“…GyTAR -Greedy Traffic Aware Routing protocol (GyTAR) [18] is an overlaid approach similar to the approaches mentioned above in that packets are forwarded greedily toward the next junction which will then determine the best junction to forward next. GyTAR assumes that the number of cars is given per each road from roadside units and determines the connectivity of roads.…”

: Vehicular Ad hoc Network (VANET), a subclass of mobile ad hoc networks (MANETs), is a promising approach for the intelligent transportation system (ITS). The design of routing protocols in VANETs is important and necessary issue for support the smart ITS. The key difference of VANET and MANET is the special mobility pattern and rapidly changeable topology. It is not effectively applied the existing routing protocols of MANETs into VANETs VANET (Vehicular Ad-hoc Network) is a new technology which has taken enormous attention in the recent years. Due to rapid topology changing and frequent disconnection makes it difficult to design an efficient routing protocol for routing data among vehicles, called V2V or vehicle to vehicle communication and vehicle to road side infrastructure, called V2I. The existing routing protocols for VANET are not efficient to meet every traffic scenarios. Thus design of an efficient routing protocol has taken significant attention. So, it is very necessary to identify the pros and cons of routing protocols which can be used for further improvement or development of any new routing protocol. The easiest way to classify the geographic routing protocolsis by type of routing (Unicast, Broadcast or Geocast). Other way to classify them is by the use that the protocol gives to the position information (Packet forwarding, Route Selection, Cluster formation, Formation of cells, Classify Forwarding Group, or RouteRequest Forwarding). For this survey we will use the type of routing classification and in each protocol we'll talk about how the protocol uses the geographic information.

Vehicular Ad hoc Networks are special kind of Mobile Ad Hoc Networks. VANET is an emerging technology, which enables an extensive range of applications, including road safety, passenger convenience, self-driven vehicles, and intelligent transportation.Routing in Vehicular Ad hoc Networks is a challenging task due to the unique characteristics of the network. Unicast routing protocols in VANETs are the most fundamental protocols in ad hoc environment and they form the basis for constructing other types of protocols. Unicast routing protocols further classified into topology based, position based, cluster based and hybrid protocols.In this paper protocols belonging to unicast non-delay tolerant position based are discussed. We have implemented our comparison on the NS2 simulator. Simulation of NDT routing protocols A-STAR, CAR, and GyTAR are carried out and the results are presented.

“…However, more sophisticated approaches have been proposed by the research community, mainly differing in the weights that are assigned to each edge or, more formally, the metric space used to calculate the shortest path between source and destination. For example, the GyTAR proposal [12] also takes into account dynamic properties, such as the vehicular traffic density, in order to select route paths that increase the probability for an end-to-end multi-hop connectivity.…”

Abstract-Cooperative vehicular systems require the design of reliable and efficient multi-hop networking protocols to achieve their foreseen benefits. Although many geo-routing protocols have been proposed in the literature, few contributions have analysed the benefits that road side infrastructure units could provide to successfully route data from source to destination. In this context, this paper proposes a novel infrastructure-assisted routing approach designed to improve the end-to-end performance, range and operation of multi-hop vehicular communications by exploiting the reliable interconnection of infrastructure units. The conducted investigation shows that the proposed infrastructureassisted routing approach achieves its objectives, and reduces the routing overhead compared to other greedy position-based geo-routing protocols. Finally, the paper shows that to obtain the maximum benefits from the proposed infrastructure-assisted routing approach, optimal infrastructure deployment strategies must be further investigated.
