  • This paper propose a QoS-aware resource allocation algorithm for cooperative relay-based OFDM cellular network with mixed services of different QoS requirements. The proposed algorithm solves relay selection, subcarrier allocation and power control issues. The design of resource allocation is formulated as a non-linear combinatorial optimization problem, which aims at maximizing the system sum utility while considering the data rate requirements of QoS users and the transmit power constrains for the base station as well as each relay station. To reduce the computational complexity, the global optimization issue is decomposed into subcarrier allocation and power control sub-issues. Numerical results demonstrate that the proposed algorithm is able to improve significantly the network performance in terms of power saving, system utility and system throughput.
