Abstract

In this paper we describe ConStruct, a distributed, context-aggregation based service infrastructure which supports the development of context-aware applications. ConStruct operates by automatically generating and maintaining directed context-processing graphs which connect applications to the sources of data they require at a relevant level of abstraction. The infrastructure also supports the dynamic creation of context processing elements to bridge gaps between available and requested information. ConStruct provides a reliable, scalable infrastructure; focused on self-maintenance in order to alleviate developer workload. We describe the infrastructure design and implementation, the associated programming model, and our planned extensions to the infrastructure.
