Evolution of embedded systems tends towards still more dissemination and interaction between computing devices. This leads to new paradigms such as Internet of Things or Societal IT Systems for which new kind of services will be afforded by a coordinated interaction among devices. Such networked embedded devices imply emergent properties, so it is necessary to evaluate system performance such as latency, energy, and reliability. Efficient models, methods, and tools are expected to assist system architects in the process of dimensioning hardware and software resources of such systems. During this talk, I will present works led at University of Nantes in this domain, notably about the definition of a modelling method which aims at improving efficiency of performance models in terms of simulation speed and accuracy. This method uses both dynamic properties of architecture models and characteristics of discrete event simulators. It allows automatic abstraction of architecture models to better manage design complexity.


Dr Sebastien Le Nours is an associate professor at Polytech Nantes, the engineering school of University of Nantes, France. He is involved in teaching embedded system design and his research is led towards the improvement of the system architecting process of complex embedded systems. He is a member of IETR, a French research institute in electronics and telecommunications. He holds an engineering degree in electronic from ISEN, French ‘Grande Ecole d’ingénieur’. His PhD is in electronic (INSA Rennes, 2003) in which he works on optimization of signal processing algorithms and its implementation of heterogeneous architectures. During 2013, he is a visiting scholar at ITEE, University of Queensland.
