2008 Ninth ACIS International Conference on Software Engineering, Artificial Intelligence, Networking, and Parallel/Distributed Computing
Design of a Network Coverage Analyzer for Roadside-to-Vehicle Telematics Networks
August 06-August 08
ISBN: 978-0-7695-3263-9
This paper designs a connectivity analysis scheme for the roadside-to-vehicle telematics network based on the real movement history of vehicle objects collected from taxi telematics system currently in operation, aiming at providing a useful guideline and information to build a telematics network.The implemented analyzer can locate the current and previous positions??of all vehicles, decide whether it can be connected to an RSU, and calculate the duration of disconnected state, taking into account the transmission range, the number of RSUs, and RSU deployment. The RSU placement scheme can improve the network coverage exploiting the analysis result. The experiment??result shows that each time the transmission range increases by 100 $m$, with an appropriate overlap ratio setting, the network coverage is improved by about 10 % and that the larger the transmission distance, the earlier the coverage meets the local maximum according to the overlap ratio.
