Internet of Things (IoT) describes a world where everyday objects are always connected to the Internet, allowing them to communicate and interact with each other. By connecting these everyday objects to the Internet and making them available everywhere at any time, IoT allows to remotely monitor, manage, and gather status information about them and their surrounding environment. IoT is a revolutionary...
This paper presents a sound collection system that uses crowdsourcing to gather information for visualizing area characteristics. First, we developed a sound collection system to simultaneously collect physical sounds, their statistics, and subjective evaluations. We then conducted a sound collection experiment using the developed system on 14 participants. We collected 693,582 samples of equivalent...
Mobile Crowd Sensing (MCS) is an emerging paradigm that exploits the ubiquity of smartphones and cheap sensor devices to collect data and thus contribute to the provision of useful services, especially in the domains of urban life. While many MCS implementations have been proposed for different applications, the lack of common performance metrics means that their efficiency cannot be easily compared...
The futuristic smart cities must have the capabilities to withstand the growing challenges on the urban infrastructure in terms of public safety, resource management, co-operative mobility management and more. To tackle these challenges, the cities are increasingly using next generation information and communication technologies (ICT). A plethora of the ICT based innovations are taking place on a...
The aim of this paper is to propose a fault-tolerant smart system which can render, track and monitor the process of attendance of students. A smart attendance system is refined in a systematic manner where the students enter the lecture hall with an android device which possesses a beacon compatible mobile app. The main purpose of this system is to minimize the power consumption of Bluetooth using...
In smart city, all kinds of users’ data are stored in electronic devices to make everything intelligent. A smartphone is the most widely used electronic device and it is the pivot of all smart systems. However, current smartphones are not competent to manage users’ sensitive data, and they are facing the privacy leakage caused by data over-collection. Data over-collection, which means smartphones...
Although various smart city projects are launched in all over the world, it is not obvious how to tailor the existing IoT and self-aware technologies for individual services, systematically. One of the reason is due to the lack of common view that can be used to investigate various smart city services across different domains. This paper proposes a domain-neutral execution model and an integrated...
Multi-core System On Chips (SoCs) are playing a predominating role in smart phones and tablets. Unlike traditional multi-core desktops, mobile devices are restricted by the limited energy the batteries can buffer. It remains unclear whether it is energy efficient to adopt heterogeneous computing in multi-core mobile devices. In this paper, we evaluate mobile heterogeneous computing by benchmarking...
In this paper, we discuss key findings, technological challenges and socioeconomic opportunities in Smart City era. Most of the conclusions were gathered during SmartSantander project, an EU project that is developing a city-scale testbed for IoT and Future Internet experimentation, providing an integrated framework for implementing Smart City services.
