferences, route errors in communication, the irrationality of network topology, data conges-tion appears in the central node of a mesh network. These problems are all caused by the instability of network topology eventually. This paper proposes a Zigbee network model used to large-scale networking. The network model maintains a relatively stable network topology, plans the data flow on network links reasonably, and offers protection for reliable network communication.
