Abstract

Nodes communicate through wireless channels under peer-to-peer level in ad-hoc mobile networks. The nodes are free to move around in a geographical area and are loose]y bounded by the transmission range of the wireless channels. Also, a node is completely free to move around, there is no fixed final topology. Hence, to manage the inter-node communication and data exchange among them a leader node is required. In this paper we introduce an efficient leader election algorithm for mobile ad hoc networks where inter-node communication is allowed only among the neighboring nodes. Furthermore we present the result of performance evaluation through simulation. The algorithm is efficient and practical since it uses least amount of wireless resources and does not affect the movement of the nodes.

이동 에드 혹 네트워크(Mobile Ad hoc Network)에서는 노드들이 pear-to-pear 레벨에서 무선 채널을 통하여 대화 한다. 노드들은 지리적으로 이동이 자유로우며 무선 채널들은 영역 내에서 약하게 결합된다. 그리고 노드들이 자유롭게 이동할 수 있기 때문에 고정된 네트워크의 형태가 존재하지 않는다. 따라서 노드들간의 데이터 교관이나 노드간의 통신을 관리하기 위해서 리더 노드(Leader Node)가 필요하다. 본 논문에서는 이웃 노드간에만 대화가 허용되는 이동 에드 혹 네트워크를 위한 효율적인 리더 노드 선택 알고리즘을 소개한다. 그리고 시뮬레이션을 통한 알고리즘의 성능 평가 결과를 보인다. 본 논문에서 소개한 알고리즘은 노드들의 이동에 영향을 받지 않고 최소한의 무선 자원만을 사용하는 효율적이고 실용적인 알고리즘이다.
