Fast Re-association Scheme in Beacon-enabled Wireless Sensor Networks
Zigbee has been considered as a promising standard for wireless sensor networks. There are two recovery mechanisms when node is orphaned. Although an orphan realignment mechanism is provided in Zigbee, it is only suitable for orphaned node associating with the coordinator which has 64-bit physical address of the orphaned node, and not suitable for beacon enabled network. And the re-association mechanism is time consuming because there is a long delay for channel scan before association. In this paper, we propose a fast re-association scheme for beacon enabled network based on Zigbee, in which the passive channel scan is not needed before association. Orphaned node selects the coordinator which has the highest estimation value. Because the channel scan is not needed, the re-association delay could be reduced greatly.
