Design of a generic smart and wireless sensors network -Benefits of emerging technologies

Résumé

More than technological questions, the generic potentiality of a wireless sensors platform drives the way engineers could design the system. A complex equilibrium must be found between the desire to implement generic (at least reusable) functionalities embedded in each wireless sensor of the network and the necessity of electronic optimizations in view of reducing energy consumption and dimensions. Nevertheless, nearly each specific application that has to be implemented on a wireless sensors network can be approach through a generic way of thinking. As an example, a relevant solution consists in designing sensor that is the compilation of heterogeneous electronic boards plugged one onto the others; one is the mother board that ensures fundamental functions from signal processing to wireless communications and some are pluggable boards each dedicated to a specific sub-function (data acquisition, conversion from a sensing component, filtering,...). But the wireless constraint and the wish of generic designs ask the questions of time synchronization, energy consumption... thus emerging technologies and protocol standardization (Zigbee, Wi-Fi) could provide immediate answers. French Public Works Laboratory (LCPC) has recently developed a generic wireless platform that fits many applications needs such as U.A.V. instrumentation, bridge or quarries monitoring... By including the TCP/IP stack and an embedded ucLinux O.S. at each sensor level, LCPC could propose a generic and reusable platform on which many applications could be implemented. This article aims at presenting the originalities of that wireless sensors platform and the first positive results and dissemination it recorded when applied to real structures.
