The last five years have been witness to an unprecedented level of growth and development in the sensornet research field, with these sensor networks being used in a wide variety of applications. In order to allow for such rapid innovation, relatively few architectural restrictions were put in place, in terms of standard interfaces and defined layering schemes, resulting in monolithic, and largely non-reusable, implementations. The goal of this research is an overall sensornet architecture that will help tame the increasingly complex structure of wireless sensornet software and help foster greater interoperability between different code bases.

The Sensornet Protocol (SP), the first step towards this architecture, was a unifying link layer abstraction, serving as the narrow-waist of the architecture in a manner similar to IP. Subsequent work introduced a modular network layer framework that defined and componentized the responsibilities of the network layer. Current work focuses on a platform-independent link estimator, an energy monitoring and management system, as well as reliable transport protocols.
