In this paper, we propose a Group-Oriented QoS-Enhanced proportional fair (GQPF) scheduling algorithm, which aims at maximizing QoS throughput while still retaining fairness as well as maximizing system throughput in downlink OFDMA networks. GQPF proposes a Group-Oriented QoS-enhanced PF-based utility function for multi-channel OFDMA networks. We demonstrate via extensive simulation results, that...
The packet scheduling problem has been deeply studied for lot of years by researchers in the computer science and telecommunications fields as an important solution that decides the order in which packets are sent over a link in order to provide QoS on a network. Recently, the packet scheduling has become again a challenging topic due to the massive use of wireless technologies (e.g. WiFi, LTE, 4G/5G),...
