For years there has been an implicit assumption that the economic growth is dependent on emission growth. However, ICT has the potential to reduce energy consumption of almost all other industries. GeSi SMARTer2030 (2015) report1 shows that ICT has the potential to enable a 20% reduction of global CO2 emissions by 2030, thus holding emissions at 2015 levels, and demonstrating that judicious usage...
Spectrum management needs to be effective, in that spectrum must be allocated to the right uses, and efficient, in that spectrum must be assigned to those that value it the most. Technological advances and demands for further spectrum availability from mobile broadband operators (among others) require spectrum management to timely and firmly incorporate schemes to increase the technical efficiency...
This study demonstrates how a maturity model on Green ICT can help organisations improve themselves and become more environmental sustainable in a standard and efficient manner. For this we have used the SURF Green ICT Maturity Model and facilitated the use of this model in four organisations. These organisations participated in a maturity scan, evaluation session to discuss the results of the scan...
This work presents a new development model for wireless community networks, framed within the sustainable development goals, SDG 11, to achieve the transformation of cities to environmentally sustainable areas and to take measures to fight climate change; this model is based on the use of renewable energies, mesh routing protocols, the monitoring of air quality and environmental variables, IoT, and...
Recent explosion of SDN (software-defined networking) paradigm is steadily facilitating the open evolution of legacy protocol-biased networking. In this paper, we design and develop middle-box splitting functionalities for chunked video exchanges (i.e., file transfer and streaming) over multiple concurrent paths over South Korea, Malaysia, and Thailand parts of OF@TEIN SDN-Cloud playground. To reduce...
This paper deals with the challenges posed to human safety in the emerging IoT and ubiquitous network scenario by super intelligent machines/cognitive robotics that would coexist in the upcoming heterogeneous world comprising humans and super intelligent machines. Questions of trust in the super intelligent machines have been raised by scientists, sociologists, industry stalwarts, etc. After deliberating...
Unprecedentedly a massive number of devices are getting connected in the coming era of the Internet of Things (IoT). For discovery, remote access and management of these IoT devices, an IoT directory service is needed to store and provide their various attributes such as location, generated data types, owner's name, and security keys. In this paper, we present the architectural design of the IoT directory...
Space division multiplexing (SDM) is expected to be a key technology both for dealing with the future capacity crunch facing traditional single-mode fibre (SMF) and for realizing a sustainable optical network that can accommodate the various data streams originating from, for example, future 5G communication, the Internet of things (IoT), and machine to machine (M2M) networks. This paper describes...
Japan's low birthrate and rapidly aging population are causing medical expenses to take up ever more of the national budget and leading to a shortage of young medical professionals. As a result, rehabilitation therapy is being shifted from hospital-care to home-care. Several other countries will also face the same situation in the near future. Thus, we propose a tele-rehabilitation system combined...
ICTs are a critical enabler for a sustainable development that helps with unlocking human capabilities. Technology related to ageing belongs to several sustainable development targets and action lines: social inclusion, access to scientific knowledge, capacity building, cyber-security and ehealth. While the objective is the improvement of quality of life for citizens, a special monitoring is needed...
Current trends in telecommunication networks foresee the adoption of the fifth generation (5G) of wireless networks in the near future. However, a large number of people are living without coverage and connectivity. To face this issue, we consider the possibility of deploying 5G networks in rural and low-income zones. After detailing the current state-of-the-art, we consider the main challenges that...
Peak-to-average-power-ratio (PAPR) is an important parameter that affects the cost of end-user devices in next generation wireless networks. When PAPR is high, the end-user power amplifier's dynamic range should also be high, resulting in costly power amplifiers. Single-carrier frequency-division-multiple-access (SC-FDMA) is used as the air-interface in LTE-Advanced, and this paper proposes a novel...
