Automatic Consistency Assessment for Query Results in Dynamic Environments TR-UTEDGE-2007-005

Queries are convenient abstractions for the discovery of information and services, as they offer content-based information access. In distributed settings, query semantics are well-defined, e.g., queries are often designed to satisfy the ACID transactional properties. When query processing is introduced in a dynamic network setting, achieving transactional semantics becomes complex due to the o...

PAQ: Persistent Adaptive Query Middleware for Dynamic Environments

Pervasive computing applications often entail continuous monitoring tasks, issuing persistent queries that return continuously updated views of the operational environment. We present PAQ, a middleware that supports applications’ needs by approximating a persistent query as a sequence of one-time queries. PAQ introduces an integration strategy abstraction that allows composition of one-time que...

Passive Network-Awareness for Dynamic Resource-Constrained Networks TR-UTEDGE-2009-009

As computing devices and their users become increasingly mobile, the demand for information about the environment, or context, becomes of significant importance. Applications must be able to adapt themselves to the changing environment to satisfy users’ demands and to ensure that the application’s resource usage matches the environment’s capabilities. However, using traditional means, acquiring...

Adaptive Data Quality for Persistent Queries in Sensor Networks TR-UTEDGE-2008-001

Wireless sensor networks are emerging as a convenient mechanism to constantly monitor the physical world. The volume of information in such networks can be extremely large and, to be meaningful to applications, this information must be processed at the right level of accuracy. However, there is an inherent trade-off between achieving a high degree of data accuracy and the communication overhead...

SICC: Source Initiated Context Construction in Mobile Ad Hoc Networks TR-UTEDGE-2005-003

Context-aware computing is characterized by software’s ability to continuously adapt its behavior to an environment over which it has little control. This style of interaction is imperative in ad hoc mobile networks that consist of numerous mobile hosts coordinating opportunistically via transient wireless connections. In this paper, we provide a formal abstract characterization of an applicati...
