We study the channel allocation scheme for cooperation network with the aim of improving system throughput in addition to meeting QoS requirements. A suboptimal heuristic algorithm is proposed and implemented by using virtual nodes. The method simplifies joint channel allocation and cooperation by considering direct transmissions only. The proposed algorithm achieves adaptive allocation. Simulation results indicate
that the proposed algorithm significantly outperforms previous works in terms of system throughput and QoS.
Key words： cooperation; channel allocation; virtual node; QoS; throughput
