ALPINE

A Low Power, Intelligent, sensor Network architecture for Environmental management

The goal of the ALPINE project was the design, implementation and evaluation of low power, energy-efficient sensor networks together with a suite of high-level, programming tools that are tailored to the specific requirements of real-time environmental management. Our work has a special focus on the investigation of the bidirectional relationship between large scale urban development and the natural habitat of man, fauna and flora. We evaluate our generic solution with the help of two pilot applications, one in the domain of hydrological infrastructure management and one in the area of bear and wolf management.

In this work we propose a sensor network architecture that is tailored to environmental management. It is application-driven and comes together with a software suite of high-level, reactive and scalable programming abstractions, developed at the University of Cambridge. Real-time monitoring applications can be programmed with the help of these tools instructing the sensor network to monitor continually in real time both the physical world and/or man-made infrastructure such as hydrological networks and proximity to public roads , in order to detect situations of interest of arbitrary complexity, e.g., that there is a sudden drop of pressure in a water pipe causing potential shortage in some part of the city or that a stressed bear trying to cross the highway at a location where there is inadequate fencing leading to possible fatalities. Such situations are specified by means of a high-level, domain specific language ALPINE, which is based on temporal first-order logic and has expressiveness close to human intuition. More specifically, ALPINE is capable of expressing negation, i.e., absence of data, making it possible to capture the fact that “a designated highway underpass is not actually used by bears and is therefore not meeting its functional requirements”.
