Access Point Location and Trajectory Tracking Method based on the Weight Update

Journal of Networking Technology Volume 5 Number 3 September 2014 ABSTRACT: In recent years, wireless access technology is quite popular for its convenience, fast and flexible. However, due to the openness of wireless network, this technology also faces with a number of secure challenges, one of which is how to deal with the unauthorized access point effectively. As we all know, the unauthorized access point leads to not only increasing interference between signals induced by the fierce competition of wireless channel resources, but also data leakage resulting in “wireless phishing”. In response to these security threats, much importance has been put on the research of unauthorized access point location and trajectory tracking. This paper firstly proposes an optimization model of wireless signal propagation. Then an access point location and tracking method called APL_T is put forward, which supports three-dimensional location based on the weight update improving the location accuracy effectively and raises the trajectory tracking of the access point in the light of the three-dimensional location. Finally, the experimental results show that APL_T has a high accuracy and can meet practical requirements.
