Abstract
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.

A method of preventing overlap of multiple personal area networks (PANs) in a ZigBee network, the method performed by a first node included in a first PAN of the ZigBee network comprising:
- verifying whether overlap of the multiple PANs occurs by verifying packets received from neighbor nodes;
- identifying beacon information of a neighbor node that causes the overlap of the multiple PANs by gradually adjusting radio frequency (RF) transmission wave;
- and
- adjusting a communication range based on the beacon information.
A method of preventing overlap of multiple PANs in a ZigBee network, the method performed by a first node included in a first PAN of the ZigBee network comprising:
- determining whether a communication status of communication performed over the first PAN satisfies a predetermined communication standard;
- identifying beacon information of a neighbor node included in a different PAN that causes overlap with the first PAN by gradually changing an RF transmission wave, when the communication status does not satisfy the communication standard;
- and
- adjusting a communication range based on the beacon information.
A node capable of preventing overlap of multiple PANs in a ZigBee network, wherein the node is included in a PAN of the ZigBee network and comprises:
- a communication unit to perform transmission and reception of packets with neighbor nodes;
- and
- a node controlling unit to verify overlap of the multiple PANs;
- wherein the node controlling unit identifies beacon information of a neighbor node that causes overlap of the multiple PANs by gradually adjusting an RF transmission wave transmitted via the communication unit, and adjusting a communication range based on the beacon information.
