Recently, vehicular ad hoc networks (VANETs) have received more attention in both academic and industry settings. One of the challenging issues in this domain is routing protocols. VANETs' unique characteristics such as high mobility with the constraint of road topology, fast network topology changes, frequently disconnected networks, and time-sensitive data exchange makes it difficult to design an efficient routing protocol for routing data in vehicle-to-vehicle (V2V) and vehicle-toinfrastructure communications. Designing routing protocols for V2V commutations are more challenging due to the absence of infrastructure nodes in the communication procedure. They become even more challenging, when they get benefit from dynamic anchor computation method in which the anchor nodes (junctions or basic nodes for routing) are dynamic in their routing procedure. Positionbased routing protocols have been proven to be superior and outperform the other protocols since there is no requirement to establish and save a route between source and destination during the routing process which is suitable for dynamic nature of vehicular networks. In this paper, the performance of V2V dynamic anchor position-based routing protocols, which are proposed for the most challenging condition of packet routing in VANET, are investigated and evaluated under two different scenarios (i.e. various vehicle densities and velocities) through NS-2. The obtained results are then illustrated based on average delay, packet delivery ratio and routing overhead as routing performance indicators. Our objective is to provide a quantitative assessment of the applicability of these protocols in different vehicular scenarios. The comparison provided in this paper makes the research contribution of this survey paper quite higher than a regular survey paper only with explanations.Keywords Vehicular ad hoc networks Á Position-based routing Á Anchor-based Á Vehicle-to-vehicle

Vehicular ad hoc network (VANET) is an emerging wireless communications technology that is capable of enhancing driving safety and velocity by exchanging real-time transportation information. In VANETs, the carry-and-forward strategy has been adopted to overcome uneven distribution of vehicles. If the next vehicle located is in transmission range, then the vehicle forwards the packets; if not, then it carries the packets until meeting. The carry mostly occurs on sparsely populated road segments, with long carry distances having long end-to-end packet delays. Similarly, the dense condition could have long delays, due to queuing delays. The proposed intersection-based routing protocol finds a minimum delay routing path in various vehicle densities. Moreover, vehicles reroute each packet according to real-time road conditions in each intersection, and the packet routing at the intersections is dependent on the moving direction of the next vehicle. Finally, the simulation results show that the proposed Intersection-Based Routing (IBR) protocol has less end-to-end delay compared to vehicle-assisted data delivery (VADD) and greedy traffic aware routing protocol (GyTAR) protcols.

“…Generally, the carry and forward strategy suffers an uncontrolled end-toend delay. The last one is infrastructure-based [22] scheme in which the infrastructure caches data and waits for a chance to forward. The drawback of this method is the lack of flexibility.…”

With the fast development of vehicular ad hoc networks (VANETs), various VANET applications, especially safety and infotainment service, have stronger requirements for reliable network connectivity. Intermittent connectivity has become a thorny problem in VANETs, which causes unreliable vehicle to vehicle (V2V) connection due to high vehicle mobility. In this paper, we have studied the network connectivity using a stochastic analysis model and then we prove average intervehicle distance influences VANET connectivity greatly. Based on our analysis, we propose a connectivity-sensed routing protocol (CSR) for VANETs in urban scenario. CSR utilizes vehicle distribution information collected by intersection infrastructure to help vehicles select a road not only with progress to destination but also with better network connectivity. Moreover, simulation results demonstrate that the CSR protocol achieves much lower end-to-end delay, higher delivery rate, and higher throughput than traditional routing protocols.
