An analysis on guaranteed network lifetime for cluster-based wireless sensor network

Designing a wireless sensor network is very important to provide a guaranteed network lifetime where lifetime of the network is limited by the energy consumption of the individual nodes. One approach is to explore clustering idea to extend the network lifetime. Mhatre et al. provides a guideline for that while they have considered an infeasible situation by introducing circular shaped cluster to cover the whole area of interest without overlapping. In this paper we design it on the basis of regular hexagonal cluster. We also provide the performance comparison with circular cluster.
