OverviewA. WSN Test-beds and the HOBNET ProjectB. IoT Test-beds: Main Challenges

- standardization- interoperability- security/trust

C. Potential Methodological Approaches- architectural designs - cloudification- virtualization- crowdsourcing

D. Potential themes for EU-Japan Cooperation

a) an all IPv6/6LoWPAN infrastructure of buildings and how IPv6 can integrate heterogeneous technology (sensors, actuators, mobile devices etc)

b) 6lowApp standardization towards a new embedded application protocol for building automation c) novel algorithmic models and scalable solutions for energy efficiency and radiation-awareness, data dissemination, localization and mobility d) rapid development and integration of building management applications, and their deployment and monitoring on FIRE test beds

A. HOBNET Main Objectives

- 4 academic groups (U. of Patras/CTI, U. of Geneva, U. Edinburgh, U. College Dublin)- 2 industries (Ericsson, Sensinode)- 1 end-user (Mandat International)

- Methodological Approach: We take a holistic approach addressing critical aspects at different layers (networks, algorithms, applications/tools) in an integrated way.

HOBNET Partners/Approach

Implemented smart/green scenarios• Local adaptation to presence• Emergency management• Electric device monitoring• CO2 monitoring• Maintenance control• Customization• Building 3D visualization & monitoring• Mobile phone ID• User awareness• Oil tank monitoring• Garden watering• Resources tracking and monitoring

The MI HOBNET test-bed

The UNIGE HOBNET test-bed

The CTI HOBNET test-bed

Main concrete results/Exploitation• 35% reduction of energy consumption• Ability to select the energy saving/comfort trade-off

• Exploitation:- rich standardization activities (IETF, ETSI M2M and One

M2M)- deployments in highschools- major strawberry plantation (smart watering)- major brewery factory (Heineken group) - a spin-off created (OptSense)

B. Challenges for IoT TestbedsA. Standardization•Revisiting fundamental issues in Low Power & Lossy Networks e.g. IPv4 -> 6LoWPAN/IPv6, HTTP-> CoAP, etc

B. Interoperability•IoT requires that they seamlessly and directly communicate with each other and the Internet (e.g. M2M communication)

C. Trust (not just Security) •Especially towards active end users involvement•Value of personal data, anonymity, privacy, identity management, open data, reputation mechanisms

Challenges for IoT Testbeds (II)

D. Mobile test-beds, easy of deployment, “plug and play” nature•To exploit FIRE test-beds outside academic environments

E. Multidisciplinarity•Economists (market analysis, business models, incentives mechanisms, )•Sociologists (analyze driver and barriers to technology adoption, models for societal value creation)

C. Potential Methods - Architectures• RESTful Architectural Style – Compatibility, seamless

interconnection with the Internet• Embedded systems (e.g. WSN) are abstracted as web-

resources (Constrained Application Protocol, easy to proxy from/to HTTP, every resource is identified by a URI) + 6LoWPAN (IPv6 over Low-Power Wireless Area Networks)

• Embedded functionalities are represented as web services

A HOBNET Example• BMS for smart/green buildings• Sensors and actuators represented as resources in

Resource Directory• External (non-technical) users may compose their

custom use-case scenarios by combining resources in logical expressions

Methods -Virtualization• Virtual layers enable bi-directional interactions from IoT

nodes to applications and vice-versa• Virtual layers are used to expose functional aspects and

information on IoT nodes as services• They allow to organize diverse sub-networks in a

homogeneous wayA Suggested Approach

• Organize several IoT networks under a virtual network• End users are offered a unique interface of interaction• A meta-layer provides access via an open interface,

regardless of how these resources are provisioned (e.g. fixed or mobile test-beds, physical or virtual resources)

Methods - Cloudification• Enables large scale integration - scalability• Provides network functionalities “as a Service” (e.g.

Testbed as a Service)• Merges IoT with other emerging paradigms of the Future

Internet (e.g. Semantic Web, Cloud Computing, etc)A Suggested Approach

• A taxonomy of test-beds. For each class, we define cloudification prerequisites

• Goal: individual test-beds to be organized in a meta-testbed platform

• A single application layer accessing and managing resources from all test-beds (access rights, reputation and trust mechanisms)

D. Potential themes for EU-Japan Collaboration

Themes:•Sensor Networks•IoT•Distributed Robotics•Social Networking

Application context:•Green/smart buildings•Smart Cities•Smart e-Health•Smart Grid
