In the past few years mobile healthcare has attracted a lot of attention from both industry and academia. Medical sensors are usually attached to or implanted inside patient body. Since sensing results of BAN can directly impact the control of medical equipment, the authenticity and integrity of sensing data is essential for safety of patients. Existing research focuses on differentiating on-body...
Previous research on physical layer network coding (PNC) focuses on the improvements in bandwidth usage efficiency. In this paper, we propose a PNC-based node localization mechanism. When two signal sequences collide at the receiver, the starting point of collision is determined by the distances between the receiver and senders. When the signal interference results from two receivers are combined...
Research shows that location based routing can improve the performance and efficiency of communication in mobile ad hoc networks. From another point of view, disclosure of location information can cause a serious privacy risk, especially in environments where different groups of nodes cannot fully trust each other. In this paper, we propose a protocol through which a wireless node can achieve configurable...
