초록

본 논문에서는, ad-hoc on-demand distance vector (AODV) 라우팅 프로토콜의 브로드캐스트 스톰 문제가 발생하지 않는 이동 애드혹 네트워크를 위한 새로운 온디맨드 라우팅 프로토콜을 제안한다. 경로요청 패킷을 송신하는 노드와 목적지의 위치 정보를 이용하여, 경로요청 패킷을 전달할 수 있는 후보를 지리적으로 제한한다. 그 다음에, AODV의 원리를 따르는 라우팅 프로토콜들은 최초로 수신된 경로요청 패킷 이외의 중복 수신되는 경로요청 패킷을 모두 버리지만, 제안하는 라우팅 프로토콜은 중복 수신되는 경로요청 패킷을 해석하여, 경로요청 패킷의 불필요한 중복 재방송을 회피하고 송신한 경로요청 패킷에 대한 수동 ACK 기능을 수행한다. 제안하는 라우팅 프로토콜을 AODV의 소스 코드를 수정하여 QualNet으로 구현하고 시뮬레이션을 수행한 결과, 기존 AODV 대비, 노드 밀집도가 높고 트래픽이 많은 네트워크의 패킷 전달 비율 및 시간 지연을 크게 향상시킨다.

In this paper, we propose a novel geographical on-demand routing protocol for a mobile ad-hoc network (MANET) that resolves the broadcast storm problem of ad-hoc on-demand distance vector (AODV) routing protocol. The candidates relaying route request (RREQ) packet are geographically restricted by the locations of the destination and a (RREQ sender. Then, the duplicate RREQs, which are generally discarded in the protocols that follow the principle of the AODV, are parsed to avoid redundant RREQ rebroadcasts and to perform passive acknowledgement with respect to a RREQ rebroadcast. The proposed routing protocol is implemented by modifying the source code of the AODV in QualNet. It is shown through QualNet simulations that the proposed routing protocol significantly improves the packet delivery ratio and the latency of the AODV in high-density and heavy traffic network scenarios.
