Sensing as a Service Model for Smart Cities Supported by Internet of Things

The world population is growing at a rapid pace. Towns and cities are accommodating half of the world's population thereby creating tremendous pressure on every aspect of urban living. Cities are known to have large concentration of resources and facilities. Such environments attract people from rural areas. However, unprecedented attraction has now become an overwhelming issue for city governance and politics. The enormous pressure towards efficient city management has triggered various Smart City initiatives by both government and private sector businesses to invest in ICT to find sustainable solutions to the growing issues. The Internet of Things (IoT) has also gained significant attention over the past decade. IoT envisions to connect billions of sensors to the Internet and expects to use them for efficient and effective resource management in Smart Cities. Today infrastructure, platforms, and software applications are offered as services using cloud technologies. In this paper, we explore the concept of sensing as a service and how it fits with the Internet of Things. Our objective is to investigate the concept of sensing as a service model in technological, economical, and social perspectives and identify the major open challenges and issues.Comment: Transactions on Emerging Telecommunications Technologies 2014 (Accepted for Publication

Efficient energy management for the internet of things in smart cities

The drastic increase in urbanization over the past few years requires sustainable, efficient, and smart solutions for transportation, governance, environment, quality of life, and so on. The Internet of Things offers many sophisticated and ubiquitous applications for smart cities. The energy demand of IoT applications is increased, while IoT devices continue to grow in both numbers and requirements. Therefore, smart city solutions must have the ability to efficiently utilize energy and handle the associated challenges. Energy management is considered as a key paradigm for the realization of complex energy systems in smart cities. In this article, we present a brief overview of energy management and challenges in smart cities. We then provide a unifying framework for energy-efficient optimization and scheduling of IoT-based smart cities. We also discuss the energy harvesting in smart cities, which is a promising solution for extending the lifetime of low-power devices and its related challenges. We detail two case studies. The first one targets energy-efficient scheduling in smart homes, and the second covers wireless power transfer for IoT devices in smart cities. Simulation results for the case studies demonstrate the tremendous impact of energy-efficient scheduling optimization and wireless power transfer on the performance of IoT in smart cities

Made-up rubbish: design fiction as a tool for participatory Internet of Things research.

As Internet of Things (IoT) technologies become embedded in public infrastructure, it is important that we consider how they may introduce new challenges in areas such as privacy and governance. Public technology implementations can be more democratically developed by facilitating citizen participation during the design process, but this can be challenging. This work demonstrates a novel method for participatory research considering the privacy implications of IoT deployments in public spaces, through the use of world building design fictions. Using three fictional contexts and their associated tangible design fiction objects, we report on findings to inform transparency and governance in public space IoT deployments

A JSON Token-Based Authentication and Access Management Schema for Cloud SaaS Applications

Cloud computing is significantly reshaping the computing industry built around core concepts such as virtualization, processing power, connectivity and elasticity to store and share IT resources via a broad network. It has emerged as the key technology that unleashes the potency of Big Data, Internet of Things, Mobile and Web Applications, and other related technologies, but it also comes with its challenges - such as governance, security, and privacy. This paper is focused on the security and privacy challenges of cloud computing with specific reference to user authentication and access management for cloud SaaS applications. The suggested model uses a framework that harnesses the stateless and secure nature of JWT for client authentication and session management. Furthermore, authorized access to protected cloud SaaS resources have been efficiently managed. Accordingly, a Policy Match Gate (PMG) component and a Policy Activity Monitor (PAM) component have been introduced. In addition, other subcomponents such as a Policy Validation Unit (PVU) and a Policy Proxy DB (PPDB) have also been established for optimized service delivery. A theoretical analysis of the proposed model portrays a system that is secure, lightweight and highly scalable for improved cloud resource security and management.Comment: 6 Page

The Internet of Things in Ports: Six Key Security and Governance Challenges for the UK (Policy Brief)

In January 2019, the UK Government published its Maritime 2050 on Navigating the Future strategy. In the strategy, the government highlighted the importance of digitalization (with well-designed regulatory support) to achieve its goal of ensuring that the UK plays a global leadership role in the maritime sector. Ports, the gateways for 95% of UK trade movements, were identified as key sites for investment in technological innovation. The government identified the potential of the Internet of Things (IoT), in conjunction with other information-sharing technologies, such as shared data platforms, and Artificial Intelligence applications (AI), to synchronize processes within the port ecosystem leading to improved efficiency, safety, and environmental benefits, including improved air quality and lower greenhouse gas emissions

Commoning the smart city: A case for a public Internet provision

As cities become more involved in data-driven processes of growth and governance, critical scholarship has highlighted the formidable issues around ownership, uses and the ethics of collecting, storing, and circulating such data. However, there has been less focus on the physical infrastructure as the ‘last mile’ problem for Internet access, between a revanchist perspective on the ‘broken Internet’ delivered by digital capitalism and the liberal rhetoric of the Internet as a human right. Through two case studies, the paper plots a pragmatic trajectory in the adoption of the Internet for people and ‘things’, in which city and users take different roles and responsibilities. It highlights benefits and challenges around the long-term sustainability and maintenance of the Internet as an infrastructure of the commons. An attention to ‘commoning’, instead, reveals the exclusionary or enabling practices the smart city might foster. Thus, the paper advocates for the direct involvement of the city and its citizens in maintaining and reproducing connectivity networks in the smart city
