Abstract

In this paper, we propose an Entropy-based Cooperative-Aided Routing Protocol (ECARP) in Mobile Ad-hoc fireless Sensor Networks (MAWSN). The main contributions and features of this paper are as follows. First, the entropy-based cooperative routing protocol which is based on node mobility is proposed for supporting stable routing route construction. Second, cooperative data transmission method is used for improving data transmission ratio with the improved SNR. Third, we consider a realistic approach, in the points of view of the MAWSN, based on mobile sensor nodes as well as fixed sensor nodes in sensor fields while the conventional research for sensor networks focus on mainly fixed sensor nodes. The performance evaluation of the proposed routing protocol is performed via simulation and analysis.

본 논문에서는 모바일 ad-hoc 무선 센서 네트워크에서 엔트로피기반 협력도움 라우팅 프로토콜을 제안한다. 제안된 라우팅 프로토콜의 주요한 특징 및 기여도는 다음과 같다. 첫째, 노드들의 이동성 관점에서 안정된 경로의 설정을 위해서 엔트로피 기반의 라우팅 경로 설정 방법을 제안 사용한다. 둘째, 향상된 SNR을 가지고 데이터 전달 효율을 효과적으로 증가시키기 위해서 협력도움 데이터 전송 방법을 사용한다. 셋째, 기존의 연구가 주로 고정된 센서 노드들로 구성된 센서필드에서 이루어진 반면에, 본 논문에서는 센서필드에서 고정된 센서 노드들 뿐만 아니라 이동 노드들도 함께 고려한 모바일 Ad-hoc 무선 센서 네트워크(MAWSN) 관점에서 연구가 진행된다. 제안된 라우팅 프로토콜의 성능평가는 시뮬레이션과 이론적인 분석을 통하여 이루어진다.
