A novel packet scheduling scheme in HSDPA via GEO Satellite

In this paper, we propose a novel packet scheduler for satellite high speed downlink packet access (S-HSDPA) air interface. We have considered a geostationary bent-pipe satellite for this work. Satellite systems are meant to complement the terrestrial access network to provide seamless global roaming and are expected to connect to the same core network. A cross-layer approach was used in designing the scheduler which uses both the channel state information (CSI) and the queuing factors while taking scheduling decisions. Our aim is to propose a packet scheduler that will ensure quality of service depending on traffic type, high utilization of resources and a fair resource allocation among users. The performance of our proposed scheme is compared with other scheduling schemes.
