Abstract

Due to frequent topology changes in wireless networks, inter-node link disconnection and path re-establishment occur, causing problems such as overloading control messages in the network. In this paper, to solve the problems such as link disconnection and control message overload, we perform path setup in three steps of the neighbor node discovery process, the route discovery process, and the route management process in the wireless network environment. The link stability value is calculated using the information of the routing table. Then, when the zone master monitors the calculated link value and becomes less than the threshold value, it predicts the link disconnection and performs the path reset to the corresponding transmitting and receiving node. The proposed scheme shows a performance improvement over the existing OLSR protocol in terms of data throughput, average path setup time, and data throughput depending on the speed of the mobile node as the number of mobile nodes changes.

무선 네트워크에서 토폴로지의 빈번한 변화로 노드 간 링크 단절과 경로재설정이 발생하여 네트워크 내에 제어메시지 과부하와 같은 문제점들이 발생한다. 본 연구에서는 링크 단절과 제어 메시지 과부하와 같은 문제점을 해결하기 위하여 무선 네트워크 환경에서 주변 노드 탐색과정, 경로 탐색과정, 경로 관리과정의 3단계로 경로 설정을 수행하고 경로 관리 과정에서 존 마스터가 수집한 라우팅 테이블의 정보를 이용하여 링크 안정성 값을 산출한다. 그리고 산출 된 링크 값을 존 마스터가 모니터링 하여 임계 값 이하로 되면 링크 단절로 예측하고 해당 송수신 노드에게 경로 재설정을 수행하게 된다. 제안한 기법은 이동 노드 수 변화에 따른 데이터 처리량, 평균 경로 설정 시간 및 이동 노드의 속도 변화에 따른 데이터 처리량에서 기존의 OLSR 프로토콜보다 성능 향상을 나타내었다.
