contextaware applications are seeking for the technologies that provides regularly available data between internal and external environments. Wireless access infrastructure is integrating real time data and heterogeneous devices to establish ubiquitous communication. A wireless sensor network (WSN) is primarily undertaking remote monitoring of any task in any sensing field further to extend for context fetching and refining to collect essential context information for pervasive environment. The applications are well utilized on context observation and interpretation for mobile users. The proposed method assists to combine various basic low level contexts to provide reliable decision making in the pervasive environment using sensor networks and context aware computing. Pervasive computing has powerful and influencing factors to establish dynamic and smart environment with its dominant features in the backend. Pervasiveness provides the regulated smart interactions and interfaces together to avail the information for various applications. Using rich context for event notification than simple position and time, aim to bring automated decision along with accuracy information. The proposed model also facilitate users and group members to create and submit an event. It provides ability to submit an event using a various mode of input.

We present a conceptual framework for location-aware community systems and results from two studies of how socially-defined places influence people's information sharing and communication *** first study identified a relationship between people's familiarity with a place and their desire for either stable or dynamic place-related information. The second study explored the utility of various system features highlighted by our conceptual framework. It clarified the role of place information in informal social interaction; it also showed that people valued, and were willing to provide information such as ratings, comments, and event records relevant to a *** preliminary findings have important implications for the design of location-aware community systems. In particular, they suggest that such systems must integrate information about places with data about users' personal routines and social relationships.

context aware computing as well as wearable and ubiquitous computing often attain with pattern recognition on incoming sensor data. Recognizing more (useful) contexts requires more information about the context, and thus more sensors and better recognition algorithms. In order to enable logic inference on incoming data, the proposed work assumes that incoming data are represented by means of semantic languages (e.g., RDF, OWL, etc.). Nevertheless, in a context aware computing purely logic-based reasoning on context may not be enough. So, the work introduces soft computing techniques to approximate context recognition. Specifically, this paper introduces an approach to context analysis and recognition that relies on f-SPARQL[1] tool, that is a flexible extension of SPARQL. In particular, in this work a JAVA implementation of f-SPARQL and the integrated support for fuzzy clustering and classification are discussed. This tool is exploited in the architecture that foresees some task oriented agents in order to achieve context analysis and recognition in order to identify critical situations. Finally, a simple application scenario and preliminary experimental results have been described.

Location awareness is a crucial part of the context-awareness mechanism for ubicomputing. This paper explores how usefull is the location awareness history for an office based low-cost context-awareness environment. Capturing location awareness data into a relational database is simple and feasible in office environment. We use extended SQL to access the location awareness history database to provide direct support for speech commands. The mechanism improve flexibility for developing contextawareness application in the Intelligent Environment.
