Book excerpt: Abstract: The work here proposes a framework for resource-allocation in mobile worldwide interoperability for microwave access (WiMAX) networks with quality of service (QoS) support that aims to balance between service provider's revenue and subscriber's satisfaction. Since a better optimization can be achieved with the exchange of information across protocol layers, a cross-layer design approach is followed to efficiently utilize the scarce radio resources available to Mobile WiMAX networks. In particular, the thesis presents a resource-allocation algorithm at the physical (PHY) layer that supports multiple connections with diverse service classes and QoS requirements. The algorithm prioritizes each connection bases on the QoS requirements (for example the required minimum data rate and maximum latency), queue status, and channel condition of every connection. Resources are then allocated in a way that maximizes the system throughput while meeting the overall transmit-power constraint and QoS guarantees, and ensuring fairness among users. The algorithm is shown to provide a performance that is comparable to the maximum system throughput approach which does not support QoS or fairness.
