Abstract :
This paper proposes a novel Frequency Time scheduler, called Frequency Time Scheduler with Delay Constraints (FTSDC), in order to handle streaming traffic in OFDMA (Orthogonal Frequency Division Multiple Access) system. 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 bandwidth in future wireless systems (e.g. WiMAX, LTE ldquoLong Term Evolutionrdquo, etc.). The stringent QoS constraints of these services may be reached at the expense of the system capacity and therefore a trade off between Fairness and capacity should be achieved. The novel opportunistic scheduler proposed in this paper balances this trade off and allows thus OFDMA systems to handle streaming services without losing much cell capacity. Results afforded by this scheduler are promising and show that it outperforms the existing scheduling algorithms.
