FLOC: A Fast Local Clustering Service for Wireless Sensor Networks
نویسندگان
چکیده
We present a fast local clustering service, FLOC, that produces nonoverlapping and approximately equal-sized clusters. The clustering is such that all nodes within unit distance of a clusterhead belongs to its cluster, and no node m units away from the clusterhead may belong to its cluster. By asserting m ≥ 2 FLOC achieves locality: effects of cluster formation and faults/changes at any part of the network are contained within at most 2 units. By taking unit distance to be the reliable communication radius and m to be the maximum communication radius, FLOC exploits the double-band nature of wireless radio-model and achieves clustering in constant time regardless of the network size.
