A Genetic Algorithm Based Cell Switch-Off Scheme for Energy Saving in Dense Cell Deployments
The energy consumption of mobile networks is rapidly growing; operators have both economic and environmental incentives to increase the energy efficiency of their networks. One way of saving energy is to switch off cells during periods of light traffic. However, cell switch-off is a difficult problem to solve through conventional optimization; existing research makes various assumptions to simplify the problem and offers some heuristics to solve it. The problem can be constructed in different ways depending on the system model that is chosen.
