멀티홉 무선 Ad Hoc 네트워크는 페이딩으로 인해 일시적인 링크 오류가 발생합니다. 패킷 전송 신뢰성을 향상시키고 페이딩 환경에서 효율적인 전송을 달성하기 위해, 크로스 레이어 접근 방식과 로컬 노드의 인지 행동을 기반으로 새로운 인지 임시 우회 기법을 제안합니다. 제안된 방식은 인접 노드들이 손실된 패킷에 대한 임시 우회를 준비하고 생성할 수 있도록 해준다. 이는 다중 홉 경로 및 링크 승인 정보가 포함된 메시지 패킷을 모니터링하여 수행됩니다. 이 방식에는 여러 우회 노드 간의 경합을 방지하는 데 필요한 충돌 방지 기능도 포함되어 있습니다. 제안된 방식의 패킷 성공 확률은 Rayleigh 페이디드 단일 및 다중 홉 링크에 대한 이론적 분석과 시간 영역 컴퓨터 시뮬레이션을 통해 연구되었습니다. 수정된 QualNet 시뮬레이터를 사용한 네트워크 시뮬레이션은 최대 30Hz의 도플러 주파수에 대한 방식으로 패킷 성공 확률이 크게 향상되었음을 검증합니다.

Abstract: Multi-hop wireless ad hoc networks suffer from temporary link error due to fading. In order to improve packet transmission reliability and achieve efficient transmission in fading environment, a new cognitive temporary bypassing scheme is proposed based on a cross-layer approach and cognitive behavior of local nodes. The proposed scheme enables neighboring nodes to prepare and create a temporary bypass for lost-packets. This is done by monitoring message packets that include information of the multi-hop route and link-acknowledgement. The scheme also includes an anti-collision function that is necessary to prevent contention among multiple bypassing nodes. Packet success probability with the proposed scheme is studied both by theoretical analysis and time-domain computer simulation for Rayleigh faded single- and multi-hop links. Network simulation using a modified QualNet simulator validate that packet success probability is remarkably improved with the scheme for maximum Doppler frequencies up to 30 Hz.
