The IEEE 802.16j WiMAX is designed to provide a broadband multi-hop wireless access. However traffic transmission in such networks faces the challenges of user demand differentiation, link congestion and network status variation. To tackle those issues we construct effective schedulers implemented at each RS to achieve the desired end to end flow control and congestion control over the whole network...
IEEE 802.16 technology has emerged as a competitive alternative to wireline broadband access solution. IEEE 802.16 can provide quality of service (QoS) guarantees for heterogeneous classes of traffic with different QoS requirements. The standard, however, leaves open the resource management and scheduling issues, which are crucial components to guarantee QoS performance. The main objective of this...
The provision of data services in 3G systems requires spectral efficiency solutions to increase the capacity of the radio access network as well as support for high data rates. In this context, the 3GPP introduces a new feature in the release 5 specifications denominated high speed downlink packet access (HSDPA). The HSDPA concept appears as an umbrella of features to improve both user and system...
