Target classification is an important enabling technology for the monitoring task in transportation sensing networks. In the paper the magnetic signal and seismic acceleration signal are collected, analyzed and transmitted for a mobile road target. A classification algorithm based on the sensor network is proposed, which adopts a peak and valley pattern of hybrid detection signals from different sensors...
Intelligent traffic information service (ITIS) is a typically grid application in ShanghaiGrid to achieve effective traffic management. Several issues and challenges needed to be explored in ITIS, such as resource sharing, middleware communication, traffic control grid, and so on. We implemented a prototype system of ITIS and carried out a field testing in Shanghai city. We show that by utilizing...
An intelligent transportation system aims to make roads safer and less congested. Compared to traditional sensor networks, this recently emerged sensor network is not restricted by the power supply and the storage space. These sensors are equipped with GPS devices and large amount flash memory cards. Under such environment, an effective and efficient architecture for data collection and data exchange...
Today vehicle theft rate is very high, thus tracking/alarming systems are being deployed with an increasingly popularity. These systems however bear some limitations such as high cost, high false-alarm rate, and easy to be disabled. This paper describes the design, implementation and evaluation of a Sensor-network-based Vehicle Anti-Theft System (SVATS) to address these limitations. In this system,...
With the adoption of state-of-the-art telecommunication technologies for sensing and collecting traffic related information, Vehicular Sensor Networks (VSNs) have emerged as a new application scenario that is envisioned to revolutionize the human driving experiences and traffic flow control systems. To avoid any possible malicious attack and resource abuse, employing a digital signature scheme is...
Wireless sensor networks can enable the reliable information gathering and transmission for a variety of applications that range from environment protection and civil structure monitoring to battlefield surveillance. This paper presents an innovate detecting system based on wireless sensor networks for detecting occupancy of vehicle berth in car park The battery-powered wireless sensor nodes can be...
