Energy being major constraint and data gathering the core operation, considerable attention has been given to energy efficient data gathering in wireless sensor network research and clustering has emerged as an efficient architecture to achieve it. Low Energy Adaptive Clustering Hierarchy (LEACH), proposed in past, guided significant portion of this research and is used as a benchmark in this area. However, use of probabilistic and randomized approach for cluster-head selection results in their variable number, during different rounds of data gathering.
