Architectures for modular smart sensor systems

Many modular platforms have been developed to facilitate the design and implementation of smart sensing systems. Modular platforms can be of great benefit for system prototyping but the way they were initially designed can also limit the possibilities of building and testing new concepts. In a time where smart and ubiquitous sensor systems are of increasing interest, allowing to have the sensor´s data available always and anywhere, it is also of great importance knowing what are the main features a sensing platform should have to allow the development and fast prototyping of new innovative sensor based systems. This article focuses on the architectures commonly used by modular and portable sensor platforms, discussing some practical implementations. At the same time is presented a new architecture characterized by high flexibility avoiding smart sensor´s redesign each time a new communication paradigm arises.
