Wireless sensor networks are designed for a very wide, yet specific, purpose. Their components have processing and power limitations. Due to these limitations, decisions by running complex algorithms with the information collected by sensors must be done in components external to the WSN. This document presents a combination of WSN and peer-to-peer networks to ease the development of systems that rely on WSN functionality. As a result, we propose the creation of a programing abstraction that allows developers to concentrate on the functionality of the developing system. We also propose the use of feedback loops as a way to design and develop the components of the abstraction and to define self-managing behavior for them. Those components should be also lowly coupled, interchangeable and extensible.
