Vehicular Ad-hoc Network (VANET) is an emerging solution introduced to enhance active safety and to disseminate infotainment messages in the dynamically changing vehicular network. Communication between vehicular nodes in VANET enables information exchange about road hazards and traffic situation with the capability of extending sensing range via relaying and broadcasting the data packet. But Vehicle-to-Vehicle (V2V) communication requires fast, reliable and lossless data transmission for a large set of services. In this study, the navigation map data and routing information is used to forward the data packet towards its destination. Mainly, routing decision is made at the intersection zones. In order to assure fast and lossless packet delivery performance, distance on the road map and wireless access measurements are used to calculate the cost. Finally, the presented local routing algorithm routes the data packet towards a vehicular node in a neighbor intersection zone to relay the data packet towards its destination. Simulation scenario of an urban area is implemented in the vehicular network simulator (ns-3) and mobility (SUMO) simulator platforms. As a proof-of-concept, the effectiveness of using local routing algorithm taking into account the wireless access measurements is demonstrated.
