  Solutions for the self Adaptation of Communicating Systems in Operation

ANR Sacso

   Welcome to the ANR SACSO WebSite

In the context of high performance systems and critical applications, thegeneral objective of the project is to design Self-Adaptive Systemswhich are capable of monitoring the surrounding environment and adaptthemselves to different scenarios and requirements. In other words, aSelf-Adaptive System must be able to provide the required highperformances regardless the application mode and despite the changingenvironmental conditions.

The fundamental concept of self-adaptationby itself is not completely new: self-calibration techniques appliedafter manufacturing have been developed to deal with the many sourcesof technological variations and self-compensation techniques appliedduring the lifetime of the system have been developed to deal withthe ageing effects.

In this project, we address two non-classicalcases of self-adaptability: self-adaptation to the application andself-adaptation to the environment. Concerning self-adaptation to theapplication, on one hand, the performances of the complete systemwithin the application are limited by the performances of eachindividual component or sub-system. On the other hand, theperformances of the individual components or sub-systems areoptimized for a large range of future systems or potentialapplications and not for a specific one.

The originality of the approach proposed in this project is to ‘anticipate’ the systemdeployment while designing the components, i.e. the components aredesigned with an integrated ‘Self-Adaptation Circuitry’ whichenables them to autonomously modify their electrical characteristicswhen they are deployed into the application, in order to optimize theperformances of the complete system.

Concerning self-adaptation tothe environment, it is to note that the performances of the systemalso depend on the changing environment. As an example, a cell-phonesystem may communicate differently when it is operating in-door orout-door, when there are obstacles in the measurement environmentthat could disturb the reception, etc. Here again, the components,provided with a dedicated ‘Self-Adaptation Circuitry’ (SAC), maybe able to autonomously adapt their electrical characteristics to thechanging environment, in order to optimize the system performances.
