The routing paths of vehicular ad-hoc network (VANET) in a city environment consists of many possible paths and junctions. Shortest path routing is not viable because each path has to be populated with vehicles. A scalable multi-hop routing protocol which adapts well to the city environment even with rapidly changing network topologies and lots of disconnected, sparse and dense network conditions is sought after. Here, we propose a new position-based routing protocol i.e. JARR, which will address the shortcomings of the current protocols by estimating the density of paths to be used. Packets are also routed from one junction to another and the direction and position of next hops are pre-considered with different ratios depending on the estimated density of the path. Simulation works were performed to compare JARR routing protocol with an existing protocol which uses the shortest path strategy.
