High Throughput Opportunistic Cooperative Device-to-Device Communications

Abstract

In this paper, we endorse an opportunistic cooperation approach for D2D transmission with the aid of exploiting the cachingcapability on the users to govern the interference amongst D2Dhyperlinks. We recall overlay inband D2D, divide the D2D usersinto clusters, and assign specific frequency bands to cooperativeand non-cooperative D2D hyperlinks. To provide the excessive possibilityfor cooperative transmission, we introduce a caching policy. Tomaximize the network throughput, we collectively optimize the clusterlength and bandwidth allocation, in which the closed-shape expressionof the bandwidth allocation element is received.
