CTLinQ: Content-Centric Link Scheduling in Cache-Enabled Device-to-Device Wireless Networks

Abstract

In this paper, we consider cache-enabled device-to- device (D2D) wireless networks and propose a content-centric link scheduling method, called CTLinQ, to maximize the number of overall D2D links that can be simultaneously activated. Then, interference among different D2D links can be reduced and the quality-of-service (QoS) of each activated link can be guaranteed. Simulation results show that the proposed method outperforms the existing ones in terms of power consumption, the number of activated links, and overall system throughput in particular in high signal-to- interference-plus-noise ratio (SINR) region.
