Energy efficiency is a major design goal for resource-constraint Wireless Sensor Networks (WSNs). In this paper, an energy efficient clustering approach is employed to meet this design goal. Moreover, given the fact that most of the existing clustering algorithms do not address the hot spot problem that arises in the vicinity of the base station, an unequal clustering mechanism is implemented among nodes at different distances from the base station. In this way, the hot spot problem is mitigated by evenly distributing energy consumption in WSNs. We further use simulation to carry out performance evaluation and present analysis.
