Opportunistic scheduling for streaming services in HSDPA

Streaming technique, widely developed and used in the internet to convey multimedia application (e.g., audio, video clip, etc.), is supposed to occupy a large share of the third generation system bandwidth. Recently, studies are focused on the transmission of streaming services over High Speed Downlink Packet Access (HSDPA) system using time shared channels. In this case, the stringent QoS constraints of these services may result in a loss of HSDPA cell capacity if an appropriate scheduler is not used. In this paper, we propose a new opportunistic scheduler that allows to transmit streaming traffic over HSDPA without losing much cell capacity. Results afforded by this scheduler are promising and show that our proposed scheduler outperforms the existing scheduling algorithms.
