Location awareness is the key capability of mobile computing applications. Despite high demand, indoor location technologies have not become truly ubiquitous mainly due to their requirements of costly infrastructure and dedicated hardware components. Received signal strength (RSS) based location systems are poised to realize economical ubiquity as well as(More)
Citrus is one of important fruits in Indonesia and its production increasing from 449.5 thousand tons in 1999 to 2.5 million tons in 2006, although slightly decreasing to 2.2 million tons in 2009. So far, citrus has been graded manually by the traders and processors into 5 classifications A, B, C, D, and E not conformed to SNI (Indonesian National Standard)(More)
Location awareness is key capability of context-aware ubiquitous environments. Received signal strength (RSS) based localization is increasingly popular choice especially for indoor scenarios after pervasive adoption of IEEE 802.11 wireless LAN. Fundamental requirement of such localization systems is to estimate location from RSS at a particular location.(More)
Location awareness is key capability of context-aware Ubiquitous environments. Received signal strength (RSS) based localization is increasingly popular choice especially for in-building scenarios after pervasive adoption of IEEE 802.11 wireless LAN. Fundamental requirement of such localization systems is to estimate location from RSS at a particular(More)
Location based services are becoming essential feature of context-awareness in ubiquitous computing. Reflective distribute component programming model is proposed to systematically provide location to location based services (LBS). We integrate distributed component technology and reflection to develop localization capability as middleware service. Concept(More)
The technology of multimedia content adaptation based upon the location of a target device can become the long expected killer application of ubiquitous computing. Easy to develop, lightweight, and robust location estimation is the core component of this technology. Until now, location estimation technology remains restricted to highly sophisticated(More)
Today mobile computing is pervasively taking over the traditional desktop computing. Mobile devices are characterized by abrupt and un-announced changes in execution context. The applications running on these devices need to be autonomous and thus dynamically adapt according to the changing context. Existing middleware support for the typical distributed(More)
Location systems are core technologies for enabling pervasive computing smart spaces. Signal strength based location estimation offers economical viability and sufficient accuracy for numerous location based services. Despite extensive research being carried out in this positioning method, tedious and lengthy development life cycle prohibits wide scale(More)
