The smart city applications attract attention more and more in today's world, and vehicular network is one of the big and important part of them. VANET provides many safety and infotainment applications with DSRC (Dedicated Short-Range Communications). Since VANET's structure is ad-hoc based, it lacks the standard infrastructure of the classical computer networks. Some of the applications in VANET requires multi-hop routing between distant nodes in network. However, reliable routing is a major problem in VANET, because of random distribution and high mobility of the nodes. This thesis intends to provide a reliable routing algorithm in urban areas for VANET. With the help of GPS devices and digital maps, the proposed algorithm uses the network nodes at road intersections to achieve a successful geo-routing. In order to verify effectiveness of the proposed algorithm, two simulation studies are conducted. While SUMO is used to simulate urban city environment and vehicle behavior, NS-3 is used to simulate the vehicular network. MAC and Physical Layers of the network are implemented as IEEE 802.11p standards. The Network and Transport Layers is implemented as ETSI ITS standards. Within this context, the first results show that a reliable routing can be achieved with a simple digital map and even cheap GPS devices. The second study indicates that the proposed algorithm has affectively more success than some well-known routing algorithms.
