Development Results the Model Distribution of Troughputh in the WiMAX Mesh-Network
(KHARKIV NATIONAL UNIVERSITY OF RADIO ELECTRONICS, 2015) Harkusha, S.; Harkusha, O.; Ievdokymenko, M.
The frequency resource distribution mathematical model is offered as a problem of subchannels’ number balancing between radio channels formed by mesh- stations of the wireless network. The use of the offered model has made it possible to raise efficiency of the wireless mesh- network as a whole and ensure the “bottlenecks” absence.
Research of Influence Flow Characteristics to Network Routers Queues Utilization
(2016) Lebedenko, T.; Ievdokymenko, M.; Ali Salem Ali
Research results of the influence flow characteristics to network routers queues utilization were presented. It is determined that the use of the steady state estimations when calculating the average queue length is possible only after the end of transient process. Otherwise, it is advisable to use a more accurate differential model. Results of analysis showed that the duration of transient process is influenced by such factors as flow rate, capacity of the router interface, service discipline, etc. Within this research it was shown that the use of non-linear differential model can improve the accuracy of calculation of the average queue length, depending on the state of interface and selected service discipline.
