This paper derives an algorithm for minimizing energy spent by a hierarchical wireless sensor network in transmitting data to a sink, referred to as a base station. The network model considered is a single-hop multi-level clustered network. We draw on results from stochastic geometry to analytically determine the optimum number of clusters at each level. We show, both analytically and by simulation results, that a multi-level approach can significantly reduce the required network energy.
