Security Providing To Wireless Sensor Networks by Presence of Location Monitoring Systems

摘要

Due to technological advances in sensor technologies, wireless sensor net works are widely used for location monitoring. In such systems monitoring personal locations is done through Internet server. As the server is untrusted, it may cause threats pertaining to privacy of individuals being mo nitored. This is the potential risk to be addressed. This paper presents two algorithms to address this problem. These algorithms achieve two purposes. The first one is that they can improve quality of monitoring locations while the second one is for location anonymization so as to preserving personal location privacy. The first algorithm is resource-aware which is aimed at reducing computational and communicational cost while the quality-aware algorithm is aimed at improving the quality of monitoring locations. Both are having a feature that preserves personal location privacy. The system is evaluated with simulation experiments using NS2.The empirical results revealed that the proposed system can provide high quality monitoring besides preserving personal location privacy
