1.Cognitive Radio & Networks in Intelligent Vehicle Systems (IVS) and High Speed Rail (HSR) Applications: Challenges and Opportunities,
Dr. T. Russell Hsing, FIEEE, FBCS (UK), FSPIE
With the recent advance in Cognitive Radio, the use of wireless spectrum is getting more and more efficient. Each vehicle (or high-speed rail train) will become a unique moving-node in the entire global communications network. Many new telematics services could be offered through these emerging technologies. The networks infrastructure will support more economic and effective interactions between the automobiles (or the HSR trains) and also with the surrounding environment, through both wireless access and wire line based networking infrastructure. Those potential services and applications include safety, health and status of the automobile (or HSR train), location-based user services, passenger entertainment, and more efficient use of the transportation, wireless spectrum and communications infrastructure. The speakers will present their view on the potential challenges and opportunities of using cognitive radio in Intelligent Vehicle Systems (IVS) and High Speed Rail (HSR) Train applications during this talk. This talk will address how such a vast service and network systems can be scaled, supported, made reliably and economically. Important issues such as the maturity of the technology, the value of the services performed the complex regulatory regime and standards, the adequate business models and rationale for creating such networks will be presented.
2.Foundations of Network Localization and Location-Based Services
Professor Moe Win, FAAAS, FIEEE, FIET, Laboratory for Information and Decision Systems (LIDS), Massachusetts Institute of Technology
The availability of positional information is of great importance in numerous commercial, health-care, public safety, and military applications. The coming years will see the emergence of high-definition location-aware (HDLA) networks with sub-meter accuracy, minimal infrastructure, and robustness in harsh environments. We propose to realize this vision using a combination of wide bandwidth transmission and cooperative techniques. This talk presents a brief technical overview of our recent activities with particular emphasis on network localization employing wideband wireless technology from three points of view: fundamental performance bounds, cooperative algorithms, and experimentation. Fundamental bounds serve as performance benchmarks and as guidelines for network design. Cooperative algorithms will be designed to approach these bounds, resulting in dramatic performance improvements over traditional techniques. Experimentation will be used to determine important attributes of physical environments; these realistic models are necessary to obtain accurate bounds, to develop robust algorithms, and to validate their performance in harsh environments. |
