Abstract

An important aspect of wireless networks is dynamic behavior. In this paper, we propose a joint cross-layer design for QoS (Quality of Service) content delivery. Central to our proposed cross-layer design is the concept of adaptation. We propose QoS-awareness scheduler and power adaptation scheme at both uplink and downlink Medium Access Control (MAC) layer to coordinate the behavior of the lower layers for resource efficiency. The test results show that our cross-layer design provides a good scheme for wireless QoS content delivery.
