With the rapid advance of computer and network technology, more and more applications are deployed in the customer-side network. These applications require different quality of service (QoS), but have to share a few bandwidth limited Internet connections. Owing to the IP network's best-effort delivery mechanism, the QoS requirements are hard to be satisfied. There have been plenty of QoS solutions...
Next generation mobile radio networks of IMT Advanced systems family will offer ubiquitous broadband high area coverage, at up to 1 GBit/s in cities and 100 MBit/s in rural areas and QoS support in terms of throughput and low delay. Candidate technologies like 3GPP-LTE, WiMAX, as well as the WINNER system design are based on OFDMA transmission for flexible radio resource allocation, scalable and adaptable...
