Abstract
Methods to detect rogue access points (APs) and prevent unauthorized wireless access to services provided by a communication network are provided. A mobile station (MS) reports to a serving AP the received signal strength (RSS) for all APs in the area it travels. The serving AP detect a rogue AP based on inconsistencies perceived in the RSS reports, assessed during the handover phase or whilst the communication is active.

A method for detecting a rogue access point (AP) in a wireless access network, comprising:
- computing, with a serving AP, a Voronoi diagram that partitions a plane corresponding to a service area into a plurality of convex polygons, each polygon including a generating point representing the location of an AP in said service area, and every point in a given polygon being closer to its generating point than to any other;
- and
- computing, with the serving AP, for each polygon a minimum distance and a maximum distance between any point of said respective convex region and each other generating point in the Voronoi diagram and storing said minimum and maximum distances.
