Abstract
애드 혹 네트워크에서 반딧불 영감을 받은 접근 방식을 사용하는 분산 타이밍 동기 기술을 연구한다. 노드가 직교주파수분할다중접속 무선 인터페이스에서 통신하는 패킷 기반 통신을 하는 다중 반송파 시스템에 잘 적용될 수 있도록, 펄스의 결합진동자 이론에 기반한 반딧불 동기 알고리즘을 재조명한다. 주요 결과로써, 네트워크 내 노드 수 및 네트워크 위상과 같은 다양한 네트워크 변수가 주어질 때, 타이밍 동기화 시간을 최소화 하는 방식에서 결합함수 및 검파 임계값을 최적 설계함으로써 새로운 동기 코드 검파기를 소개한다. 실제적인 네트워크 환경에서 동기 상태로의 수렴을 보이기 위해 컴퓨터 모의실험을 수행한다.
