DirecciónThe Mobile and Wireless Internet (MWI) group at i2CAT is looking for an Engineer / Researcher to work on Energy optimization topics within the framework of the SNS BeGREEN project https : / / www.sns-begreen.com / .
BeGREEN project will take a holistic view to propose evolving radio networks that not only accommodate increasing traffic and services but also consider power consumption as a factor.
The Engineer / Researcher will carry out experimental research evaluating the power saving mechanisms available in compute platforms used to instantiate 5G network functions (e.
g. management of CPU states). The successful candidate will also work on the development of algorithms that can best exploit the available power saving mechanisms to minimize power consumption without affecting traffic performance.
The successful candidate will be part of the O-RAN team within MWI-SDWN directly contributing to BeGreen WP4, attending meetings and contributing to the project deliverables and publications.
The successful candidate will report to a senior researcher of the theam and collaborate with other junior and senior researchers at MWI that focus on 5G and Open RAN topics and are also contributing to the BeGreen project.
The candidates responsabilities include :
- Develop a testbed for evaluating energy consumption of 5G network functions on existent compute platform
- Carry out performance evaluation to understand impact of compute power saving mechanisms on energy consumption and traffic performance
- Propose and evaluate algorithms that exploit platform power saving mechanisms to reduce energy consumption
- Contribute to deliverables and publications
Besides contributing to the BeGreen project, the expected outcome of the work carried out is to develop a mechanism that adjusts CPU power states to reduce energy consumption in virtualized UPF systems.
The designed system should be portable to any x86 or ARM compute platforms.
