For some time, we have been working toward the “Realization of a Safe and Secure Society using ICT in Shiojiri-City, Nagano Prefecture.” This is a project comprised of two phases: information gathering, and dissemination of information. For information gathering, we are developing systems to confirm the whereabouts of children and the elderly, who are vulnerable in disasters, and systems to gather...
This work presents a wireless sensor platform implemented on a UWB time-coded semi-passive RFID tag. Several sensors are integrated in the tag, connected to its microcontroller either by means of an analog-to-digital converter or using an I2C bus. An EEPROM memory is also connected to the I2C bus to store measurements. The sensor is normally in sleep mode and only wakes up when the reader contacts...
To sustain its largely urban population, China has invested heavily in making its digital cities smart, and with more than 200 pilot smart cities, has the opportunity to explore technology, apply lessons to future development, and refine conceptions of what such cities require.
A Wireless Sensor Network (WSN) is a key data provider for the Internet of Things (IoT). A WSN can serve as a tool for both identification and data generation. However, due to its inherent resource limitation the WSNs cannot generate and transmit large data streams and, therefore, typically transmit raw and simple sensor values. Furthermore, the sensors usually transmit their data in proprietary formats...
Smart City concept and applications domains are taking a prominent position in nowadays innovation trends. Future Internet and ICT in general are considering the Smart City as the key concept for the future technological developments. In particular, Wireless Sensor Networks (WSN) and Machine to Machine (M2M) communications are some of the basic enablers for fulfilling the Smart City concept requirements...
Based on the “digital city”, “smart city” is widely used in daily livelihood, environmental protection, public security, city services and other fields. In this paper, we mainly focus on recent research and the concept of “smart city”, summarizing the relationship between "smart city" and "digital city", putting forward the main content of application systems as well as the importance...
