<strong>Zigbee</strong> Operation - II Forming a zigbee network by the coordinator Search for a suitable radio channel Start the network assigning a PAN ID to the network - can be predetermined or obtained dynamically Assigns itself the network id of 0x0000 Ready to respond to queries from other devices Join process by other nodes: Search for network: Scan the available channels and find operating networks (separated by their PAN IDs) Select parent: from (possibly) multiple routers and coordinator in range Send join request Accept or reject join request (by the coordinator/routers)
<strong>Zigbee</strong> Operation - III Message propagation: Message contains two destination addresses - Address of final destination, Address of next hop node Are any of these obvious for any network topology? Route discovery mechanism Route discovery broadcast is sent by parent router of source end device - Contains the network address of destination end device All routers receive the broadcast Parent router of destination end device replies back to parent router of source end device As the reply traverses back, the hop count and signal quality measure for each hop are recorded - Each router in the path can build a routing table containing best path to destination end device Eventually each router in the path will have entry in the routing table
