— In this paper, we address the problem of joint channel assignment, link scheduling and routing for throughput optimization in wireless networks with multi-radio and multi-channels. We mathematically formulate this problem by taking into account the interference, the number of available radios the set of usable channels and other resource constraints at(More)
—OFDMA resource allocation algorithms manage the distribution and assignment of shared OFDMA resources among the users serviced by the basestation. The OFDMA resource allocation algorithms determine which users to schedule, how to allocate subcarriers to them, and how to determine the appropriate power levels for each user on each subcarrier. In WiMAX, the(More)
