Abstract:

Avoiding interferences and collisions among signals of beacons is the one of important issues to indoor location system for wireless sensor networks. Exclusive communication that makes only one beacon transmits its signals at one time can be utilized to resolve it in centralized architecture; and another effective beacon can be selected randomly as a center node in exclusive mode by current beacon leaving its exclusive state. Combining advantages of centralized and decentralized architecture helps to resolve the problem among signals interferences and collisions of different beacons effectively.

Key words: wireless sensor networks (WSN), indoor location, exclusive communication
