Fig. 1. Example of the clustering process.
Fig. 2. Cluster formation.
Fig. 4. Role assignment fusing multiple clusters: the notation aðb;cÞ used to label the nodes represents the distance table of each node, which means that node a is b hops from the sink, and c is the sum of the distances (aggregated coordinators-distance)
Fig. 5 depicts the role-migration process. In the initial role assignment (Fig. 5a), node B becomes the coordinator and nodes D, E, and F become collaborators
