Most of the QoS-based routing schemes proposed so far focus on improving the performance of individual service classes. In a multi-class network where high priority QoS traffic coexists with best-effort traffic, routing decision for QoS sessions will have an effect on lower one. A mechanism that allows dynamic sharing link among multiple classes of traffic(More)
traffic and may also decrease the throughput of the whole network. Abstract— Future communications networks are expected to support applications with quality of service (QOS) requirements. Supporting QoS poses major challenges due to the large size and complex structure of networks. Several studies have addressed different aspects of QoS routing. In this(More)

Nowadays the radio interface of several standards is enhanced with advanced technologies such as OFDMA and extension technology such as relay. By using those promising transmission technology for the next generation wireless communications, scheduling problem becomes more crucial and challenging. In our work, we aim to maximize the overall system capacity(More)
