--VANETs are special kind of Mobile Ad Hoc Networks (MANETs) that are formed between moving vehicles on an as-needed basis. Routing in VANET uses a greedy routing protocol which requires geographical information like location of any vehicle. The primary objective of this paper is to reduce the transmission delay by using some Road Side Units (RSU) already deployed along the roads. RSU gather information about all the vehicles which are connected in its range. Here each and every vehicle need not be communicated but the vehicles that are nearest and which have the information about location of destination are only involved. We use enhanced RLS which is hybrid communication from source to destination. It results to reduce the flooding requests and make communication faster which leads to improve the packet delivery ratio and reduce the transmission delay or end to end delay. In addition to this the source vehicle sends a request with its velocity to RSU, it will communicate with other RSU's for the destination vehicle. After finding the destination it will send the request with velocity of the destination. Based on the velocity of destination and intermediate nodes the source will increase its velocity to avoid the frequent link breakage in order to reduce the transmission delay. The proposed algorithm is simulated using NS2 and results shows that ERLS decreases the transmission delay and increases the packet delivery ratio. Keywords -VANET, Location-based Services, Geographic Routing, Hybrid Architecture.I. Introduction. VANET belongs to wireless communication network in which communication between vehicles takes place. The vehicles act as nodes in the network which form a network without any additional infrastructure. With rapid growing number of vehicles, saturation of the transportation infrastructure, and traffic congestion, accidents and transportation delays become unavoidable. Several mechanisms are implemented to improve the transportation systems as well as developed better and efficient routing mechanisms. VANETS have many applications in Road Safety, Passenger convenience etc. VANET communication has recently become an increasingly popular research topic in the area of wireless networking. A VANET turns every participating vehicle into a wireless router or node allowing vehicles to connect and create a network. Routing in VANET's is still a challenging issue due to its characteristics like high mobility of nodes, frequent disconnections, highly partitioning network. When the vehicle density is low, VANETs have a higher probability of getting disconnected frequently. VANET will become world's largest ad-hoc network, communication between vehicles to vehicle is in different types as Vehicle to Vehicle (V2V) -Vehicle to Vehicle communication is suitable for short range vehicular network. It provides real time safety, fast and reliable. It does not need any roadside infrastructure. It is not very useful in case of sparsely connected network or low density vehicular network. In V2V warning messages...

“…An autonomous vehicle is limited in perception, calculation, and decision-making processes from multiple interactive robot system addressed to overcome safety internallyAmessages can be forward based on the highest pheromone intensity from source to destination. Some example of the trajectory-based routing algorithm in unicast communication protocol are Greedy Perimeter Stateless Routing (GPSR) [13] [38], ACO-based Routing [39] [40], and PSO-Based Routing [41][42] [43] II.…”

Vehicle to Vehicle (V2V) communication is a specific type of communication on Vehicular Ad Hoc Network (VANET) that attracts the great interest of researchers, industries, and government attention in due to its essential application to improve safety driving purposes for the next generation of vehicles. Our paper is a systematic study of V2V communication in VANET that cover the particular research issue, and trends from the recent works of literature. We begin the article with a brief V2V communication concept and the V2V application to safety purposes and non-safety purposes; then, we analyze several problems of V2V communication for VANET related to safety issues and non-safety issues. Next, we provide the trends of the V2V communication application for VANET. Finally, provide SWOT analysis as a discussion to identify opportunities and challenges of V2V communication for VANET in the future. The paper does not include a technical explanation. Still, the article describes the general perspective of VANET to the reader, especially for the beginner reader, who intends to learn about the topic.
