PROJECT TITLE :

High Throughput Opportunistic Cooperative Device-to-Device Communications With Caching - 2017

ABSTRACT:

To achieve the potential in providing high throughput for cellular networks by device-to-device (D2D) communications, the interference among D2D links ought to be carefully managed. During this paper, we propose an opportunistic cooperation strategy for D2D transmission by exploiting the caching capability at the users to manage the interference among D2D links. We contemplate overlay inband D2D, divide the D2D users into clusters, and assign different frequency bands to cooperative and nonco operative D2D links. To provide high chance for cooperative transmission, we have a tendency to introduce a caching policy. To maximise the network throughput, we tend to jointly optimize the cluster size and bandwidth allocation, where the closed-kind expression of the bandwidth allocation issue is obtained. Simulation results demonstrate that the proposed strategy can offer four hundredpercent-five hundred% throughput gain over ancient D2D communications when the content popularity distribution is skewed and will offer sixty%-eightyp.c gain even when the content popularity distribution is uniform.
