Service gateways (SGs) are a promising approach to integrate wireless sensor and actuator networks (SANETs) with pervasive infrastructure over Internet by encapsulating distributed physical sensor and actuators into regular objects. Typically, SGs for SANETs are assumed to know operational environment in advance at design time with limited awareness of operational SANET conditions and, in the meanwhile,...
Advances in hardware development enable the creation of tiny and inexpensive sensor network devices which are widely disseminated in our daily life, and take a significant role in developing ubiquitous sensor networks (USNs). As the architecture of the sensor networks becomes to rely on the applications more heavily, we believe that it is considerably important to come up with USN middleware which...
In this paper we introduce a new framework for the development of context-aware knowledge by integrating the user's digital and physical environment. The developed knowledge can contribute to solve problems and challenges of wireless sensor networks within a context that is described by additional cyber-content. Sensor networks are exposed, intentionally or not, to dynamically changing network structures...
In order to suppress effectively the effects of RSSI error to wireless sensor networks node localization's precision in pervasive computing environment, individual diversity difference coefficient, distance difference coefficient and distance difference localization equation is defined based on the analysis of the models of maximum likelihood estimation and RSSI. The closest beaconing node to object...
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...
Wireless sensor networks (WSNs) provide various environment data in the real-world, and also WSNss middleware is able to offer field data in real-time by user queries. For materialization of the future ubiquitous computing which enables networking with things at anytime, anywhere and any-devices, WSNs occupy the important position with RFID technologies, and it has evolved and advanced currently....
