초록

본 논문은 무선센서 망에서 소스 노드와 모바일 싱크 노드 간 데이터 전송경로를 효율적으로 관리하는 방법을 제안한다. 제안하는 방법은 최단거리 전송경로를 보장하며, 기존에 형성되었던 경로를 최대한 이용함으로써 경로재설정을 위한 비용을 줄일 수 있다. 실험 결과는 제안하는 방법이 기존 대표적 경로재설정 방법인 CODE와 EADA에 비해 경로 재설정 비용을 약 60% 감소시켰음을 보여준다.

This paper proposes an efficient path maintaining scheme in the grid based wireless sensor networks. The proposed scheme provides the shortest path from a source node to a mobile sink node in a re-established dissemination path. The shortest path can save energy consumption to deliver data to the destination. The proposed scheme can also reduce the cost for path maintenance by reusing the existing path. The simulation results show that the proposed scheme reduces the path maintenance cost by 60% compared to the conventional schemes.
