Underlay Device to Device Networks Interference Modelling Radio Mapping and Resource Allocation

Abstract

The upcoming B5G and 6G networks envision an ultra-dense network with a newlinemultitude of devices running myriads of applications. Hence, increasing the net- newlinework capacity and the networked device density are the most prominent challenges newlinefor future wireless systems. In this context, Device-to-Device (D2D) communica- newlinetion is increasingly being realized as an important enabling technology. A D2D newlinenetwork augments the cellular network capacity and decreases the latency and the newlinecore network traffic by offloading local data traffic to direct links between the de- newlinevices, thereby increasing the spectral efficiency of the network. newlineApart from empowering local multimedia exchanges and message sharing, a newlineD2D network also enables several novel and upcoming applications like Machine- newlineto-Machine communication, Vehicle-to-Vehicle and Vehicle-to-Infrastructure com- newlinemunication, Healthcare and Body Area Networks, Gaming and Social Networks, newlineDistributed Storage Systems, Localized Advertising, and several ublic safety ap- newlineplications like Post-disaster Communication. newlineIn order to realize the full potential of D2D networks, several exciting and chal- newlinelenging problems need to be addressed, e.g., device discovery and pairing, com- newlinemunication mode selection, synchronization, and, most importantly, coexistence newlineissues, and interference management.
