Abstract

The routing protocols designed for wired networks can hardly be used for mobile ad-hoc networks due to limited bandwidth of wireless transmission and unpredictable topological change. Recently, several routing protocols for mobile ad-hoc networks have been Proposed. However, when theme protocols are applied to support real time services like multimedia transmission, they still have problems in ad-hoc networks, where the topology changes drastically. In this paper, we propose a new route selection algorithm which selects the most reliable route that is impervious to route failures by topological changes by mobile hoots. For reliable route selection, the concept of virtual zone (stable zone and caution zone) is proposed. The zone is located in a mobile node'transmission range and determined by mobile node's mobility information received by Global Positioning System (GPS). The proposed algorithm is applied to the route discovery procedure of the existing on-demand routing protocol, AODV, and evaluated by simulation in various traffic conditions and mobility patterns.

유선 네트워크 환경을 위해 설계된 경로 설정 프로토콜들은 대역폭의 제한성과 예측할 수 없는 위상의 변화로 인해 이동 애드혹 (ad-hoc) 네트워크 환경에 적용하기에는 부적합하다. 최근 들어 애드혹 네트워크 환경에 적합한 경로 설정 프로토콜들이 많이 개발되었다. 그러나 위상이 급격히 변화하는 애드혹 네트워크에서 멀티미디어 데이타 전송과 같이 실시간 서비스를 지원하기에는 이러한 애드혹 경로 설정 프로토콜로는 한계가 있다. 본 논문에서는 애드혹 네트워크에서의 위상 변화에 대한 적응력을 향상시키기 위해서 위성 위치 확인 시스템 (GPS: Global Positioning System)을 활용한 가상 지역 (안정 지역, 경고 지역) 개념을 제안하고 있고 AODV의 경로 설립 과정 시 이러한 가상 지역 개념을 도입함으로써 이동 단말의 이동성에 의한 위상의 변화에도 잘 적응할 수 있는 안정된 경로의 설립을 목표로 하고 있다. 본 논문에서는 시뮬레이션을 통하여 다양한 트래픽 상태와 단말들의 이동성 형태에 따른 중요 변수들을 설명하였으며 이에 따라 제안하는 경로 설정 프로토콜들의 효율성을 검증하고 있다.
