Abstract

In this paper, we aim at solving the co-channel interference (CCI) between cells in heterogeneous networks (HetNets), employing an interference-aware channel segregation based dynamic channel assignment (IACS-DCA). To improve the energy efficiency in HetNet, a distributed ON/OFF switching algorithm for BSs is proposed in which each BS selects ON/OFF strategy using game-theory. We combine these two algorithms by using the beacon signal. The beacon signal contains the traffic load information to be used for user equipment (UE) association when BS ON/OFF algorithm is employed and it is used for measuring the instantaneous beacon signal in IACS-DCA. We show by computer simulation that by combining IACS-DCA and distributed ON/OFF switching algorithms for BSs, high transmission quality is achieved.
