Abstract

During recent years the number of WiFi networks has experienced rapid growth. The evergrowing
number of wireless communications systems have made the optimal assignment of a limited
radio frequency spectrum a problem of primary importance. With the common 802.11 wireless
technology, few non-overlapping channels are available, and there is no standard mechanism for
the access points to dynamically select the channel to be used in order to minimize interference
with other access points. This has resulted in a situation where many WiFi networks use default or
suboptimal channel assignments, leading to poor performance, and uneven spectrum usage. In this
paper, we introduce three different approaches for the frequency assignment problem based on graph
coloring that can significantly improve frequency distribution and reduce the number of collisions in
the network.
