Abstract:
=======

For IEEE 802.11 wireless LANs (WLAN) with multiple access points (AP), it is critical to allocate the limited number of radio channels dynamically and efficiently.

This talk presents a new framework for the radio channel allocation (RCA) strategy for WLANs with multiple data rates to support multimedia traffic. First, we formulate the RCA as a min-max optimization problem regarding channel utilization with constraints of transmitting power and date rates. Second, we derive an expression to evaluate the channel utilization, which incorporates the condition of wireless channel, such as signal-to-noise (SNR) ratio and transmitting power, in addition to the transmitting probability of a station. Third, we propose a new RCA algorithm that considers both link adaptation and power control mechanisms, in addition to the impact of co-channel interference (CCI) and multiple date rates, which have not been considered by the existing RCA schemes.
