Fuzzy multiple criteria switch off method for dense heterogeneous networks

Abstract: The growth in mobile traffic demand is leading to a dense heterogeneous cellular network. This massive deployment of mobile equipment (i.e. base stations) may cause a high increment of the network energy consumption and therefore operational expenditure for operators. One of the most promising techniques to save energy (and costs) is to switch off some underutilized cells during off peak hours. In this line, our focus is to optimize the number of base stations in dense LTE pico cell deployments in order to max… Show more

“…An example of that can be found in [159], where the authors take advantage of RL to propose a decentralized Qlearning approach to allow energy savings by learning a policy by the iterations with the environment taking into account different aspects over time, such as the daily solar irradiation. Also, in [160], the authors switch off some underutilized cells during off peak hours. The proposed approach optimizes the number of base stations in dense LTE pico cell deployments in order to maximize the energy saving.…”

“…An example of that can be found in [172], where the authors take advantage of RL to propose a decentralized Q-learning approach to enhance this case of study. Also, in [173], the authors switch off some underutilized cells during off peak hours. The proposed approach optimises the number of base stations in dense LTE pico cell deployments in order to maximize the energy saving, they use a combination of Fuzzy Logic, Grey Relational Analysis and Analytic Hierarchy Process tools to trigger the switch off actions, and jointly consider multiple decision inputs for each cell.…”
