Abstract

Recently, in the U-health area, there are research related on monitoring brainwaves in real-time for coping with emergent situations like the fatigue driving, cerebral infarction or the heart attack of not only the patients but also the normal elderly folks by transmitting of the EEG(Electroencephalograph). This system could be applied to hospitals or sanatoriums. In this paper, it is applied for the vehicular ad-hoc network to prevent the car accident in advance by monitoring the brainwaves of a driver in real-time. In order to do this, I used mobile ad-hoc nodes supported in the Opnet simulator for the efficient EEG brainwave transmission in the VANET environment. The vehicular ad-hoc networks transmitting the brainwaves to the nearest road-side unit are designed and simulated to draw an efficient and proper vehicular ad-hoc network environment.

최근 U-health 분야에서는 EEG(Electroencephalograph) 뇌파를 전송하여 환자뿐만 아니라 일반 노약자를 대상으로 졸음운전이나 뇌졸중, 또는 심장마비와 같은 위기상황에 대처하기 위해 실시간으로 뇌파를 모니터링하는 시스템을 연구하고 있다. 이러한 시스템은 병원이나 요양원등 다양한 지역에 적용할 수 있다. 본 논문에서는 자동차 통신망에 적용하여 운전자의 뇌파를 실시간으로 모니터링하고 미연에 사고를 방지할 수 있는 통신망 시스템의 성능을 평가하고자 한다. 이를 위해 VANET환경에서 EEG뇌파 전송을 효율적으로 할 수 있도록 옵넷 시뮬레이터에서 제공하는 모바일 애드혹 노드를 사용하였다. 운전자의 뇌파를 노변기지국으로 전송하는 애드혹한 자동차 통신망을 설계하고 시뮬레이션을 통하여 도심 지역에 적합한 환경을 도출하였다.
