초록

군집지능은 단순한 객체들이 팀을 이루어 간단, 단순한 행동을 조합하여 복잡하고 의미 있는 과제를 수행하는 것을 말한다. 네트워크 라우팅 분야에서도 이러한 군집지능을 이용한 연구가 수행되어 왔다. 특히 동적 토폴로지에서 지역적 정보를 이용한 경로 설정이 필요한 이동 애드혹 네트워크 (mobile ad-hoc network: MANET)에서의 라우팅은 군집지능의 한 응용분야로 알려져 있다. 본 논문에서는 MANET에서 개미의 군집지능을 이용한 라우팅 방안을 제안한다. 제안 방안은 효율적인 개미 관리를 통하여 오버헤드를 줄이고, 경로 설정시간을 단축하는 것을 목표로 설정하였다. 모의실험 결과, 제안 방안은 패킷 전송율의 성능은 유지하면서 경로 설정시간, 종단간 지연, 오버헤드에서는 향상된 성능을 보여주었다.

Swam intelligence refers that a large group of simple and unsophisticated entities work together to achieve complex and significant tasks. Researches using such swarm intelligence has been performed in the network routing area. Expecially, it has been well known that routing in mobile ad-hoc networks whose features are dynamic topology and routing based on the local information is one of the applications of swarm intelligence. In this paper, we propose an ant-based routing method for MANET. The proposed method sets its goals to reduce overheads by managing ants efficiently, and to reduce route set up time. The results obtained from simulations proved that the proposed method provides shorter path set-up time and end-to-end delay and less overhead while providing comparable packet delivery ratio.
