Abstract
Vehicular Ad hoc Networks (VANETs) using wireless multi-hop technology have recently received considerable attention. Because of frequent link disconnection caused by high mobility and signal attenuation due to obstacles (e.g. tall buildings) in urban areas, it becomes quite challenging to disseminate packets to destinations locating in a specified area. We proposed a novel geocast routing protocol called GRUV for urban VANETs. GRUV adapts to the current network environment by dynamically switching three forwarding approaches which are used to compute forwarding zones. According to the locations, vehicles are categorized into crossroads nodes and in-road nodes, and different next-hop node selection algorithms are proposed respectively. Simulations with relatively realistic vehicle movement model and probability-based obstacle model show that GRUV has a higher performance compared with other geocast routing protocol.
