Router for ZigBee Networks
ZigBee networks can be configured to operate in a variety of different ways to suit the application and environment. Supported topologies include:
ZigBee nodes connect directly to each other for peer to peer communication
Using a single PAN coordinator, each node connects directly to the central coordinator – all inter-node communications are passed through the coordinator.


A cluster tree network consists of a number of star networks connected whose central nodes are also in direct communications with the single PAN Coordinator.
Using a set of routers and a single PAN coordinator, the network is formed into an interconnected mesh of routers and end nodes which pass information from node to node using the most cost effective path. Should any individual router become inaccessible, alternate routes can be discovered and used providing a robust and reliable network topography.
