....paper we address this fundamental challenge by proposing a graph abstraction for context information collection, aggregation, and dissemination, and show how it should be able to meet the flexibility and scalability challenges. Its security and privacy features are addressed in a companion paper [18]. We propose our graph based abstraction in Section 2. In Section 3 we show an example graph shared by several context aware applications that are being developed using our Solar prototype, whose architecture and implementation are discussed in Section 4. We present some results of early ....

....and operator graph abstractions provide a basis for flexible, decentralized access control. Our approach is based on information flow principles, with relaxation mechanisms to allow flexible user control over access to context about themselves. We describe our security model in a companion paper [18]. 4 The Solar system We are building a prototype infrastructure for context collection, aggregation, and disseminafion, based on the operator graph abstraction. In this section we describe the system architecture of our prototype, the Solar system, and discuss some implemen tation details. ....
