The unique characteristics of wireless networks, namely the time varying channel conditions and multiuser diversity necessitate new scheduling solutions to be developed. The wireless resource is scarce and the mobile users perceive time varying channel conditions. To effectively harness the precious resource and achieve higher network performance, good scheduling schemes opportunistically seeking to exploit channel conditions is absolutely essential. The prime objective of this work is to improve system performance (e.g. throughput, capacity) under various fairness and QoS constraints. Simulation analysis of the proposed scheme is carried out under both TDMA and CDMA environments. As expected the obtained results prove to have higher throughput satisfying per user QoS constraints in both environments. In addition to this, system capacity and resource utilisation are considerably improved. Hence, this channel-based scheduler offers a substantial system gain, which is the basic requirement in a multiuser wireless scenario. However, a trade off always occurs between system throughput and user fairness.
