ACM Transactions on Internet Technology, Special Issue on "Evolution of IoT Networking Architectures"

02.2019: ACM TOIT Special Issue on the Evolution of IoT Network Architectures.

To support the sheer number of entities connecting to the /Internet of Things (IoT)/, emerging IoT networks must support the stewardship of
large amounts of data, in-network and in-flight computation/AI, distributed storage, and rich queries. While today's IoT uses standard IP-based messaging, its shortcomings have led to proposed extensions for constrained environment operation, publish-subscribe middleware,
data-centric routing, among other technologies. This special issue aims to present the most leading-edge research on:
- Next-generation IoT network architecture & protocols*, including improved support for QoS/QoE, increased mobility, streaming media, and integrated security; a path from client/server centralized models to a fully distributed comms architecture; edge data producer disruption.
- Cross-layer design*, enabling real-time & near-real-time data delivery and synchronization; support for efficient multi-party communication; collective behaviors (e.g., crowd sensing, crowdsourcing, resource federation); impacting low-power design; the wireless & mobile edge.
- Novel approaches to Edge networking for IoT*, such as distribution & orchestration of network functions to best support data processing
and aggregation; seamless interoperation of static and mobile edge infrastructure & devices; resilience and dynamic adaptation; data caching and migration; autonomous operation vs opportunistic connectivity; the proliferation and peering of "edges".
IoT communication interoperability*, such as proposals to articulate in a distributed and self-organizing way communication between different communication protocols; support for a large variety of heterogeneous and constrained devices; discovery & directory services.
- Network measurement & performance*, to assist in understanding, exposing and comparing the performance of current IoT resources, infrastructure and protocols in a variety of scenarios, including industrial & consumer IoT.
- IoT Privacy, security and trust challenges*, including data security, user privacy, distributed trust models, attestation, privacy- and policy-preservation, encrypted search, access control and policy management.

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.

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).

BEING: Inference of Human Behavior via Network Mining

The BEING project (2018-2020) is focused on contextualization derived from data captured via wireless networks, and which today any device overhears. BEING expects to contribute to the development of pervasive wireless solutions, as well as studies in mining in wireless networks, to assist in a better and non-intrusive inference of human behavior, from an individual and collective perspective.


The IoT Lab is an experimental project of COPELABS dedicated to the exploration and analysis of networking architectures and communication protocols for multiple IoT environments, e.g., personal IoT and industrial IoT.  A few aspects being worked upon concern protocolar transmission and unified abstraction models for edge computing, as well as the relevancy of novel communication models (e.g., ICN) for IoT.
