We consider opportunistic communication in multiservice wireless data networks using centralized controllers. Opportunistic scheduling (OS) is an emerging cross-layer media access control design approach to multiuser communication over fading wireless channels. OS exploits channel variations to maximize wireless throughput. We present a general background of OS schemes and then propose an OS scheme making an optimum trade-off between throughput and fairness, while maintaining stability in different channel environments and guaranteeing minimum service to multiple queues active concurrently at a given user.
