Cross-Layer Scheduler Design with QoS Support forWireless Access Networks

Scheduling plays an important role in providing quality of service (QoS) support for multimedia networks. We propose a cross-layer scheduler at the medium access control (MAC) layer for multiple connections with diverse QoS requirements, where each connection employs adaptive modulation and coding (AMC) scheme at the physical (PHY) layer. Each connection is assigned a priority, which is updated dynamically based on its channel and service...
