초록
본 연구는 무선 멀티홉 네트워크를 위한 포텐셜 필드 기반 라우팅 기법을 기초로 하며, 특히 네트워크 환경의동적 변화에 대응할 수 있는 방법으로 네트워크 홀 문제를 해결하기 위해 기존에 제안된 가상노드 기법의 유효성을탐구한다. 이전 연구들은 가상노드 기법을 적용한 해당 라우팅 기법이 네트워크 홀 문제 상황에서 우수한 성능을 보였음을 확인했지만, 동적인 네트워크 상황을 고려한 시도는 없었다. 본 연구는 링크 손실이나 노드 고장과 같은 동적 네트워크 변화를 직접 고려하며 가상노드 기법을 적용한 포텐셜 필드 라우팅 기법의 적응성을 검증하고자 한다. 이를 위해NS-3 시뮬레이터를 활용하여 성능 평가를 수행하며, 기존 접근법들과 비교하여 해당기법의 동적 네트워크 변화 상황에대한 향상된 적응성을 입증한다. 본 연구는 실제 네트워크에서 발생할 수 있는 동적인 네트워크 상황 변화에 대응할수 있는 해법을 찾았다는 점과 그 해법으로 기존 가상노드 기법의 활용 범위를 확대하였다는 점에서 의의가 있다.
Abstract
This paper focuses on the potential field-based routing scheme developed for wireless multihop networks, emphasizing the exploration of the previously proposed virtual node concept to address network hole problems in dynamic network environments. Previous studies have demonstrated the superior performance of integrating the virtual node scheme into this routing strategy under network hole scenarios, but they have not addressed dynamic network conditions. This study directly considers dynamic network changes such as link failures or node breakdowns, validating the adaptability of the potential-field routing scheme integrated with the virtual node concept. Performance evaluations using the NS-3 simulator are conducted to demonstrate its improved adaptability to dynamic network change situations, compared to conventional approaches. This study highlights the significance of exploring new applications of the virtual node concept for effectively managing dynamic network changes in real-world scenarios.
