Mobile stations localization in a WLAN

This paper proposes a localization protocol of mobile stations in a WLAN (wireless local area network). The originality of this protocol is made of two parts (i) we use an object-relational database and (ii) we use a semaphore channel devoted to localize mobile stations in access point coverage areas and in virtual coverage areas via near-to-near relays. The database manages the knowledge of the mobile stations related to the access points (roaming) and an historical record of the last moves of the mobile stations. This protocol was written in Java, we also used the JDBC (Java DataBase Connectivity) classes to interoperate with the database.
