Abstract

In this paper, we propose a location based multicast routing protocol, called Geomulticast, in mobile ad-hoc wireless networks. The main features and contributions of the proposed geomulticast are as follows. First, support data transmission to only the specific mobile nodes within a target area. Second, establish stable routing route by using mobility information of nodes. Third, reduce control overhead, power for construction of routing route by using geomulticast guided line information. Fourth, present a theoretical model for establishing stable route. The performance evaluation of the proposed geomulticast is executed by using OPNET simulation and theoretical analysis, and the results of simulation and theoretical analysis have similar patterns. And we can see that data packets are efficiently transmitted to specific user groups within a specific area.

본 논문에서는 모바일 Ad-hoc 무선 네트워크에서 경로 안정성을 이용한 위치기반 멀티캐스트 라우팅 프로토콜(지오멀티캐스트)을 제안한다. 본 논문에서 제안한 지오멀티캐스트의 주요한 특징 및 기여도는 다음과 같다. 첫째, 어떤 특정한 지역 내에 분포하는 모바일 노드들 중 특정 노드들에게 데이터 전송이 가능하다. 둘째, 노드들의 이동성 정보를 이용하여 안정적인 라우팅 경로를 선택한다. 셋째, 지오멀티캐스트 가이드라인 정보를 사용하여 경로 설정을 위한 불필요한 컨트롤 오버헤드나 전력의 낭비를 줄일 수 있다. 넷째, 지오멀티캐스트 서비스를 지원하기 위한 안정된 경로 설정 관련 이론적인 모델을 전개한다. 제안된 지오멀티캐스의 성능평가는 OPNET을 이용한 시뮬레이션과 이론적인 분석을 통하여 이루어졌으며, 이론적인 결과와 시뮬레이션 결과가 유사하게 일치함을 확인 하였다. 그리고 특정한 영역에 있는 특정한 그룹에 속해있는 노드들에게 효과적으로 데이터 페킷 전송이 이루어짐을 알 수 있다.
