Abstract

Now a days, there are various application functions to transmit from vehicles to the Internet and vice versa. And the communication can be operated through a roadside infrastructure including with possible use of routing protocols. Specifically, autonomous vehicles for remote driving and monitoring requires transmitting of high depth of multimedia such as video. Especially in a populated urban area, an efficient network is vital because of handling a great amount of the data. Therefore, in this paper, efficient network topology for a crossroad in urban area is suggested by performance evaluation of vehicular networks using a wireless LAN and a routing protocol. For the performance evaluation, various vehicular network topologies are designed and simulated in OPNet simulator.

최근에 전기자동차의 상용화가 머지않은 상황에서 운전자를 위한 다양한 전자적 기능들이 개발되어지고 있다. 특히, 뇌파(EEG)를 통하여 운전자의 상태를 모니터링하면서 졸음방지나 건강상태를 실시간으로 점검하는 기능들이 있다. 자동차 운전자의 뇌파를 의료기관 서버에 전송하여 관련 기능들을 제공할 수 있는데 이때 자동차간 또는 자동차와 노변장치간의 원활한 통신기능이 필수적이다. 따라서 본 논문에서는 도심의 교차로환경에서 원활한 EEG 통신기능을 제공하는 라우팅 프로토콜을 제시하기 위해 AODV, DSR, GRP, OLSR, TORA와 같은 5가지의 라우팅 프로토콜로 운영되는 무선통신망을 각각 설계하고 이를 OPnet 네트워크 시뮬레이션을 통하여 성능을 평가하고 결과를 제시하고자 한다.
