Abstract
We analysed the opportunistic scheduling method in MMR proposed by Samsung Electronic Cooperation and confirmed the efficiency by simulation. We also investigated the relationship between the throughput and fairness under the proposed method. The main objective of this study is to propose an opportunistic packet scheduling method in MMR, which considers the QoS requirement of user. Using the simulation the performance of the proposed method is compared with those of i) pure opportunistic packet scheduling method which doesn't consider QoS requirement and ii) packet scheduling method which only consider the QoS requirement, but does not utilize opportunistic packet scheduling.
