Abstract

Smart devices linked to high speed networks enable us to obtain location dependent data at anywhere and anytime. In this environment, a wireless data broadcast system can deal with enormous data request from a great number of clients effectively. In order to set up an efficient wireless data broadcast system, various data scheduling and indexing schemes have been proposed. However, a simulation framework to evaluate the schemes is not reported yet. In this paper, we design and develop a simulation framework for a wireless data broadcast system. The developed simulation framework can evaluate quickly a wireless data broadcast system and has scalability to adopt various data scheduling and indexing schemes for wireless data broadcasting.

스마트폰과 초고속 네트워크에 연결된 스마트폰과 같은 클라이언트는 다양한 위치기반 서비스를 언제 어디서나 사용할 수 있게 해주고 있다. 이런 환경에서 무선 데이터 방송 시스템은 대규모의 클라이언트들의 다양한 데이터 요구를 효과적으로 처리할 수 있게 한다. 효율적인 무선 데이터 방송 시스템을 구축하기 위해 다양한 데이터 스케줄링 기법과 인덱싱 기법이 개발되고 있으나 이러한 기법들을 신속히 평가하기 위한 시뮬레이션 프레임워크의 개발은 보고된 것이 없다. 본 논문에서는 시뮬레이션 기반의 무선 데이터 방송 시스템 성능 평가를 위한 시뮬레이션 프레임워크를 설계 및 구현한다. 개발된 프레임워크는 무선 데이터 방송 시스템의 성능을 빠르게 평가할 수 있으며 다양한 데이터 스케줄링 기법과 인덱싱 기법을 적용할 수 있는 확장성을 가진다.
