Abstract
We propose a set of resource allocation strategies for quality-of-service (QoS) provisioning over the wireless relay networks. By integrating information theory with the concept of effective capacity, our proposed strategies aim at maximizing the relay network throughput subject to a given delay QoS constraint. Applying the time division multiple access (TDMA) and frequency division multiple access (FDMA) to the relay networks, we develop the static and dynamic time/bandwidth allocation strategies with constant power. The simulation results show that our proposed strategies can significantly improve the effective capacity as compared to the conventional equal time/bandwidth allocation strategies. We also observe that the relay location can impact the improvement of the effective capacity, and the FDMA based scheme outperfoms the TDMA based scheme.
