A Study for a Name-based Coordination of Autonomic IoT Functions - Scientific paper

09.2018, G. Asaamoning, P. Mendes, A Study for a Name-based Coordination of Autonomic IoT Functions. inProc. IEEE WiMob/MobiEdge 2018, Sep. 2018.

The Internet-of-Things represent a future trend of the Internet, in which massive numbers of net- worked objects are assumed to have the capability of sharing data collected through sensing activities. It is envisioned that such objects are not dedicated hardware modules embedded specific machines communicating via proprietary wired or wireless networks to dedicated soft- ware applications. On contrary, Internet-of-Things may have a more autonomic deployment, in which objects are autonomous and communicate via existing IP based networks. Due to its distributed nature, there is the need to rely on autonomic networking to improve the efficiency while reducing the operational costs of Internet-of-Things frameworks. This paper aims to provide a study about the best data plane to support Internet-of-Things, and an analysis about the best model to support its distributed autonomic behavior.

Information-centric routing for opportunistic wireless networks - Scientific Paper

09.2018, P. Mendes, R. Sofia, V. Tsaoussidis, S. Diamantopoulos, J. Soares,Information-centric routing for opportunistic wireless networks. InProc. ACM ICN 2018, Sep. 2018.

 This poster describes DABBER, a protocol developed to extend the reach of Named Data Networking into wireless environments. Our key contribution lies in the fact that DABBER supports communication in op-portunistic wireless environments by relying on routing metrics that take into consideration node availability and centrality measures; data reachability metrics. The poster provides an overview to the DABBER architecture , and to the available open-source implementation.

The Role of Smart Data in Inference of Human Behavior and Interaction - book Chapter

04.2018: This chapter explores features, concepts, and provides guidelines concerning the role and applicability of smart data captured in a non-intrusive way, in the inference and contextualization of human behavior and interaction.

The chapter starts by introducing aspects related to human interaction, for instance, how to define and to best model physical and psychological proximity; models for social awareness and social contextualization. The next part of the chapter deals with interaction inference and interaction contextualization, namely: classification models that best suit the inference of behavior in the vere of smart data; challenges in regards to small data capture and behavior inference derived from small data, in particular when considering decentralized, mobile cyber-physical systems; guidelines to model interaction based on pervasive wireless sensing systems, including available middleware and systems (tools). The chapter then provides information concerning specific applicability use-cases, namely, Points of Interest detection via smart data, and how smart data can be used to boost social interaction in a pervasive, non-intrusive way. The chapter concludes with a set of recommendations.

DABBER: Data reAchaBility BasEd Routing for Named-data Networking Wireless Environments

03.2018: 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 has been submitted to IRTF, and was presented in the ICNRG meeting in London (Mar 17th - Mar 23rd 2018).

ACM ICN 2017 Tutorial on UMOBILE


COPELABS 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.

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

07.2017: 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).
