초록

본 논문에서는 레일리페이딩 환경의 모바일 Ad-hoc 무선 센서네트워크에서 네트워크 컨버젼스 및 전송 효율 서비스를 효과적으로 지원하기 위한 협력 라우팅 프로토콜 (CooRP)을 제안한다. 제안된 CooRP의 주요한 특징 및 기여도는 다음과 같다. 첫째, 라우팅 경로들은 방향성 안내 라인 영역 내에서 노드들의 이동성 정보를 이용한 엔트로피 개념 기반 위에서 설정되며, 경로 설정을 위한 컨트롤 오버헤드를 줄일 수 있다. 둘째, 페킷 전송 효율을 증가시키기 위해서 설정된 라우팅 경로에 기반을 둔 향상된 SNR을 지원할 수 있는 협력 데이터 전송 전략이 사용된다. 셋째, 제안된 CooRP의 협력전송에 대한 이론적인 분석이 outage probability를 가지고 이루어진다. 제안된 CooRP의 성능평가는 OPNET을 사용한 시뮬레이션과 이론적 분석을 통하여 이루어진다. 성능평가를 통하여 제안된 프로토콜은 안정된 경로 설정 및 협력 전송을 통한 데이터 전송효율을 효과적으로 증가 시킬 수 있음을 알 수 있다.

In this paper, In this paper, we propose a Cooperative Routing Protocol (CooRP) for supporting network convergence and transmission services efficiently in mobile ad-hoc wireless sensor networks with Rayleigh fading environments. The main contributions and features of this paper are as follows. First, the routing routes are decided on route stability based on entropy concepts using mobility of nodes within the direction guided line region to increase the operational lifetime of routes as well as reduce control overhead for route construction. Second, a cooperative data transmission strategy based on the constructed stable routing route is used to increase packet delivery ratio with advanced SNR. Third, a theoretical analysis for cooperative data transmission of the proposed CooRP with outage probability is presented. The performance evaluation of the proposed CooRP is performed via simulation using OPNET and analysis. The results of performance evaluation show that the proposed CooRP by using stable routing routes and cooperative transmission can increase packet delivery ratio efficiently.
