International Journal of Vehicular Technology , 2011, DOI: 10.1155/2011/853948
Abstract: The important innovations in wireless and digital electronics will support many applications in the areas of safety, environmental and emissions control, driving assistance, diagnostics, and maintenance in the transport domain. The last few years have seen the emergence of many new technologies that can potentially have major impacts on transportation systems. One of these technologies is Wireless Sensor Networks. A wireless sensor device is typically composed of a processing unit, memory, and a radio chip which allows it to communicate wirelessly with other devices within range. The Embedded Middleware in Mobility Applications (EMMA) project delivers a middleware that aims to facilitate the interaction between sensing technologies in transportation systems. This paper outlines our experience in the EMMA project and provides an illustration of the important role that wireless sensor technology can play in future transportation system. The paper discusses our experience of using heterogeneous sensors to develop transportation system applications in the EMMA project and focuses on how cooperation between vehicle and infrastructure can be addressed. It also presents encouraging results obtained from the experiments in investigating the feasibility of utilising wireless sensor in vehicle and vehicle-to-infrastructure communication in real transportation applications. 1. Introduction A recent study by the UK Government’s Office of Science and Innovation, which examined how future intelligent infrastructure would evolve to support transportation over the next 50 years, looked at a range of new technologies, systems, and services that may emerge over that period [1, 2]. One key class of technology that was identified as having a significant role in delivering future intelligence to the transport sector is Wireless Sensor Networks (WSN) and in particular the fusion of fixed and mobile networks to help deliver a safe, sustainable, and robust future transport system based on the better collection of data, its processing and dissemination, and the intelligent use of the data in a fully connected environment. As future intelligent infrastructure will bring together and connect individuals, vehicles and infrastructure through wireless communications, it is critical that robust communication protocols are developed. Mobile wireless ad-hoc networks (MANETs) are self-organising networks where nodes exchange data without the need for an underlying infrastructure [3]. MANETs have attracted extraordinary attention from the research community in recent years including in
Fuzzy Mobile-Robot Positioning in Intelligent Spaces Using Wireless Sensor Networks  [PDF]

Sensors , 2011, DOI: 10.3390/s111110820
Abstract: This work presents the development and experimental evaluation of a method based on fuzzy logic to locate mobile robots in an Intelligent Space using Wireless Sensor Networks (WSNs). The problem consists of locating a mobile node using only inter-node range measurements, which are estimated by radio frequency signal strength attenuation. The sensor model of these measurements is very noisy and unreliable. The proposed method makes use of fuzzy logic for modeling and dealing with such uncertain information. Besides, the proposed approach is compared with a probabilistic technique showing that the fuzzy approach is able to handle highly uncertain situations that are difficult to manage by well-known localization methods.

Abstract: The aim of this work was to position a Mobile Robot in an Intelligent Space, and this paper presents a sensorial system for measuring differential phase-shifts in a sinusoidally modulated infrared signal transmitted from the robot. Differential distances were obtained from these phase-shifts, and the position of the robot was estimated by hyperbolic trilateration. Due to the extremely severe trade-off between SNR, angle (coverage) and real-time response, a very accurate design and device selection was required to achieve good precision with wide coverage and acceptable robot speed. An I/Q demodulator was used to measure phases with one-stage synchronous demodulation to DC. A complete set of results from real measurements, both for distance and position estimations, is provided to demonstrate the validity of the system proposed, comparing it with other similar indoor positioning systems.

Abstract: Intelligent transportation clouds could provideServices such as autonomy, mobility, decision support and thestandard development Environment for traffic managementstrategies, and so on. With mobile agent technology, anurban-traffic management system based on Agent-BasedDistributed and Adaptive Platforms for Transportation Systems(Adapts) is both feasible and effective. However, the large-scaleuse of mobile agents will lead to the emergence of a complex,powerful organization layer that requires enormous computingand power resources. To deal with this problem, we propose aprototype urban-traffic management system using multi agentbased intelligent traffic clouds. Cloud computing can help us tohandle the large amount of storage resources and masstransportation of data effectively and efficiently.

Abstract: Technological innovations in the field of disease prevention and maintenance of patient health have enabled the evolution of fields such as monitoring systems. One of the main advances is the development of real-time monitors that use intelligent and wireless communication technology. In this paper, a system is presented for the remote monitoring of the body temperature and heart rate of a patient by means of a wireless sensor network (WSN) and mobile augmented reality (MAR). The combination of a WSN and MAR provides a novel alternative to remotely measure body temperature and heart rate in real time during patient care. The system is composed of (1) hardware such as Arduino microcontrollers (in the patient nodes), personal computers (for the nurse server), smartphones (for the mobile nurse monitor and the virtual patient file) and sensors (to measure body temperature and heart rate), (2) a network layer using WiFly technology, and (3) software such as LabView, Android SDK, and DroidAR. The results obtained from tests show that the system can perform effectively within a range of 20 m and requires ten minutes to stabilize the temperature sensor to detect hyperthermia, hypothermia or normal body temperature conditions. Additionally, the heart rate sensor can detect conditions of tachycardia and bradycardia.

Abstract: Mobile devices are rapidly becoming the primary computing device in people's lives. Application delivery platforms like Google Play, Apple App Store have transformed mobile phones into intelligent computing devices by the means of applications that can be downloaded and installed instantly. Many of these applications take advantage of the plethora of sensors installed on the mobile device to deliver enhanced user experience. The sensors on the smartphone provide the opportunity to develop innovative mobile opportunistic sensing applications in many sectors including healthcare, environmental monitoring and transportation. In this paper, we present a collaborative mobile sensing framework namely Mobile Sensor Data EngiNe (MOSDEN) that can operate on smartphones capturing and sharing sensed data between multiple distributed applications and users. MOSDEN follows a component-based design philosophy promoting reuse for easy and quick opportunistic sensing application deployments. MOSDEN separates the application-specific processing from the sensing, storing and sharing. MOSDEN is scalable and requires minimal development effort from the application developer. We have implemented our framework on Android-based mobile platforms and evaluate its performance to validate the feasibility and efficiency of MOSDEN to operate collaboratively in mobile opportunistic sensing applications. Experimental outcomes and lessons learnt conclude the paper.

Abstract: The integration of communication protocols into transport systems is a much adored research area today. Much of seminal work has been reported on the topic of intelligent transportation systems (ITS) in the recent years. Many advanced techniques have been garnered to improve online communication and to promote the security, comfort, and efficiency of ITS. Of primary importance to the effective application of ITS is the communication protocol used. A fascinating development is that the yesterday's Global System for Mobile Communication protocol is being replaced by the Universal Mobile Telecommunication System protocol, which is the third-generation mobile technology. This article attempts to identify a suitable communication system for ITS applications. It is impracticable to substantially modify the original UMTS-IMS-AKA protocol which is in practice because it can disturb the operation of the current system, and thus we explore other possibilities through this research. We investigate a novel protocol to make the original UMTS-IMS-AKA protocol compliant with ITS as well as adaptable into the current UMTS protocol.

Abstract: In order to better analyze dynamic transportation flow so as to gain road traffic information, this paper combined the Internet of Things technology and the intelligent transportation system and proposed a new intelligent transportation detection system-IhFDS(Intelligent Transportation Flow Detection System Based on Internet of Things).ITFDS obtains original traffic parameters and initial data fusion by vehicle sensor nodes. The sink is the central node for information gathering, distribution and secondary data fusion, and the center engine room is responsible for statistics and management. Simulation results show ITFDS can effectively and timely obtain the value of road transportation flow and send it to the vehicle,based on which travel routes can be selected.
