This study proposes mobile services with time constraints in ubiquitous computing environments based on on-demand mode. For real-time mobile service, the need of mobile service for a real-time database management model is strong and providing real-time response to mobile transaction has became basic strategies in mobile data management. However, the resource constraints of ubiquitous computing systems...
This paper describes mobile services with time constraints in ubiquitous computing environments. In a ubiquitous computing environment, the need for a real-time database management model is strong, because one of the basic requirements in mobile data management is to provide real-time response to transactions of the underlying strategies. However, the resource constraints of ubiquitous computing systems...
