Efficient transmission of geographic information using streaming technology
Yoo, JaeJun ... [et al.]
Recently, as some services using geographic information or spatial data such as telematics or LBS (Location Based Service) have been being more diverse and complex and mobile devices such as PDA (Personal Digital Assistance) or several telematics terminals have been being used more widely, efficient transmission of geographic information is being more important, especially in wireless environment. To make data transmission more efficient in such geographic services, several enhancements are proposed and are being researched. One of basic concepts which those enhancements are based on is streaming. Transmitting geographic information using streaming mechanism can be designed and implemented in several levels according to granularity of data to be transmitted. For example, a file or a specific region based on several criteria can be the granularity. In this paper, we suggest a novel and efficient transmission method based on streaming mechanism of which transmission unit is a block or a page. To do this, we 1) introduce the concept of data streaming which is tightly coupled to operating system, 2) design and implement the streaming system and 3) conduct simple experiments to show the performance of the implemented system.
