NDN contributions in the context of the H2020 UMOBILE project

Within the European project H2020 UMOBILE the research group SITI (Informatics Systems and Technologies) of the R&D lab COPELABS, University Lusófona,  is investigating the usage of NDN- Named Data Networking to extend data-centric communications into more dynamic wireless scenarios, such as emergency situations, or accessible communications.

With this propose, COPELABS is devising an NDN Android implementation for opportunistic networks, called NDN-OPP, and two applications: a content sharing application called Now@; a short messaging application, called Oi!.

Based on NDN-OPP, both Now@ and Oi! applications are able to exchange data and send short messages, respectively, directly between neighbor devices, via Wi-Fi direct, of via an access network, via Wi-Fi.

Still within the UMOBILE project, SITI/COPELABS is creating a local testbed, encompassing SAMSUNG smartphones, Wi-Fi access points and one NDN router, which provides access to the NDN Global test bed.



Paper Now@ - Content Sharing Application over NDN - ACM ICN 2017, Aponte, O. and Mendes, P.


Sharing content has become part of our lives; Twitter for instance, is one of the most popular application in this area with millions of users in the entire world. At the same time, in the recent years, Named-Data Networking has become a promising network infrastructure, with continuous growth and collaborating teams that are working on it. In this paper we describe Now@, aiming to increase the impact of NDN near the end user with an Android application that allows them to exchange data based on their interests. To achieve this goal, we have developed Now@ based on synchronization of data. Now@ can operate on top of NFD Android allowing data exchange via wireless Internet and on top of NDN-Opp allowing data to be exchanged even in the presence of intermittent connectivity.


 ACM ICN Tutorial on UMOBILE

SITI participated in the ACM ICN conference organizing a tutorial in the context of the H2020 UMOBILE project.

UMOBILE integrates the principles of Delay Tolerant Networking (DTN) and Information Centric Networking (ICN) in a common framework. By relying on an instance of the UMOBILE architecture, users are able to share information directly with other peers without relying on infrastructure or expensive connectivity services; providers are able to provide services in remote areas as well as in scenarios with intermittent internet access.


This tutorial intends to go over three main innovation aspects concerning ICN: i) NDN operation in opportunistic wireless networks based in contextual awareness; ii) the integration of DTN and NDN to facilitate communications when network is impaired; iii) the UMOBILE Lab: the first NDN/ICN testbed federated in Europe.



TUM Kolloquium: Contextual Interaction inference and characterization derived from wireless network mining


Video available via the TUM media portal

This talk is focused on wireless network mining and on context and behavior characterization derived from the application of non-intrusive, pervasive sensing approaches in connected wireless environments. The research described in this talk goes over the development of networking solutions and mechanisms that can assist data capture and distributed inference of roaming habits in a way that may lead to social interaction stimulation (and as a consequence, to a better design of networking communication).

NDN-Opp: an NDN Opportunistic Framework

COPELABS is specifying and investigating how to extend NDN to be applicable in the context of opportunistic wireless environments. The NDN framework for Opportunistic Networks (NDN-Opp) is being developed aiming to support opportunistic data forwarding based on users’ interests and their dynamic social behavior.




Oi!: Communicating directly, without Internet access

COPELABS is developing, in the context of the H2020 UMOBILE project, a set of applications that does not require Internet access for users to exchange information. Such opportunistic transmission applications rely on social interaction between devices to better propagate (route) information.

Oi! is one of such tools. Under development with the purpose of allowing message exchange without Internet access, Oi! considers the SOCIO framework to better select nodes to propagate the messages to.

NSense: A People-centric, non-intrusive Opportunistic Sensing Tool for Contextualizing Social Interaction

The scientific paper NSense (Rute C. Sofia, Saeik Firdose, Luis Amaral Lopes, Waldir Moreira and Paulo Mendes) has been accepted in IEEE Healthcom 2016 (September 14th-18th, Munich). NSense is a software tool developed by COPELABS that tracks and infers social interaction aspects in the form of computational utility functions that aim at describing two indicators of interaction: propinquity, and social interaction level.
