System Design of Internet-of-Things for Residential Smart Grid
Internet-of-Things (IoTs) envisions to integrate, coordinate, communicate,
and collaborate real-world objects in order to perform daily tasks in a more
intelligent and efficient manner. To comprehend this vision, this paper studies
the design of a large scale IoT system for smart grid application, which
constitutes a large number of home users and has the requirement of fast
response time. In particular, we focus on the messaging protocol of a universal
IoT home gateway, where our cloud enabled system consists of a backend server,
unified home gateway (UHG) at the end users, and user interface for mobile
devices. We discuss the features of such IoT system to support a large scale
deployment with a UHG and real-time residential smart grid applications. Based
on the requirements, we design an IoT system using the XMPP protocol, and
implemented in a testbed for energy management applications. To show the
effectiveness of the designed testbed, we present some results using the
proposed IoT architecture.Comment: 10 pages, 6 figures, journal pape
Digital Barriers: Making Technology Work for People
This paper was originally given as an oral presentation at the ā3rd International Conference for Universal Designā, International Association for Universal Design, Hamamatsu, Japan (2010) and subsequently published. Peer reviewed by the conferenceās International Scientific Committee, it looks at how the emerging techniques of design ethnography could be applied in a business context and qualitatively evaluates the benefits. It outlines the differences between inclusive design research conducted for digital devices/services and the large body of existing research on inclusive products, buildings and environments. It advances the view that technology companies are today in danger of repeating the same inclusive design mistakes made by kitchen and bathroom manufacturers 20 years ago, and calls for technology companies to develop new techniques to avoid this happening.
The paper charts in detail the challenges and processes involved in transferring academic inclusive design research into the business arena, describing research conducted by Gheerawo and his co-authors on projects with research partners Samsung and BlackBerry. The paper helped define the āpeople and technologyā research theme in the Helen Hamlyn Centre for Designās Age & Ability Research Lab, which Gheerawo leads. It was also important, as part of evidence of the benefits of an inclusive technology approach, in persuading a number of companies (Sony, BT, Samsung) to undertake new studies with the Lab.
Gheerawo used this pathfinder paper in further work, including an essay on digital communication for www.designingwithpeople.org (i-Design3 project EPSRC), membership of the steering committee for Age UKās Engage accreditation for business, and lectures at āCitiesforAllā conference, Helsinki (2012), āWorkTechā, London (2010), āBudapest Design Weekā (2011) and the āBusiness of Ageingā conference, Dublin (2011). Gheerawo also co-wrote an article āMoving towards an encompassing universal design approach in ICTā in The Journal of Usability Studies (2010), for which he was also a guest editor
First experiences with Personal Networks as an enabling platform for service providers
By developing demonstrators and performing small-scale user trials, we found various opportunities and pitfalls for deploying personal networks (PNs) on a commercial basis. The demonstrators were created using as many as possible legacy devices and proven technologies. They deal with applications in the health sector, home services, tourism, and the transportation sector. This paper describes the various architectures and our experiences with the end users and the technology. We conclude that context awareness, service discovery, and content management are very important in PNs and that a personal network provider role is necessary to realize these functions under the assumptions we made. The PNPay Travel demonstrator suggests that PN service platforms provide an opportunity to develop true trans-sector services
Internames: a name-to-name principle for the future Internet
We propose Internames, an architectural framework in which names are used to
identify all entities involved in communication: contents, users, devices,
logical as well as physical points involved in the communication, and services.
By not having a static binding between the name of a communication entity and
its current location, we allow entities to be mobile, enable them to be reached
by any of a number of basic communication primitives, enable communication to
span networks with different technologies and allow for disconnected operation.
Furthermore, with the ability to communicate between names, the communication
path can be dynamically bound to any of a number of end-points, and the
end-points themselves could change as needed. A key benefit of our architecture
is its ability to accommodate gradual migration from the current IP
infrastructure to a future that may be a ubiquitous Information Centric
Network. Basic building blocks of Internames are: i) a name-based Application
Programming Interface; ii) a separation of identifiers (names) and locators;
iii) a powerful Name Resolution Service (NRS) that dynamically maps names to
locators, as a function of time/location/context/service; iv) a built-in
capacity of evolution, allowing a transparent migration from current networks
and the ability to include as particular cases current specific architectures.
To achieve this vision, shared by many other researchers, we exploit and expand
on Information Centric Networking principles, extending ICN functionality
beyond content retrieval, easing send-to-name and push services, and allowing
to use names also to route data in the return path. A key role in this
architecture is played by the NRS, which allows for the co-existence of
multiple network "realms", including current IP and non-IP networks, glued
together by a name-to-name overarching communication primitive.Comment: 6 page
Scenarios for the Internet Migration of the Television Industry
All the conditions for the television industryās migration to the Internet are now in place. While this migration will be gradual, it will have a deep-seated impact on the industry:ā¢the exclusive rights model will no longer be the standard;ā¢some consumers will abandon traditional managed networks;ā¢a globalization trend will be sparked, to the benefit of the major rights holders. Unlike the music and print media industries, the TV industry is gaining a strong position on the Web. As a result, television is poised to play a central role in video services. This offensive strategy will likely pay off down the line, but does not entirely eliminate the possibility of destroying value. There are structural reasons for this, including a fiercely competitive online advertising market and a lack of control over program circulation. Far from being simply transitory, the 2009-2010 economic downturn marks the beginning of a decade of restructuring for the TV industry. This new period will begin with an overall decline in the sectorās resources before increasingly varied consumption patterns spur a new period of growth. The decade running from 2010 to 2020 will also be a period that focuses on cost control, with the industrialization of TV production that will depart once and for all from its historical model, i.e., film. This migration to the Web poses a threat to the European industry in particular. A reassessment of the television industryās regulatory strategy appears both necessary and urgent, and will involve the creation of integrated pan-European conglomerates.Television, video, networks, on-demand, connected devices, advertising, pay-TV.
Context-aware Dynamic Discovery and Configuration of 'Things' in Smart Environments
The Internet of Things (IoT) is a dynamic global information network
consisting of Internet-connected objects, such as RFIDs, sensors, actuators, as
well as other instruments and smart appliances that are becoming an integral
component of the future Internet. Currently, such Internet-connected objects or
`things' outnumber both people and computers connected to the Internet and
their population is expected to grow to 50 billion in the next 5 to 10 years.
To be able to develop IoT applications, such `things' must become dynamically
integrated into emerging information networks supported by architecturally
scalable and economically feasible Internet service delivery models, such as
cloud computing. Achieving such integration through discovery and configuration
of `things' is a challenging task. Towards this end, we propose a Context-Aware
Dynamic Discovery of {Things} (CADDOT) model. We have developed a tool
SmartLink, that is capable of discovering sensors deployed in a particular
location despite their heterogeneity. SmartLink helps to establish the direct
communication between sensor hardware and cloud-based IoT middleware platforms.
We address the challenge of heterogeneity using a plug in architecture. Our
prototype tool is developed on an Android platform. Further, we employ the
Global Sensor Network (GSN) as the IoT middleware for the proof of concept
validation. The significance of the proposed solution is validated using a
test-bed that comprises 52 Arduino-based Libelium sensors.Comment: Big Data and Internet of Things: A Roadmap for Smart Environments,

A Taxonomy of Self-configuring Service Discovery Systems
We analyze the fundamental concepts and issues in service
discovery. This analysis places service discovery in the context of distributed
systems by describing service discovery as a third generation
naming system. We also describe the essential architectures and the
functionalities in service discovery. We then proceed to show how service
discovery fits into a system, by characterizing operational aspects.
Subsequently, we describe how existing state of the art performs service
discovery, in relation to the operational aspects and functionalities, and
identify areas for improvement
