Description The results of development a mathematical model for capacity allocation downlink
technology WiMAX. The novelty of the proposed model is possible preventive limit
transmission rate allocated to the service flows of the user stations in the downlink by
using the WiMAX technology linear or linear-quadratic objective function. It is shown
that the use of a linear-quadratic objective function in comparison with the linear, can
produce a more equitable management of requests based on the relative priorities. The
analysis of known methods for dividing the time-frequency resource WiMAX technology
showed that they all focus on the distribution between the subscriber stations all
bandwidth downlink. The model proposed is directed to the allocation of each user station
a guaranteed bit rate in the absence of overload downlink as well as the preventive
rate limiting allocated user stations under overload conditions. Using the mathematical
model is directed to distribution between subscriber stations of a time-frequency resource
of the downlink, which in turn improves the conditions in the electromagnetic
frequency range used. The influence of the priority request rate used in the model, the
nature of the possible failures.
