모바일 환경에서 지도 서비스를 위한 효율적인 공간 데이터 캐시 알고리즘

다국어 초록 (Multilingual Abstract)

Recently, the interests of mobile GIS technology is increasing with the spread of wireless network, the improvement of mobile device’s performances, and the growth of demands about mobile services. Providing services in a wireless environment with existing wired-based GIS solutions have many limitations such as slow communication, processing rates and screen size. In this paper, we propose a cache algorithm on client side to solve the above problems. The proposed algorithm demonstrates the performance improvement over known studies by utilizing unit time and spatial proximity. In addition, this paper conducts a performance evaluation to measure the improvement in algorithm efficiency and analyzes the results of the performance evaluation. When spatial data queries are conducted, according to our performance evaluation, hit rate has been improved over the existing algorithms.
