Buffer-aided relay networks in 5G and beyond-5G mobile systems

Wireless communication in the 5G era has to meet challenging goals such as huge target data rates, ultra-low latency, massive connectivity, and several other requirements. In the literature, several techniques were suggested to fulfil these goals. One of the promising techniques to achieve higher data rates, which has received considerable attention recently,is buffer-aided cooperative relay networks.This thesis aims to study how to exploit buffer-aided relays in the 5G cooperative net-works more effectively to get closer to achieve the goals of the 5G and beyond. Specifically,the proposed techniques in this thesis are directed to improve the most critical performance metrics of the buffer-aided cooperative relay network: the system throughput, the diversity gain and the average packet delay.
