摘要：A Vehicular Ad Hoc Network (VANET) is a network formed purely among vehicles without presence of any communication infrastructure as base stations and/or access point. Frequent topological changes due to high mobility is one of the main issues in VANETs. In this paper we evaluate Ad-hoc On-Demand Distance Vector (AODV) and Optimized Link State Routing (OLSR) routing protocols using 802.11a and 802.11p in a realistic urban scenario. For this comparison, we chose five performance metrics: Path Availability, End-to-End Delay, Number of Created Paths, Path Length and Path Duration. Simulation results show, that for most of the metrics evaluated, OLSR outperforms AODV when 802.11p and that 802.11p is more efficient in urban VANETs
