Analysis of balancing process the subchannels number allocated to subscriber stations in WiMAX

Method of balancing the number of subchannels allocated to subscriber stations in WiMAX network based on solution of optimization problem associated with maximizing the lower level allocated bandwidth for each subscriber station according to its QoS requirements for access rate was investigated. Research of proposed method confirmed the adequacy of the model and effectiveness of solutions as a whole in terms of providing different types of service level (with and without guaranties) to subscriber stations. Results showed that in balancing the number of subchannels allocated to subscriber stations with a deficit of network resource adaptive reduction of provided level of quality of service performed dependently on the type of possible guaranties and requirements regarding the access rate.
