QARI: Quality Aware Software Deployment For Wireless Sensor Networks

If the people are to deploy sensor applications in a realistic business context, the authors must provide innovative middleware services to control and enforce required system behavior; in order to correctly interpret collected temperature data, for example, sensor applications require guarantees about minimal coverage and the number of available sensors. The extreme dynamism, scale and unreliability of wireless sensor networks represent major challenges in contemporary software management. This paper presents QARI, a middleware service for decentralized and quality aware software deployment, which offers a simple yet flexible way to define, enforce, and maintain software deployment specifications.
