Beacon scheduling system and method for preventing beacon overlapping |
摘要 |
Provided are a beacon scheduling system and method for preventing beacon overlapping in a ZigBee network including routers each with a beacon slot number according to a specific time slot. The system includes: a first router periodically transmitting beacons at a beacon interval according to a specific time slot; and a second router finding the beacon interval by scanning the beacons transmitted by the first router and transmitting beacons within the beacon interval in consideration of a superframe period for transmitting data. When a router in a sensor network operates, the router can efficiently select the beacon transmission time, and a sink node manages beacon overlapping between all the routers. Therefore, stable, low-energy consumption, and excellent performance sensor networking environments can be established in a beacon mode. |
