Offloading in Energy Harvesting enabled cellular Networks

Offloading and energy harvesting are two important methods in the cellular communication. Offloading decreases the load on the mobile network and improves the network capacity and coverage. On the other hand, harvesting the energy from the radio frequency (RF) energy causes the devices to consume less battery and consequently prolongs the user equipments (UEs) usage. In this paper, we offer a new approach to offloading and energy harvesting in cellular networks (CNs). In our scheme, users are divided among base station (BS) and local access point (LAP) to get service. A UE is connected to BS or LAP based on their channel conditions. We formulate our resource allocationscheme as an optimization problem and solve it using dual Lagrange approach. Our simulation results show the impact of various parameters on the increase or decrease of the total sum rate of our considered model
