Many broadcast protocols have been proposed in Vehicular ad-hoc Network (VANET) for safety applications and traffic efficiency. GeoBroadcast, which the sender sends information to the geographical area, has been standardized by the ETSI Technical Committee ITS. The routing protocol is a key technology satisfying communication requests of high reliability, low delay and universality for GeoBroadcast. However, there are few implementation and field test of routing protocol. This paper proposes a Received Signal Strength Indicator (RSSI) based Omni-Directional Routing (ROR) Algorithm. This protocol based on the combination of two protocols: the Greedy Forwarding (GF) that is a sender-based protocol, and the Contention-Based Forwarding (CBF) that is a receiver-based protocol. Furthermore, ROR takes RSSI, driving direction and dynamic scene into account. Meanwhile we conduct extensive field tests with more than twenty vehicles to evaluate the performance of vehicle communication in terms of Packet Loss Rate (PLR), Node Coverage Ratio (NCR) and Average End-to-End Delay (E2ED). By comparing the performance of CBF and Advanced Forwarding protocol with the ROR, ROR in real vehicle's environment has higher NCR and lower E2ED, in particular when the topology of the vehicles changes frequently in the target area.
