Energy-Efficient Clustering in Wireless Sensor Networks with Spatially Correlated Data
Ali Dabirmoghaddam, Majid Ghaderi, Carey L. Williamson · 2010
In this paper, we show how spatial correlation in data can be exploited to reduce energy consumption in a wireless sensor network. We analytically characterize the optimal cluster size, and then use a greedy clustering algorithm to study approximate solutions to the optimal data gathering problem.
