Multi-tier ON/OFF Scheduling Algorithm for Small Cell Networks with Renewable Energy

In the future cellular network, densifying the multi-tier heterogeneous cellular network (HetNet) via viral deployment of small cell base stations (SBSs) can increase energy consumption. In order to solve the energy problem in the future, SBSs that rely solely on energy harvesting can be adopted. In this paper, we focus on problem about multi-tier ON/OFF scheduling of SBSs and the goal is to minimize the overall cost of the network, including energy consumption costs and transmission delay costs of a HetNet. Finally, simulation results show, proposed algorithm can improve the overall performance of the network.
