In a Wi-Fi based indoor localization system (WILS), mobile clients use received Wi-Fi signal strength to determine their locations. A major problem is the variation of signal distributions caused by multiple factors, which makes the old localization model inaccurate. Therefore, the transfer learning problem in a WILS aims to transfer the knowledge from an(More)
With the development of pervasive computing, location information remains a crucial component of context-aware. The ability to provide multimedia service according to users' locations would be attractive for intelligent tourism, shopping guide, etc. In this paper, we present a prototype system for location-based multimedia service as a guideline to design(More)
Understanding human intention and performing different activities automatically is one of the key problems in pervasive computing. In this paper, a new location-based search computing framework (LoSeCo) is proposed to allow one's pervasive device to augment search devices. The objective of our problem is to recognize the real-time user goal through goal(More)
In order to realize security checking on power communication operation mode, we introduce a new method for service and system security checking and analyzing, which include the multidimensional analysis and the N-1 service impact analysis. Based on this method we managed to design and realize the system, which can monitor and display the effective mode(More)
