Al-Janabi H. Mathematical models and two-layered method of the network resource allocation in the downlink of WiMAX technology

Object - processes of network resource allocation in the WiMAX downlink. Purpose - improving the quality of service through a balanced network resource allocation of the downlink in WiMAX technology. Methods - mathematical programming, set theory, teletraffic theory, optimization theory of multilevel hierarchical systems. Results - the mathematical model of resource allocation of the WiMAX downlink on the data link and network layers of the OSI model was firstly obtained; the mathematical model of frequency subchannels allocation in the Wi-MAX downlink have been improved; the hierarchical coordination method of resource allocation in the WiMAX downlink on the data link and network layers of the OSI model have been improved. It is introduced - in learning process in Odessa National Academy of Telecommunications named after O.S. Popov and Kharkiv National University of Radio Electronics; in the research work on "Improving the technology of construction and design methods of telecommunication networks using adequate mathematical traffic models". A patent received for the useful model. The field of use is telecommunication systems and networks
