Core Application Technology for Telematics in USN Enviroment

With the rapid progress in wireless communication and sensor technologies, it becomes possible to equip vehicles with multiple communication devices and sensors. Even though CDMA remains the most popular communication environment for LBS and telematics, other alternatives, such as MANETs (Mobile Ad-hoc Network) and DMB (Digital Multimedia Broadcasting), are of interest. This project studies the feasibility of MANETs and sensor networks for telematics applications. The project aims to (1) conduct a feasibility study on MANETs and sensor networks for safety control at intersections, and to (2) uncover theoretical foundations of database systems for vehicles in diverse communication environments.
