“…Many approaches to awareness, such as iQL [3] and ConStruct [15], derive directly from The Context Toolkit: a highly influential framework supporting context awareness in small scale environments [4]. In these frameworks, applications use a well known discovery service to select and combine resources (e.g., sensors or aggregators) in a pipeand-filter style according to semantic descriptions of their required inputs and outputs.…”

The emerging proliferation of devices with sensing and networking technologies offers opportunities for delivering pervasive services through interactions between spatially local resources. Here, applications are challenged to become aware of their surroundings: to discover, filter and reason on information relevant to their goals. Without centralised services to control information flow, decentralised mechanisms must partition these responsibilities across the environment. This paper explores a bio-chemically inspired approach to realising awareness in an open, dynamic setting, building towards complex self-organising awareness algorithms for data collection, reasoning, and querying. Through simulation we provide a preliminary evaluation of the proposed approach.

This requires accurate inference of user intent. Though individual user acts may be inferable from environmental context sensing, the inference of intent for which appropriate support might be offered is more challenging. Numerous researchers have used probabilistic techniques such as Bayesian Analysis techniques to attempt such inference. Unlike a desktop environment, however, pervasive computing environments are extremely heterogeneous, so any heuristics used must be tailored to the physical environment and the users in question. Thus these techniques are only likely to be accurate if configured with accurate knowledge of routine user behavior. Many existing approaches attempt to learn such knowledge from operational data, but this often requires user involvement in training and expert configuration of probabilistic processing structure. In this paper we examine a complimentary approach where users are presented with an intuitive interface to support the direct configuration of probabilistic structure by users with appropriate knowledge. By treating an intent inference system for a particular pervasive computng environment as an autonomic system, we approach the problem as the design of an intuitive governance interface for this system. We then present the design and usability evaluation of this governance interface.

Towards a Managed Extensible Control Plane for Knowledge-Based Networking

This paper proposes an open, extensible control plane for a global event service, based on semantically rich messages. This is based on the novel application of control plane separation and semantic-based matching to Content-Based Networks. Here we evaluate the performance issues involved in attempting to perform ontology-based reasoning for content-based routing. This provides us with the motivation to explore peer-clustering techniques to achieve efficient aggregation of semantic queries. The clustering of super-peers using decentralized policy engineering will deliver the incremental deployment of new peer-clustering strategies.
