The density of IEEE 802.11 Wireless Local Area Networks, especially in metropolitan areas, has resulted in almost ubiquitous wireless presence in such environments. Apart from the benefits of increased wireless coverage, though, uncontrolled WLAN deployment has brought to attention interference issues among neighbor wireless networks. Combating interference has become one of the keys to successful wireless infrastructure management. To this end, network topology information, such as information about overlapping cell coverage and client presence is necessary input. The authors wish to exploit the spectrum sensing capabilities and inherent mobility of clients in order to gather a more up-to-date view of the network topology and a user-perceived view of interference conditions.
