초록

스마트 기기의 발달과 더불어 무선 센서 네트워크의 대용량 데이터를 효율적으로 전송하기 위한 최적의 채널 선택이 매우 중요한 요인이 된다. 이러한 센서 노드가 사용할 채널이 고정된다면 주파수 부족의 발생과 다양한 환경에서 센서 노드들을 지원하는데 제약이 야기될 수 있다. 본 논문에서는 채널 설정 링크들의 간섭으로 인한 성능 저하를 줄이고 네트워크의 사용 가능한 채널을 찾기 위한 효율적인 채널 검색 방법을 제안하고자 한다. 컴퓨터 모의실험 결과, 제안한 알고리즘은 간섭 링크 수가 증가할수록 효율적인 채널을 설정할 수 있고 간섭으로 인한 비컨 패킷 수신 대기 시간을 줄일 수 있음을 보여준다.

It is important to select the most appropriate channel for efficient transmission of massive multimedia data between smart devices in wireless sensor network. In the fixed channel method, sensor nodes can restrict usefulness of frequency and may be a major constraint to support frequency at various environments. In this paper, we propose a modified efficient channel search algorithm that determines available channel and tolerance of interference of links between two nodes. From the results of computer simulation, the proposed method shows that the link of channel can be set efficiently than the other methods even if the number of interference links increases and the beacon packet waiting time caused by interference is reduced remarkably.
