.Vehicular ad hoc network (VANET) is a wireless emerging technology that aims to provide safety and communication services to drivers and passengers. In VANETs, vehicles communicate with other vehicles directly or through road side units (RSU) for sharing traffic information. The data dissemination in VANETs is a challenging issue as the vehicles have to share safety critical information in real time. The data distribution is usually done using broadcast method resulting in inefficient use of network resources. Therefore, to avoid the broadcast storm and efficiently use network resources, next forwarder vehicle (NFV) is selected to forward data to nearby vehicles. The NFV selection is based on certain parameters like direction, distance, and position of vehicles, which makes it a multicriteria decision problem. In this paper, analytical network process (ANP) is used as a multicriteria decision tool to select the optimal vehicle as NFV. The stability of alternatives (candidate vehicles for NFV selection) ranking is checked using sensitivity analysis for different scenarios. Mathematical formulation shows that ANP method is applicable for NFV selection in VANETs. Simulation results show that the proposed scheme outperforms other state-of-the-art data dissemination schemes in terms of reachability, latency, collisions, and number of transmitted and duplicate data packets.

This paper starts with an overview of vehicular ad hoc networks (VANETs) and their characteristics. Then this paper reviews diverse applications of VANETs and the requirements of these applications. In addition it reviews VANETs standards, different broadcasting presented in a variety of studies, and also associated issues with data dissemination in connected and fragmented vehicular networks to solve broadcast storm problem and temporary disconnected VANETs. The discussion will be about the encountered challenges and presented solutions with respect to the related issues, based on the literature and strength and weakness of each protocol.

Dynamic nature of vehicular ad hoc networks (VANETs) creates great challenges for message dissemination. To satisfy the high reliability and low delivery latency requirements for safety applications in VANETs, a dynamic epidemic broadcasting model is presented in this paper. On the basis of the ordinary differential equations, the proposed optimal control scheme is analyzed to understand the epidemic broadcasting properties, which include the message delivery probability, the expected delivery latency, and the number of copies. The correctness of the theoretical analyses is confirmed by simulations, and the experiment results prove the efficiency of the optimal epidemic broadcasting model. subclass of the WAVE technologies for vehicle-to-vehicle and vehicle-to-infrastructure interactions, which aims at accelerating the deployment of VANETs as well as improving traffic safety [2][3][4][5]. However, because the IEEE 1609 family provides only the overall protocol that is suitably used in VANETs, the actual model for information dissemination and the efficient algorithm to be implemented under this protocol are left to the designers.On the other hand, VANETs face great challenges including dynamic network topology, lack of centralized control, and unattended potential failures in wireless link [6]. High mobility of vehicles leads to more uncertainty of opportunistic transmission between two vehicles. Additionally, sparse node density and opportunistic inter-meeting between any two vehicles make absence of end-to-end paths from communication sources to their destinations in VANETs in most time [7]. VANETs are also characterized by intermittent connection in many traffic situations and process message propagation in the delay-tolerant manner as delay tolerant networks. So, many traditional routing protocols and message dissemination models are no longer suitable or fail to work for VANETs, and a novel-efficient broadcasting mechanism for message dissemination is necessary [8].In the past few years, a novel routing paradigm, so called 'the store-carry-and-forward', has been developed and studied at full length to support opportunistic communication in VANETs [9]. In this routing paradigm, a mobile node is able to store the message in its buffer with limited capacity after receiving that message and then carries the message as it moves unless the next hop for routing the message is available. This node will forward the stored message to other new mobile nodes when those nodes that it encounters move into its communication coverage. The process is named as 'communication contact' or 'inter-meeting' between two vehicles and can be analogous to the spread of infectious diseases [10]. Some improved variations of the epidemic-based routing have recently received a large amount of attentions in current research literatures [11][12][13][14][15]. For example, Ren et al. adopt an approach of adaptive compression of vectors to reduce some redundant overhead when nodes exchange summary vectors (SVs) and request vectors and store th...
