TDCS: A new mechanism for automatic channel assignment for independent IEEE 802.11 networks

In the last few years, IEEE 802.11 applications has experienced a significant growth. This expansion creates scenarios where distinct administrators manage wireless networks. These scenarios lack of a unique authority to perform an adequate channel allocation that minimizes the performance degradation generated by medium access sharing and co-channel interference. This work proposes a new dynamic channel selection mechanism that focuses on the restrictions imposed by scenarios with independent IEEE 802.11 networks and adapts faster to the interference pattern variations. Besides, the performance of the new mechanism is evaluated and compared to others through simulations.
