Abstract
본 논문에서는 기기 간 직접(device-to-device) 통신 시스템에서 근접한 디바이스의 모바일 어플리케이션 및 서비스를 발견하기 위한 디스커버리 프로토콜을 제안한다. 기기 간 직접통신 기술을 기반으로 모바일 소셜네트워크,모바일 마케팅 등의 근접 기반 어플리케이션을 실현할 수 있다. 이를 위해 우선적으로 주변에 있는 수많은 디바이스에서 원하는 어플리케이션을 찾아내는 디스커버리 프로토콜의 설계가 필수적이다. 기반 시설이 없는 에드혹 망에서 디스커버리 프로토콜을 구현하기 위해서는 디바이스 내부의 어플리케이션 정보를 축약해서 디스커버리 코드를 생성하고 이를 주기적으로 방송하는 방법을 쓸 수 있다. 본 논문에서는 해시함수 및 블룸필터(Bloom filter)를이용하여 디스커버리 프로토콜을 설계하고 이의 성능을 수학적으로 분석한다.
