Submission of new Internet Draft to ICNRG

The European UMOBILE project is working on methods to extend NDN towards opportunistic wireless networks. In this context, COPELABS has been implementing an NFD extension, called NDN-OPP, which supports NDN multi-hop wireless communication: NDN-OPP V1.0 for Android does broadcast of Interest packets over a Wi-Fi direct network.

In order to reduce resource consumption in a NDN multi-hop wireless networks, COPELABS, SENCEPTION and ATHENA have created the DABBER routing protocol, which allows selective forwarding of Interest packets based on the local announcement of name prefixes + node awareness about the properties of neighbour nodes (centrality and availability). DABBER aims to operate on a point-to-point wireless network (e.g. Wi-Fi direct, DTN) as well as on a broadcast network (e.g. ah-hoc Wi-Fi).

DABBER was submitted to IETF, and will be presented in the ICNRG meeting in London (Mar 17th - Mar 23rd).

Participation in the ACM Information-Centric Networking 2017

posted Oct 10, 2017, 8:03 AM by Paulo Mendes   [ updated Oct 10, 2017, 8:05 AM ]

COPELABS and Senception participated in the ACM ICN 2017 Conference, which took place in Berlin from Sept 26th to Sept 28th.

On the first day, COPELABS and Senception provided a tutorial about the H2020 UMOBILE project, together with University of Cambridge (UK), AFA (Italy) and Athena (Greece). COPELABS provided a talk about NDN operation in Opportunistic Wireless Networks and Senception a talk about Social-aware metrics derived from contextualization. Senception also provided a demo of the PerSense Mobile Light tool.

On the second day, COPELABS participated in the poster and session section with a poster about Now@ - A Content Sharing Application over NDN, and a demo of NDN-OPP - Named-Data Networking in Opportunistic Networks.

Now@ and NDN-Opp are being developed in the context of the H2020 UMOBILE project.

NDN operation in Opportunistic Wireless Networks @ NDNcomm 2017

posted Mar 23, 2017, 7:53 AM by Paulo Mendes   [ updated Mar 23, 2017, 7:54 AM ]

[CAIDA - Center for Applied Internet Data Analysis logo]COPELABS presented NDN framework for Opportunistic Networks (NDN-Opp) at the NDN Community Meeting (NDNcomm 2017) in Memphis. 

NDN-Opp is being developed to extend the NDN framework in order to allow Named Data Networking in the context of opportunistic wireless networks. NDN-Opp is being developed based on NDN implementation for Android aiming to support opportunistic data forwarding based on users’ interests and their dynamic social behavior. Data is exchanged directly between mobile devices via Wi-Fi direct.

NDN-Opp is being developed in the context of the http://www.umobile-project.eu/.

COPELABS was present in the 2016 edition of the IEEE INFOCOM conference. We provided two demonstrations of technology related to Opportunistic Networking and Opportunistic Sensing.

Presence at ACM MOBICOM 2016

COPELABS and Senception delivered two demonstrations at ACM MOBICOM 2016.

Recommendations over Wi-Fi.

DDicas is a tool that relies on Wi-Fi fencing to perform user recommendations concerning local events or activities. DDicas has the following advantages: low-cost; no need to have constant Internet access; no need to have constant GPS access (works indoors and outdoors); advertisement provided based on interests, and not based on geo-fencing. DDicas is being developed by COPELABS in collaboration with Senception.

Small Group Safety Prevention.

PerSense Mobile Light is a tool developed by Senception to assist in research related with wireless roaming aspects. PerSense Mobile Light seamlessly captures wireless data (Wi-Fi and Wi-Fi Direct) thus providing traces that the wireless research community can rely upon to better characterize wireless roaming habits, as well as daily social routines. Developed in the context of the H2020 UMOBILE project, PerSense Mobile Light is currently available as a beta tool - to have access to it, please register via the Google+ Pervasive Sensing Experimental Tools community.

Pervasive people-centric sensing to infer about individual and collective behaviour

posted Jul 1, 2016, 7:45 AM by Paulo Mendes   [ updated Jan 26, 2017, 6:05 AM ]

Pervasive computing has been mostly used to build systems encompassing a small number of devices that interact with single users or small groups. As technology becomes truly pervasive, low-cost sensing systems may be built and easily deployed based on diverse sensing devices, such as mobile phones, which are carried by a large number of people, as well as embedded systems that can be integrated into self-propelled sensing

The CitySense project aims to develop a pervasive sensing system able to infer about individual behaviour (e.g. avoid social isolation, children protection), as well as collective behaviour (e.g. crowd control, detection of human swarms, urban sensing).

This project is a joint effort developed by COPELABS and Senception Lda.

In the context of promoting well-being several eHealth applications have been focused on tracking activities, such as sleep or specific fitness habits, with the purpose of promoting physical well-being with increasing success. Sensing technology can, however, be applied to improve social well-being, in addition to physical well-being. NSense has been developed within the CitySense project to capture and to infer social interaction patterns aiming to assist in the promotion of social well-being. Experiments carried out under realistic settings validate the NSense performance in terms of its capability to infer social interaction context based on our proposed computational utility functions. Traces obtained during the experiments are available via the CRAWDAD international trace repository.

Universal, mobile-centric and opportunistic communications architecture

posted Jul 8, 2015, 3:45 AM by Paulo Mendes   [ updated Jan 26, 2017, 6:12 AM ]

Cars, sensors, home appliances, every device in the daily life of citizens is becoming a constituent in Future Internet, adding to the need to reconsider requirements and assumptions in terms of network availability and affordability to support the ever increasing traffic demand. Still, the current Internet can only evolve adequately, if its infrastructure can be devised to accommodate the emerging services, which is very expensive.

The goal of the Horizon2020 UMOBILE project is to make the Future Internet universally pervasive, by supporting a diverse set of services. To achieve this, we are developing a universal mobile-centric and opportunistic communications architecture, which integrates the principles of Delay Tolerant Networking (DTN) and Information Centric Networking (ICN) in a common framework.

"The Universal, Mobile-centric and Opportunistic Communications Architecture project (UMOBILE) has received funding from the European Union’s (EU) Horizon 2020 research and innovation programme under grant agreement No 645124"

Dynamics of Social-aware Pervasive Networks

posted Apr 23, 2015, 2:41 PM by Paulo Mendes   [ updated Jan 26, 2017, 6:15 AM ]

Social-aware pervasive networks consider the users’ social behaviour to overcome intermittent end-to-end connectivity, inherent to this type of networking: forwarding decisions consider local knowledge about the behaviour of nodes to predict future encounters. 
Complex Network Analysis has been used to support contact prediction, by aggregating connectivity graphs into less volatile social graphs. Nevertheless, the structure of such graphs is rather dynamic, since users’ social behaviour and interactions vary throughout their daily routines and according to their mobility. Consequently, aggregation algorithms should be able to create social graphs that reflect the resulting dynamic behaviour of people. 

Hence, we have been investigating human behaviour aware aggregation algorithms aiming to create graphs based on social variations observed in people’s daily routines. By focusing on the dynamics of the network, we show that social graphs, reflecting different stages of human social behaviour and mobility, are able to take advantage of the potential small-world properties of networks in different time frames, improving the performance of social-aware opportunistic forwarding.
