Associate team EMBRACE, to meet the challenges of 5G

  • Name : EMBRACE
  • Inria Team : TRiBE
  • Partners : 3 Brazilian universities (Federal University of Minas Gerais, Federal University of Goiás and Federal Technological University of Paraná)
  • Project : The main objective of EMBRACE is to address scientific challenges based on real-world data sets describing the behaviour of network users. Specifically, EMBRACE is based on modeling human behavior in terms of mobility, content demand, interest, and interactions.
  • Keywords : network, 5G, modeling, heterogeneity, resources, human behavior, mobility

Founded in 2017, the EMBRACE associate team is the result of a collaboration between the center’s TRiBE team (previously Infine) and 3 Brazilian universities : the Federal University of Minas Gerais (UFMG), the Federal University of Goiás (UFG) and the Federal Technological University of Paraná (UTFP). EMBRACE (lEveraging huMan Behavior for Resource AlloCation and services orchestration modEls) aims to better represent uncertainty and user profile in 5G networks by building user-friendly resource allocation models. Thus, the novelty lies in algorithms that will allow the exploitation of information extracted from their behavior, as well as from the uncertainty and heterogeneity of users.

The consortium has been carefully put together to bring together qualified partners to meet this challenge. Note that the teams involved have a long history of collaboration that began in 2011, including the joint publication of numerous research papers and the co-supervision of students.

Aline Carneiro Viana, head of the EMBRACE team, tells us more about the results and perspectives of this associate team.

What was the interest for you to propose an associate team?

It was important to determine an administrative, scientific and legal framework to better formalize our collaborations with our Brazilian partners. But above all, the creation of EMBRACE allowed us to obtain the necessary funding for both the visit of Brazilian students and researchers to France and the setting up of several training courses for students in France and Brazil.

What were the benefits?

The synergy between the different partners was already in place when EMBRACE was created: we were used to working together outside of this associate team framework. Moreover, the collaborations are still ongoing with the participation of 1 professor from UFMG and 2 professors from UFG in research, 3 of my PhD students (including two co-supervisors with IPP and UPSaclay) and students from UFG.

What were the results?

Our work has resulted in numerous publications and the organization of a workshop (CoUrb 2018) during the Brazilian SBRC2018 conference: this is a major event in Brazil in the field of “computer networks”. In terms of scientific results , we have developed methodologies to better understand the mobility behaviors of users in their routine and moments of exploration. We have also studied the impact brought by the routine mobility of users in the points of interest of a city and we have adapted the profile and interest of users to the allocation of resources in the network (where, when and how many resources to allocate).

5G networks enable both the emergence of new tourism services with difficult communication requirements (such as augmented reality applications) and visitor experiences involving physical and virtual space. Motivated by these challenges, we have gone a step further by focusing on a tourist-like population without a particular mobility routine.

We also propose a new multi-user travel itinerary planning framework based on an optimal problem formulation that takes into account both the individual travel itinerary (the tourist’s preferences, time or cost) and the constraints of the tourist service (the resources and applications of the cloud near the periphery). The main idea is to maximise the itinerary score of individual visitors, while optimising the allocation of resources in the periphery. On this subject, a first publication has been published on the occasion of the IEEE GLOBECOM 2019 conference and an extension for a journal is also being prepared.

In addition, the EMBRACE associate team gave us the opportunity to set up 2 Joint PhD:
– the first one between Inria-University Paris-Saclay and UTFPR ;
– the second, currently being signed, between Inria-Institut Polytechnique de Paris and UFMG.
