Resource Allocation in D2D Networks with Location Based Distance Information

摘要

Recently, mobile internet traffic has rapidly increased as the huge increase of the smart phone and mobile devices. D2D (Device to Device) is known that it reduce the traffic load of the base station and also improves the reliability of the network performance. However, D2D has a problem that the efficiency decreases as interference is increased. In this paper, we propose a resource allocation scheme to use the resources efficiently when the D2D link share the resources of the cellular network in the uplink. D2D communication utilizes the location information for allocating resources when the eNB know the location of all devices. The proposed scheme not only ensures the performance of the D2D communication but also decrease the computational complexity Simulation results show that the proposed scheme attains the comparable throughput over optimal scheme with a very small computational complexity.
