애드혹 네트워크에서 빠른 이동성을 위한 라우팅 프로토콜 설계

Abstract

There are several wireless communication methods for vehicle to vehicle communication and the communication methods using ad-hoc have been studied recently. But to use the ad-hoc communication method in vehicle to vehicle communication, there are so many problems which we have to solve. Especially fields of MAC and Routing Protocol have been actively researched for vehicle to vehicle communication. Among of them routing protocol is a role of discovery new routing path and routing path maintenance. If a vehicle to vehicle communication environment has high speed, the total network performance will be rapidly down. Because existing routing protocol has developed in environment of high speed so many part is modified or improved. In this paper HRP routing protocol that prior to existing routing protocol is designed. We use the Cross-Layer type and GPS informations for routing overload lower than existing protocol. Result in analysis Packet delivery fraction is improved 5 ∼ 15%, and Routing load is lower 10% ∼ 50% than other protocols MAC load is improved 5% ∼ 60% , End to end delay time is even lower. Consequently we confirmed that HRP is still more than the existing routing protocols.
