....to the user s personal preferences for information content, and environment context includes the user s location and current time of day. Context has been used in distributed event based applications for wide area networks. These applications are characterized by a publish subscribe model [4] [6], 11] where receivers subscribe to information of interest to them without regard to any specific source, while senders publish information without addressing it to any specific destination. Context awareness is very critical for mobile users. These users have at their disposal devices that are ....

....into higher level context information before use by applications. It is unreasonable to expect every application to work with the raw sensor data, and it is unscalable to expect a single context server to support the diversity of transformations and the scale of numerous applications and users [2]. We gratefully acknowledge the support of the Cisco Systems University Research Program, IBM, Microsoft Research, DoD MURI contract F49620 97 1 03821, and the Dartmouth Center for Mobile Computing. We therefore need an infrastructure to aggregate and transform low level sensor data for ....

....responsible for the execution of operators, the deployment of operator graphs, the dissemination of events, and the implementation of the name service. Resources and applications obtain Solar s services by connecting to any Planet. Further details about Solar are available in our earlier papers [5, 6]; in this paper, we focus on the naming system. A resource, such as a context source, may contact any Planet with a request to advertise a name, providing a graph specification if the name is context sensitive (see the advertise interface in Figure 2) The Planet creates an internal object as a ....

....process of every application into a series of modular and re usable operators, each of which is an object that subscribes to and processes one or more input event streams and publishes another event stream. We explore the background and justification for this design in an earlier paper [5]. We identify four common categories of operators. A filter outputs a subset of its input events. For example, a sensor publishes the temperature every 10 seconds while one application needs alerts only when the reading exceeds 90 degrees. A transJbrmer inputs events of type T1 and outputs events ....

Solar: An Open Platform for Context-Aware Mobile Applications - Chen, Kotz (2002) (2 citations) Self-citation (Chen Kotz) (Correct)
....[14] Solar is currently a work in progress. We have implemented a prototype based on Java, with early results and some applications described in a recent report [3] Solar is now evolving, based on our discussion of the challenges and design guidelines for a context aggregation infrastructure [2]. In this paper, we give an overview of Solar (Section 2) its operator graph abstraction (Section 3) and the overall system architecture (Section 4) 2 Solar model Context aware applications respond to context changes by adapting to the new context. These applications are active in nature ....
....operator trees form a directed acyclic graph, which we call the operator graph. Currently, Solar incrementally builds the operator graph as new subscription trees are added, sharing event streams wherever names match. We explore the background and justification for this design in an earlier paper [2]. Stateful operators may cause some complexity if shared across many applications. Consider a location aggregator that maintains the current location of all objects that are being tracked, and it publishes an event whenever an object changes its location. An active map now subscribes to this ....
