Resource Allocation in Cellular Network with Device to Device Communication

Abstract

As advanced cellular technologies headway, more than one component carrier can now be jointly utilized in a base station. In this model the base station (BS) can utilize secondary carrier component (CC) which is D2D when the traffic is relatively high. In this paper , we study resource allocation in cellular network with device to device communication , which is deemed as a promising technique to improve the spectrum usage efficiency and alleviate the heavy burden on backhaul links Most previous works ignored user mobility, thus having limited practical applications. Here we utilize the user mobility pattern by the inter contact times between the users and propose a time -efficient greedy algorithm which has an approximation ratio as 1/2 .
