Abstract

AVLS is nowadays pretty considered on one of important parts in telematics service with a computerization of vehicle. However, with an implementation of commercial OS, individual OS and firmware on AVLS terminals, the cost and developing period are significantly increased. In this paper, we present the effective log-file creation methode about automobile status and location information within a restricted memory through designing AVLS terminals based on embedded linux. The proposed method shows 0.8% better performance on bzip2 compressor comparing to gzip compressor in the compressibility. In addition, bzip2 is faster than gzip about 2.14 times in the speed of compression.
