About the research centre or Inria department

The Inria Rennes - Bretagne Atlantique Centre is one of Inria's eight centres and has more than thirty research teams. The Inria Center is a major and recognized player in the field of digital sciences. It is at the heart of a rich R&D and innovation ecosystem: highly innovative PMEs, large industrial groups, competitiveness clusters, research and higher education players, laboratories of excellence, technological research institute, etc.


The European Union  is willing to design a trusted, best-in-class European-owned software platform for development, deployment and management of applications across the cloud-to-edge continuum, from central infrastructure to devices. It is important to deal with energy efficiency to reduce (or save) electricity consumption and CO2 emissions to limit global warming. It is typically true due to a massive expected of edge sites submitted to  power and heat constraints.

The purpose of this thesis is to analyze strategies of cloud actors, their impact, and regulation procedures which could lead to socially-improved situation.
The objective is the optimisation of workload and resources placement for power efficiency.


  1. The PhD is part of the E2CO Platform project (European Edge Computing platform & ser- vices) which aims to develop a highly scalable, federated, trusted edge service platform, supported by an ecosystem of cross-industry users and technology providers.

    The PhD will take place will be realized within the Inria Dionysos team, specialized in network economics, one of its main research activities. Network economics can be (and should be) used to understand what happens with entities/operators wishing to optimize their revenue which can be in contradiction with carbon footprint limitation.

Main activities

The project consists of several actions:

  • Model edge nodes and infrastructure costs, interests and goals.

  • Use of tools from game theory to determine the best strategies of resource placement and use in the cloud for energy-aware actors.

  • Study of what happens if some actors are “energy-compliant" while others are not.

  • Then using more precisely mechanism design theory will be considered to determine rules (e.g., regulation) which could be imposed for resource placement and strategies implement- ing a trade-off between carbon emissions/power saving and quality of service/experience. Financial and technical regulation can be applied and will be studied toward this goal, and compared to determine the best strategy

The output will contribute to:

  • Allow for the analysis of the effectiveness of placement strategies before their deployment.

  • Investigate appropriate regulation procedures (if needed) towards energy-aware placement strategies.


Networking knowledge expected, as well as interest for modeling/performance evaluation.
