ABSTRACT Vehicular Delay-Tolerant Networking (VDTN) is an extension of the Delay-Tolerant Network (DTN) architecture concept to transit networks. VDTN architecture handles non-real time applications, exploiting vehicles to enable connectivity under unreliable scenarios with unstable links and where an end-to-end path may not exist. Intuitively, the use of stationary store-and-forward devices (relay nodes) located at crossroads where vehicles meet them and should improve the message delivery probability. In this paper, we analyze the influence of the number of relay nodes, in urban scenarios with different numbers of vehicles. It was shown that relay nodes significantly improve the message delivery probability on studied DTN routing protocols.

    ABSTRACT: Recently, the Delay Tolerant Networks (DTN) have been utilized in various operational communication paradigms. This includes the communication scenarios that are subject to disruption and disconnection as well as the scenarios with high delay and frequent partitioning, i.e., Vehicular Ad hoc Networks (VANETs). Due to the several characteristics match, new research paradigm named as Vehicular Delay Tolerant Networks (VDTNs) is introduced. Through relays and store- carry-forward mechanisms, messages in VDTNs can be delivered to the destination without an end-to-end connection for delay- tolerant applications. However, the choice of routing algorithms in VDTNs is still under study. The main objective of routing protocols in VDTNs is to maximize the probability of delivery at the destination while minimizing the end-to-end delay. Until now, many routing protocols have been proposed to meet requirements of varying applications. In this paper, we therefore provide a detailed study of recently proposed routing schemes for VDTNs. We also perform comparative analysis on the basis of unique criterion such as forwarding metrics with their implementations and so on. In addition, open challenges and future directions are provided to make room of interest for the research community.

    ABSTRACT: Most of the nodes in a vehicular ad hoc network (VANET) move continuously, and thus the link quality changes constantly. As a result, the connections are intermittent and many network services (e.g., video conferencing) fail to function properly. Although many routing algorithms for discovering available transmission paths have been proposed, it is almost impossible to find a reliable end-to-end path in VANET environments since transmission failures occur so frequently. As a result, developing efficient retransmission schemes is of great practical importance. Accordingly, the present study proposes an application layer forwarding protocol designated as Intelligent Adjustment Forwarding (IAF), in which a segment-to-segment transmission paradigm is used to enhance the data delivery performance. The simulation results show that IAF not only improves the reliability of the data transmissions, but also enables a more efficient recovery in the event of transmission failures. Significantly, the improved transmission performance of IAF is accomplished with no more than a slight increase in the transmission time relative to that of existing VANET approaches.

    ABSTRACT: Vehicular communications refer to a wide range of networks adopted in environments characterized by sparse connectivity, frequent network partitioning, intermittent connectivity, long propagation delays, asymmetric data rates, and high error rates. These environments may also be characterized by a potential non-existence of an end-to-end path. Cooperation among network nodes is crucial to address these challenging connectivity issues. In order to contribute for a better network performance, network nodes should to share their storage, bandwidth, and energy resources with each other. By sharing their resources each node contributes to store, carry, and forward network data in order to mutually enhance the overall network performance. However, not all network nodes are able to cooperate and sometimes they may have an uncooperative behavior in order to save their own resources. Such behavior severely affects the network functionality and performance. Then, this survey overviews the most recent advances related to cooperation on vehicular communications. The goal of this work is not only to present how cooperation between network nodes has advanced, but also to show the benefits and drawbacks of cooperation, and to identify open issues providing guidelines for further contributions in this type of networks.
