“…The reactive protocols are usually based on distance vector routing. The most well-known examples of reactive routing protocols in MANETs are AODV, DSR, and TORA [7]. For instance, the DSR protocol is useful for unicast traffic with multiple routes between source and destination, but it suffers from the growing packet size.…”

“…Unlike previously described topology-based routing protocols, the geographical protocols derive their routing strategy from knowledge of geographical locations of other nodes in the network [7][8][9][10][11][12]. The geographical locations can be also used to forecast the propagation conditions either by simple mathematical models if it needs to be performed in real time or by simulations if the off-line channel modeling is acceptable.…”

The interest in mobile ad-hoc networks (MANETs) and often more precisely vehicular ad-hoc networks (VANETs) is steadily growing with many new applications, and even anticipated support in the emerging 5G networks. Particularly in outdoor scenarios, there are different mechanisms to make the mobile nodes aware of their geographical location at all times. The location information can be utilized at different layers of the protocol stack to enhance communication services in the network. Specifically, geographical routing can facilitate route management with smaller overhead than the traditional proactive and reactive routing protocols. In order to achieve similar advantages for radio resource management (RRM) and multiple access protocols, the concept of virtual cells is devised to exploit fully distributed knowledge of node locations. The virtual cells define clusters of MANET nodes assuming a predefined set of geographically distributed anchor points. It enables fast response of the network to changes in the nodes spatial configuration. More importantly, the notion of geographical location can be generalized to other shared contexts which can be learned or otherwise acquired by the network nodes. The strategy of enhancing communication services by shared contexts is likely to be one of the key features in the beyond-5G networks.

Geographical Routing is a routing methodology mainly used for wireless mobile networks (Mobile Adhoc Networks, MANETs). MANETs are comprised of mobile nodes or mobile computing devices which are free to move randomly and thus the network's wireless topology may also change randomly. In Geographical Routing, nodes need to maintain the current positions of their neighbors for making forwarding decisions and hence the Adaptive Position Update (APU) method is proposed. Based on the flexibility of the nodes and the forwarding decisions made in the network, APU dynamically keeps in track of the rate of position updates. It is based on nodes with movements which are complex to predict their updated positions frequently and also the nodes which are closer to forwarding paths and update their positions more frequently. The APU is validated by network simulations showing that APU can potentially reduce the traffic load and acknowledge the mobility of nodes. It also improves the routing performance in terms of packet delivery ratio and packet delays.

“…Broadcast routing is message-passing in the form of flooding, where each node forwards the received message to other nodes. This method can guarantee the target to receive information quickly and accurately, but it will cause great load [14].…”

Vehicular Ad-hoc Network (VANET) is an emerging autonomous dynamic topology network. It is a special kind of Mobile Ad-hoc Network in which the vehicles exchange their information with each other. VANET turns every car in it into a mobile node and use these nodes to create a mobile dynamic network. The purpose of VANET is to supply a wireless connectivity and deploy various applications such as collision avoidance, safety and improving the traffic efficiency as provisioned by the Intelligent Transportation System (ITS). The vehicles are constrained by the realistic traffic environment, and now the simulations are mainly network simulations which cannot simulate the real trace of the vehicle. But as nodes in VANETS have very high mobility, so there are lots of challenges to route the packets to there final destination which need to be addressed by existing/proposing new solutions for the same. Keeping view of above, In this paper, We summarize the existing VANET routing protocols and classify and compare them. Then, We list several classic routing algorithms and analyze their characteristics and advantages and disadvantages. Finally, by analyzing the status quo of vehicle-mounted routing protocols, we illustrate the difficulties and challenges that vehicle-mounted routing protocols will encounter in the future.
