Recent years have witnessed increasing interests in passive intrusion detection for wireless environments, e.g., asset protection in industrial facilities and emergency rescue of trapped people. Most previous studies have focused primarily on exploiting a single intrusion indicator, such as moving variance, for capturing an intrusion pattern at a time. However, in real-world, there are many intrusion...
To support emerging pervasive computer applications, efficient data access and information sharing is essential in mobile wireless environments. The data-centric storage approach provides energy-efficient data dissemination and organization. However, wireless devices have limited storage and are energy-constrained. To address these issues, we introduce the concept of content caching networks, in which...
Wireless spoofing attacks are easy to launch and can significantly impact the performance of networks. Although the identity of a node can be verified through cryptographic authentication, conventional security approaches are not always desirable because of their overhead requirements. In this paper, we propose to use location information, a physical property associated with each node, hard to falsify,...
