The emergence and evolution of any package technology is driven by market trends as experienced by the end application. With the maturation of the mobile market, the trends for Smartphone and other mobile devices are more than ever for lower cost. Meanwhile, a higher degree of functionality and performance, thinner profile, and longer battery life are some of the additional market drivers seen in...
We present cooperative moving object tracking with multiple mobile sensor nodes, each equipped with a multilayer laser scanner. Moving objects in the laser-scanned images are detected by a binarized occupancy grid method. The sensor nodes send the information of the detected moving objects to a central server, which estimates the size, position, and velocity of those objects using a Bayesian filter...
This paper aims at using the novel concept of LTE-based Device-to-Device communications (D2D) as a new alternative for Intelligent Transportation Systems (ITS) vehicular communications in advanced 4G networks and beyond. We propose the Cellular Vehicular Network (CVN) solution as a reliable and scalable operator-assisted opportunistic architecture that supports hyper-local ITS services as 3GPP Proximity...
Intelligent Transportation Systems have been instrumental in reshaping transportation towards safer roads, seamless logistics, and digital business-oriented services under the umbrella of smart city platforms. Broadcasting transmission is an essential operational technique that serves a broad range of applications which demand different restrictive QoS provisioning levels. Although broadcast communication...
Providing Internet access on buses allow people to read news, check emails, watch sport games, and hence can greatly improve the quality of people's life. This paper proposes an adaptive routing protocol, called R-BUS for a bus network. R-BUS selects a route based on the link's lifetime and its communication signal quality. The protocol takes the bus mobility and the radio propagation model into account...
Vehicular wireless networks are prospective tools which contribute to safer and more efficient roads. Therefore, they require the design and development of new communication protocols that should constitute the building blocks of future vehicular communication architecture. Many works have been carried out in this wide research area. In this paper, we propose a reliable distance-based broadcast protocol...
In spite of the importance of the stability and reliability of the embedded system, and the difficulty of its development, the embedded system needs to be released on the market quickly by minimizing the development period. The prototyping development methodology is being widely used to minimize the development cost of the embedded product. In this study, the prototyping developmental tools RapidPLUS[1]...
The field of electronic noses and gas sensing has been developing rapidly since the introduction of the silicon based sensors. There are numerous systems that can detect and indicate the level of a specific gas. We introduce here a system that is low power, small and cheap enough to be used in mobile robotic platforms while still being accurate and reliable enough for confident use. The design is...
This paper describes a research of maintenance system and development of new control and operation diagnostics of KT4 type trams in Tallinn (Estonia). System operation modes and diagnostic methods were studied during hard and software development of trams. Also it gives a short overview of used methods, integrations problems and profitability calculation
The 802.11-p based dedicated short range communication (DSRC) is being seriously considered as a promising wireless technology for enhancing transportation safety and highway efficiency. However, to-date, there is very little research done in characterizing the reliability of DSRC communication based on real-world experimental data, and its effect on the reliability of vehicle safety applications...
