Abstract
As a new wireless network architecture, Device-to-Device (D2D) wireless caching network has the advantage of high spectrum utilization and thus attracts more and more attention. In this paper, a square cell is used as a scenario. Under the condition of a new protocol model that avoids the inter-link interference, an effective method for D2D link scheduling in a cell is proposed. We divide the D2D link scheduling problem into two sub-problems: potential link pairing and the interfering link removal. The scheduling algorithm avoids the use of an exhaustive algorithm with unacceptable time complexity to discover an optimal D2D link matching. The simulation shows that the average user throughput of D2D wireless caching network based on the link scheduling algorithm is greatly improved compared with traditional wireless networks.
