“…All these types of context must be considered when building a comprehensive management system. We assume that the context information has been gathered in a context memory (Ba"os et al, 2006;Salo et al, 2007) that feeds it to the PG. The PG generates different types of policies: user policies, application policies, service provider policies, network provider policies and service-specific policies.…”

“…We include this monitoring scheme as a part of the multi-level overlay scheme, previously proposed in [8], to handle redundant context information. It aids the CSON-D protocol [8] [9] and other similar context aware protocols for ANs [4], as the specifics of the context disseminated depend upon the availability of the monitored contexts. The main contributions of this paper include: 1) the context monitoring scheme, 2) the adaptive optimizations, and 3) and experimental results.…”

“…Context awareness plays a vital role in heterogeneous networks and systems, such as Ambient Networks (AN), and is a proven efficient approach for adapting network services [1] [2][3] [4]. Monitoring of context information to efficiently enable context-awareness in various applications is being under vigorous research.…”

Presently, smart interconnected heterogeneous devices with built-in GPS, Wi-Fi, and Bluetooth capabilities are more affordable, resulting in numerous novel mobile applications. To adapt applications based on the environment they are executed in, we perform context management by proactively monitoring the (network-and location-based) context information available in such devices and applications. As this requires continuous monitoring, the common fixed data flow based technique for forwarding contexts from multiple context sensors is not energy efficient. In this paper, we propose the design and implementation of an adaptive context monitoring scheme. Alongside context awareness, we employ overlay network, agent, and policy theories. We utilize learning and personalization characteristics to make an optimized judgment of context information in an efficient and scalable fashion. This paper is complemented with protocol evaluations to validate scalability claims based on real logs.

This paper summarizes and expands the ContextWare architecture proposed for context dissemination and aggregation for Ambient Networks European research project. ContextWare deals with sources of context, the way of acquiring context data from sensors, and its distribution to interested context consumers in an uniform form. Components of ContextWare architecture are described in details. Paper specifies Context Source, which is an abstraction of context provider, Context Manager, which handles high-level context aggregation and processing, Context Coordinator, which is used for handling large set of dynamic Context Sources, and Triggering, which assures context consistency. The collaboration of these components is illustrated with a scenario, which presents usage of ContextWare architecture within AN application. The system was successfully used in the Ambient Networks Project.
