Abstract

Spurred by the advent of ITS and WAVE (Wireless access in vehicular environments) as well as the wide-spread use of smart phones, WMN technology is considered to be a promising technology for extending the Internet access coverage supported by the IEEE802.11 based access points. In this paper, we propose a new MAC protocol which can efficiently utilize the multi-interface multi-channel communication capabilities supposedly equipped in most mesh routers, thereby increasing the network throughput considerably. We also verified its performance through computer simulations.

ITS와 WAVE 등의 도입 및 스마트 폰의 광범위한 보급에 따라 WMN 기술은 IEEE802.11 기반의 AP의 무선접속 범위를 확장시키기 위한 효율적인 기술로서 인정받고 있다. 본 논문에서는 WMN 구현에 있어서 대부분의 메쉬 라우터가 갖고 있는 다중 인터페이스/다중 채널 기능을 활용하여 전반적인 통신 속도 및 처리율 향상을 위한 MAC 프로토콜을 제안하고 컴퓨터 시뮬레이션을 통하여 성능을 검증하였다.
