An efficient, fair, class based, delay jitter controlled packet scheduling algorithm for 4G broadband wireless access systems

摘要

A goal for next generation mobile networks is to provide seamless personal mobile communication and improved quality of service (QoS). Fair, class based service and lossless handoff are a focus for improving QoS. The research presented in this paper proposes a scheduling mechanism for providing improved QoS in mobile broadband Internet Protocol (IP) high-speed downlink packet access (HSDPA) networks. In order to reduce the handoff packet drop rate at the radio layer and to reduce the packet forwarding rate at the IP layer a new scheduling algorithm which is used at both IP and radio layer is proposed.
