In this paper, we focus on the problem of constructing an information gain model for stroke prevention in Ubiquitous Healthcare (U-Health) Wireless Body Area Networks (WBANs). We have constructed an information-based probabilistic relation model among the key indicators and sequenced their data gathering priority and precedence in the WBAN. Then, we constructed a cost function over the energy expenditure...
An integrated location algorithm using satellite location and wireless sensor networks (WSN) is put forward to solve the issues of seamless location both indoors and outdoors in a pervasive computing environment in this paper. Pseudorange observation data of global positioning system (GPS) and distance observation data of WSN are utilized to carry out positioning. Simulation results show that comparing...
Traditional global positioning system (GPS) is not suitable for indoor location environments. A wireless sensor network (WSN)-aided GPS location algorithm is put forward in this paper in order to realize seamless connection between indoor and outdoor locations and shorten search and acquisition time of GPS signal. The algorithm utilizes auxiliary location information obtained from GPS reference station...
