This research propose a new routing protocol that is based on the hop-count and node-degree metrics to determine route strength. The hop-count is derived by identifying the next-hop node that has the minimum distance to the sink node. Meanwhile, the node-degree is obtained through the vehicle ID of each neighbouring nodes in its radius. All the nodes or vehicles in VANETs context were assumed to be equipped with an OnBoard Unit (OBU) that will periodically send beacon messages to other nodes around the transmission range area. From the simulation results, it is found that the HDbR protocol is suitable to be used in Vehicular Ad-hoc Networks (VANETs) as it produces high network throughput and minimum end-to-end delay. Thus it is comparable to existing protocol such as AODV when it was evaluated in various speeds scenario.
