Adaptive Resource Allocation for WiMAX

The mobile WiMAX (standard 802.16e) provides capabilities for adaptive radio resource allocation for users with a slowly changing channel. To achieve a performance gain possible under adaptive allocation it is important to choose an appropriate practical algorithm feasible for real-time implementation. In the paper the allocation task is considered as a two-step process and several combinations of algorithms for each step are proposed. Performance of algorithms is evaluated on a WiMAX model with a variable bit rate traffic.
