A Presence-Based Architecture for a Gateway to Integrate Vehicular Ad-Hoc Networks (VANETs), the IP Multimedia Subsystems (IMS) and Wireless Sensor Networks (WSNs)

Résumé Le IP Multimedia Subsystems (IMS) est un sujet de recherche qui attire l’attention de la communauté de recherche. Il a comme but de fournir un accès mobile aux différents services internet. Il s’agit d’une architecture de contrôle au-dessus de la couche IP dont le but est de fournir une qualité de service, services intégrés et un système de tarification équitable à travers des interfaces standards. D’autre part, le réseau Ad-hoc de véhicules (VANETs) fournit un nouveau moyen de communication sans-fil entre les véhicules circulants à grande vitesse ainsi que les équipements installés tout au long des côtés de la route. Cette technologie ouvre la porte pour développer des applications diverses comme la génie de trafic, gestion du trafic, diffusion d’information en cas d’urgence pour éviter des situations critiques, divertissement et bien d’autres choses. VANETs forme une sous-classe des réseaux Ad-hoc mobile dont la performance est fortement liée au protocole de routage utilisé dans le réseau. L’intégration des deux technologies, IMS et VANET, permettra de mettre en œuvre de nouveaux services multimédias. Ce mémoire de maîtrise propose une architecture d’une passerelle incorporant ces deux technologies ensemble. Étant donné que les deux architectures utilisent des formats de communication différents, on a conçu un middleware afin d’adapter le format en fonction de la destination et de choisir la meilleur stratégie de livraison d’information entre eux. La passerelle, qui est le cœur de notre architecture, est une couche au-dessus du IMS et le VANET. ----------ABSTRACT On one hand, IP Multimedia Subsystems (IMS) are a research area that has been gaining attention from the research community. It aims to provide cellular access to all Internet services. It is a control architecture on the top of the IP layer whose goal is dependent on the provision of the Quality of Service (QoS), integrated services and fair charging scheme throughout standard interfaces. On the other hand, Vehicular Ad-hoc Networks (VANETs) are a new communication paradigm that enables the wireless communication between vehicles moving with high speeds, as well as the vehicles and the road side equipments found along the roads. This opened the door to develop several new applications like, traffic engineering, traffic management, dissemination of emergency information to avoid critical situations, comfort and entertainment and other user applications. Moreover, VANETs are a sub-class of mobile ad-hoc networks; the performance of the communication depends on how better the routing takes place in the network. Routing of data depends on the routing protocols being used in the network. Combining the capabilities of IMS world with the VANET world opens the door to deploy a wide range of novel multimedia services. This dissertation proposes a presence-based architecture for the integration of IMS with VANETs. The presence of the middleware is used to make an instantaneous awareness of the VANETs changes as well as of the IMS format and to select the best delivery strategy between the two architectures. The gateway which is the heart of our architecture is an overlay built on the top of the IMS as well as the VANETs

The growing trend to provide communication among the vehicles on the road has provided the opportunities for developing a variety of applications for VANET. The unique characteristics of VANET bring about new research challenges

A Performance Review of Intra and Inter-Group MANET Routing Protocols under Varying Speed of Nodes

Mobile Ad-hoc Networks (MANETs) are a cluster of self-organizing and self-governing wireless nodes without any backbone infrastructure and centralized administration. The various nodes in MANET move randomly, and this node mobility may pose challenges on the performance of routing protocols.  In this paper, an Intra and intergroup performance review of various MANET routing protocols are performed under varying speed of nodes. The routing protocols included in this study are reactive, proactive, and hybrid protocols. This performance review is done using the NS2 simulator and random waypoint model. The routing protocols performance is assessed through standard performance measure metrics including packet delivery ratio, throughput, routing overhead and end to end delivery with varying speed of nodes. The simulations result shows that there is no significant impact of varying speed of nodes on standard performance evaluation metrics

Development of wireless prototype vehicle speed monitoring system.

Globally road accident is considered to be an important issue, which can be reduced by proper vehicle speed monitoring system. More recently, the advancement in wireless sensor technology shows a great promise in designing Intelligent Transportation System (ITS) due to its flexibility and cost-effectiveness for deployment. The aim of this research is to develop a prototype vehicle speed monitoring system using accelerometer-based wireless sensor. The basic concept of the system is based on the following methodology: developing an experimental system to generate random speed data, which can represent vehicle speed on the road and developing a software to monitor and manage the speed data wirelessly. A wireless sensor attached with a mechanical wheel measures the acceleration vibration of the system, which is equivalent to wheel speed and transmits the data wirelessly to a computer. A software (SpeedManage) has been developed using Java Socket programming codes which converts the vibration data to equivalent speed data and presents these in a Graphical User Interface (GUI). If the detected speed is greater than a set speed limit, the data will be automatically saved in a central database in the form of an electronic report for taking any further action. The functionality of the system has been simulated in a laboratory environment by setting different speed limits for monitoring single or multiple vehicle speed scenarios through appropriate algorithm and code development. The graphical user interface (GUI) of the software continuously presents the vehicle speeds with time and the overspeeding conditions are indicated. The speed details are also continuously updated on the left hand side of the GUI. The system is also capable of generating an automatic electronic report for a simulated speeding vehicle with vehicle number, speed details, time etc. Therefore, based on the performance of prototype system, it can be concluded that sensor-based vehicle speed monitoring system has great potential for monitoring vehicle speed wirelessly. SpeedManage software should help to effectively, automatically and intelligently monitor vehicle speed

Embedded System for Construction Material Tracking Using Combination of Radio Frequency and Ultrasound Signal

This study created a framework for integrating the latest innovations in wireless sensor network that automate tracking and monitoring construction assets, e.g. equipment, materials, and labor in construction sites. This research constitutes one of the few studies to incorporate emerging information and sensor network technologies with the construction industry, which has been slow to migrate away from legacy processes. The presented research works introduce a new prototype framework of an automated tracking system that will address the needed shift from the time-and labor-intensive legacy systems to sensor- and network-based collaboration and communication systems for construction processes. Software and hardware architecture for the new tracking system was developed using the combination of ultrasound and radio signals. By embedding the external ultrasound device with a MICAZ platform, enhancements to networking flexibility and wireless communication was observed over the previous technologies used in the construction material tracking systems. Feasibility study and testbed experiment on the position estimation were implemented to verify the localization algorithm presented in this dissertation. Cost benefit analysis based on quantitative approach implied that the presented framework can save the implementation cost of material tracking by up to 64 percent in a typical construction project. In addition to cost savings, the use of sensor-based tracking system can provide the intangible, comprehensive benefits in communication, labor utilization, document management, and resource management. It is hoped that the present work will describe a system that can effectively be used in a range of applications for tracking and monitoring purposes and will present a clear path that engineers can take to use existing wireless sensor technology in their particular applications. The cost of such hardware will decrease rapidly, thereby permitting large numbers of application scenarios to be possible in many construction sites with improved energy consumption, hardware performance, durability, and safety

SNIP: A Sensor Node-Initiated Probing mechanism for opportunistic data collection in sparse wireless sensor networks

In many potential wireless sensor network applications, the cost of the base station infrastructure can be prohibitive. Instead, we consider the opportunistic use of mobile devices carried by people in daily life to collect sensor data. As the movement of these mobile nodes is by definition uncontrolled, contact probing is a challenging task, particularly for sensor nodes which need to be duty-cycled to achieve long life. We propose a Sensor Node-Initiated Probing mechanism for improving the contact capacity when the duty cycle of a sensor node is fixed. In contrast to existing mobile node-initiated probing mechanisms, in which the mobile node broadcasts a beacon periodically, in SNIP the sensor node broadcasts a beacon each time its radio is turned on according to its duty cycle. We study SNIP through both analysis and network simulation. The evaluation results indicate that SNIP performs much better than mobile-initiated probing. When the fixed duty cycle is lower than 1%, the probed contact capacity can be increased by an order of 2-10; alternatively, SNIP can achieve the same amount of probed contact capacity with much less energy consumption
