摘要： Disclosed is a method of preventing overlap of multiple PANs in a ZigBee network. According to the method of preventing overlap of multiple personal area networks (PANs) in the ZigBee network, a first node included in a first PAN of the ZigBee network verifies whether overlap of the multiple PANs occurs by verifying packets received from neighbor nodes, identifies beacon information of a neighbor node that causes the overlap of the multiple PANs by gradually adjusting radio frequency (RF) transmission wave, and adjusts a communication range based on the beacon information.

摘要： Provided is a method of managing addresses of incommunicable nodes in a ZigBee network, and more particularly, a method of managing address values of a plurality of nodes that form a ZigBee network by efficiently withdrawing address values from nodes which are incommunicable for reasons of abnormality. An address management process can be performed using two methods. According to a first method, a parent node withdraws address values of child nodes that do not transmit a hello message for a predetermined period of time. According to a second method, a parent node transmits a periodic or non-periodic request message to child nodes, and the child nodes, which receive the request message, immediately transmit a hello message to the parent node. Then, the parent node withdraws address values of child nodes that do not respond to the request message sent by the parent node more than a predetermined number of times. An address value assignment process and a process for nodes that have their address values withdrawn are also provided.
