Ad hoc 환경에서 사용되는 On-demand 방식인 AODV 라우팅 프로토콜은 경로를 찾기 위하여 노드들이 가지고 있는 라우팅 테이블을 우선 검사하고, 만약 적합한 경로가 존재하지 않거나 유효하지 않은 경로, 또는 중간노드에서 경로손실이 발생하였을 경우 Route Discovery Process(RDP)를 수행하여 새로운 경로를 찾게 된다. 하지만 중 / 대형 Ad hoc 환경에서 이러한 RDP의 증가는 네트워크 성능의 저하를 초래한다. 본 논문에서는 경로설정을 위해 사용되는 AODV 라우팅 프로토콜에 Zone 개념을 도입한 AOZDV(Ad hoc On-demand Zone and Distance-Vector Routing Protocol)를 제안한다. AOZDV는 노드의 트래픽과 전력정보를 활용하여 소스 / 목적지 노드에 Zone을 형성하고, Zone 내부에서의 라우팅은 Destination-Vector Table을 활용하는 기법으로서, 시뮬레이션을 통해 AOZDV 가 기존의 라우팅 프로토콜들에 비해 노드들의 이동성으로 인해 발생하는 경로손실 및 RDP 가 감소함을 확인할 수 있었다.

Abstract

In Mobile ad hoc networks, AODV is one of the famous on-demand routing protocol, which use the routing tables in the nodes if possible, or Route Discovery Process (RDP) is triggered to find a new route. However increasing the traffic of RDP causes dropping of the network performance in the large size of ad hoc networks. In this paper, we propose a novel routing protocol, named as AOZDV (Ad hoc On-demand Zone and Distance-Vector Routing), which enhances the AODV protocol with zone routing. AOZDV creates a Zone with neighbor nodes of the source/destination using traffic and power information, and utilizes Destination-Vector Table for internal routing in the Zone. We show by simulations that AOZDV can reduce the occurrence rate of route fail and RDP caused by route fail compared to existing routing protocols such as DSR and AODV.
