This paper reports on a study of energy consumption for data storage in data centres. Unlike previous estimates, which have been extrapolations of broad energy usage within the data centre, we take a bottom-up approach. We show that the growth in energy consumption can be mitigated somewhat by adopting a more aggressive policy of data archiving on long-term, low-energy, ?cold? storage; or more ideally purging data of little or no future value.
Following a review IoT applications, the communications and networking technologies that can potentially support large scale deployment of IoT systems for different industrial, business and social applications are discussed. The paper then concentrates on wireless networking technologies for IoT systems with specific focus on deployment issues. The deployment discussion concentrates on different IoT systems QoS and networking requirements, cost, coverage area and energy supply requirements. We introduce a sustainable low cost heterogeneous network design using short range radio standards that can be used to develop wide area networks to support large number of IoT devices for various applications. Finally the paper makes some general recommendations towards sustainable network design techniques for future IoT systems that can reduce the OPEX and CAPEX requirements.
This article explores the context and potential offered by the growth of the Internet of Things (IoT). It provides an overview of this next phase of the digital revolution that is underpinned by the growth of the social web, web 2.0, and the convergence of technologies such as mobile and ubiquitous broadband. It also attempts to provide some insight into the potential value of the Internet of Things market in the future.
Alcatel-Lucent?s visiting Strategic Marketing Director, Customer and Market Insight ,Marc Jadoul will deliver a public lecture on IoT and Smart Cities at the University of Melbourne.
A panel of experts chaired by Professor Rod Tucker on the Internet of Things. According to 2014 IDC estimates, there are already more than 50 billion globally connected sensors that can track, monitor and feed data to computerised systems. IDC foreshadows that by 2020 there will be more than 200 billion sensors generating an estimated 10% of data in what will be a 44 Zettabyte (1021) digital universe.
CPUs that cost thousands a decade ago now cost just a few dollars. The Arduino platform has lowered barriers to entry so that people with minimal technical knowledge can create special purpose computers capable of changing the world.
