Reducing the Amount of Small Data Communication for Telematics Services

Abstract

It is predicted that many more consumers will use free telematics smartphone applications, given their increased availability. These telematics services require that servers and consumer devices, such as smartphones and car navigation terminals, transmit large amounts of small data through uplink. Developing methods to decrease the data size that is transmitted is one of the most significant issues in this field because of the cost of transmission for consumers and service providers. In this paper, we propose a new data compression method for application to telematics technology, which deletes redundant data and applies an appropriate compression method for a given situation. We evaluated the proposed method and report positive results.
