Mobile information services will play an important role in our future work and private life. Enabling mobility in urban and populous areas needs novel techniques for individual traffic planning. However, though there already are WAP-based traffic systems featuring route planning, their usability is not often universal. We present a SMS-based urban public traffic information system (SMS-UPTS) offering...

Recently, the open mobile alliance (OMA) has been set to define open DRM technologic specifications to protect copyrighted content against piracy, unauthorized use and distribution over mobile networks. This paper proposes an efficient OMA DRM v2.0 ROAP for protecting a rights object for a device. Our proposed ROAP can offer a more efficient DRM system for future mobile networks.
Location based service (LBS) cannot be realized unless the location of the user is available. For indoor LBS, indoor positioning must be utilized and many researchers have been working on indoor positioning and tracking. For example, extended Kalman filter (EKF) was exploited in Bluetooth based indoor positioning. Nowadays, WLAN (wireless local area network) is available virtually everywhere. Thus,...
Extended Kalman filter (EKF), which has long been used in the field of GPS positioning, has recently been used for indoor positioning, introduced extended Kalman filter (EKF) indoor positioning method based on Bluetooth signal strength. However, the error range of the EKF is so large when it was applied in WLAN tracking that we modified it to use K-NN method for the measurement of the EKF. Furthermore,...
