Adaptive Cross Layer Scheduling with Flow Multiplexing

Wireless communications has emerged as one of the largest sectors of the telecommunications industry and one of the most promising growth areas into the next decade. To meet the challenges of deploying an efficient wireless multimedia network, it is useful to consider the various open systems interconnection (OSI) layers together when designing the network to take into account quality of service (QoS) requirements at the medium access control (MAC) layer where the scheduling and resource allocation algorithms reside. In this paper, we propose and evaluate an adaptive cross layer (physical, MAC and application) scheduling policy with flow multiplexing to fairly meet intra-user and inter-user QoS requirements.
