Base station is a major node for communication network's energy consumption.The accurate calculation of the energy-saving amount for the base station under EPC model is a technology bottleneck in this field.This paper proposed a modeling method of energy consumption of the base station based on particle swarm optimization(PSO)and least squares support vector machine(LSSVM)of sliding window,oriented at three kinds of typical scenarios base station.In this approach,a sliding window was established by selectin...
