Abstract:
Dense IEEE 802.11 networks require thorough radio network planning to minimize the detrimental effects of channel interference and achieve good performance. When multiple IEEE 802.11 networks operating under different administrations reside in the same geographical area (as defined by the bounds of radio signal transmission and reception), the problem of efficient radio resource allocation arises. Particularly, in highly populated urban environments, efficient radio resource allocation can be quite a challenge, due to the finite number of interference-free channels available in the IEEE 802.11 family of standards. To address this shortcoming, we have investigated how the radio resource management capabilities provided by the IEEE 802.11k standard can support a distributed approach in channel assignment. In this paper, we present our family of distributed channel assignment algorithms and elaborate on their pros and cons. Furthermore, we present our simulation environment for simulating distributed channel assignment scenarios based on the NetLogo agent modeling environment.
