Interference Mitigation in D2D Communication Underlying Cellular Networks: Towards Green Energy

Device to Device (D2D) communication is emerging as a new participant promising technology in 5G cellular networks to promote green energy networks. D2D communication can improve communication delays, spectral efficiency, system capacity, data off-loading, and many other fruitful scenarios where D2D can be implemented. Nevertheless, induction of D2D communication in reuse mode with the conventional cellular network can cause severe interference issues, which can significantly degrade network performance. To reap all the benefits of induction of D2D communication with conventional cellular communication, it is imperative to minimize interference's detrimental effects. Efficient power control can minimize the negative effects of interference and get benefits promised by D2D communication. In this work, we propose two power control schemes, Power Control Scheme 1 (PCS 1) and Power Control Scheme 2 (PCS 2), to minimize the interference and provide performance analysis. Simulation results observe improvements with PCS 1 and PCS 2 as compared to without using any power control scheme in terms of data rate in both uplink and downlink communication modes of Cellular User Equipment (CUE).
