Abstract Clustering is an efficient method for increasing the lifetime of wireless sensor network systems. The current clustering algorithms generate clusters of almost equal size. This will cause hot spot problem in multi-hop sensor networks. In this paper an energy efficient varying sized clustering algorithm EEVSCA and routing protocol are introduced for non-uniform node distributed wireless sensor network system. EEVSCA helps for the construction of clusters of varying size at the same time unequal cluster based routing algorithm forces each cluster head to choose node with higher energy as their next hop. The unequal size of clusters can balance the energy consumption among clusters. Theoretical analysis and simulation results show that EECSVA balance energy consumption well among the cluster heads and increase the network lifetime effectively.
