    Formulating and Solving Problem of Priority Subchannel Allocation in Downlink WiMAX
    (2016) Al-Janabi H. D.; Al-Janabi H. D.; Hojayev O. M.
    Model of priority subchannel allocation in downlink WiMAX presented. Model based on solution the optimization problem associated with maximizing the lower weighted level allocated bandwidth for each subscriber station according to its QoS requirements for access rate and priority. Numerical research of proposed model confirmed the adequacy and effectiveness of solutions as a whole in terms of providing different types of service level to subscriber stations depending on the priority.

    Priority Based Balancing Model of Resource Allocation in LTE Downlink
    (©Scholars Academic and Scientific Publisher, 2016) Лемешко, О. В.; Aymen Al-Dulaimi
    Investigation of priority based balancing model of resource allocation in LTE downlink supporting RAT 1 presented. The novelty of model is that it can be used to describe the process of resource blocks allocation in LTE downlink given user equipments requests priority. Using the model allows to optimize the process of resource allocation in LTE downlink in solving the problem by mixed-integer linear programming. The advantage of the model is that the balancing of resource blocks number allocated to each of user equipments is performed based on QoS requirements: demanded bit rate, priority and resource type (with or without guarantee). Results of research confirmed the efficiency of model and adequacy of obtained on its basis solutions.

    Priority-Based Model of Subchannel Allocation in WiMAX Downlink
    (©Scholars Academic and Scientific Publisher, 2016) Лемешко, О. В.; Haider D. Al-Janabi; Hussam D. Al-Janabi
    Priority-based model of subchannel allocation in WiMAX downlink is presented, which is based on solution of the optimization problem associated with maximizing the lower weighted bound of allocated bandwidth for each subscriber station according to its quality of service requirements for access rate and priority. Numerical research of model showed that increasing of the bandwidth requirements of the stations with higher priority significantly affect the resource allocation to other stations than the requirements of lower priority stations. The adequacy and effectiveness of solutions in terms of providing different types of service level to subscriber stations depending on the priority is confirmed.

    Research of Factors Influencing the Subchannel Allocation to Subscriber Stations in WiMAX
    (2015) Лемешко, О. В.; Hailan Ahmad; Al-Janabi Haider Dheyaa Kamil; Hojayev Oraz
    Model of subchannel allocation in WiMAX network based on solution the optimization problem associated with maximizing the lower level allocated bandwidth for each subscriber station according to its quality of service requirements for access rate was investigated. Research of proposed model confirmed the adequacy and effectiveness of solution in terms of providing different types of service level (with and without guaranties) to subscriber stations. Results showed that 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.
