<p><b>Abstract</b>—We present a fast, local clustering service, FLOC, that partitions a multihop wireless network into nonoverlapping and approximately equal-sized clusters. Each cluster has a clusterhead such that all nodes within unit distance and some nodes within distance <tmath>m</tmath> of the clusterhead belong to the cluster. We show that, by asserting a stretch factor <tmath>m \geq 2</tmath>, FLOC achieves locality of clustering and fault-local self-stabilization: The effects of cluster formation and faults/changes at any part of the network are contained within at most <tmath>m+1</tmath> units. Through simulations and experiments with actual deployments, we analyze the trade-offs between clustering time and the quality of clustering and suggest suitable parameters for FLOC to achieve a fast completion time without compromising the quality of the resulting clustering.</p>
