차량간 통신환경에서 비안전 서비스를 위한 멀티홉 유니캐스트 라우팅 프로토콜에 관한 연구

Abstract

VANET routing protocols are designed to deliver data packets to their intended destinations using available vehicles as relays. Vehicular networks exhibit unique properties such as a possibly large number of vehicles, high dynamics, and fast-changing vehicle densities and partitions. Even if a large population of vehicles are present, constrained mobility, traffic lights, intersections and the liked lead to frequent network partitions and an uneven network density. The proposed GeoUnicast routing protocol use the realtime multi-hop forwarding for efficient and reliable transmission. GeoUnicast was evaluated in different highway traffic scenarios with both a realistic channel model and 802.11p model in our simulation.
