“…In [11], the outage time is reduced by adjusting the speed of the target vehicle to extend the communication time with the selected relay vehicle. A bivious SCF scheme is proposed in [12], which minimizes the outage time by selecting forward and backward relays.…”

“…In addition, the speed of the target vehicle is adjusted to extend the communication time. The main drawback of the works in [11] and [12] is that the problem of speed adjusting is solved using the interiorpoint method that inevitably involves large number of iterations [2]. The SCF scheme proposed in [2], on the other hand, minimizes the outage time by selecting two relays one from each traffic direction.…”

“…We also assume that BSs and vehicles are capable of FD communications and are equipped with isolated antennas for transmission and reception. Similar to the works in [2]- [4], [11]- [13], we investigate the downlink communication scenario in which a target vehicle V o may request a large amount of data that cannot be received entirely inside the BS coverage. To provide a persistent service, one of the vehicles is selected to act as a relay by buffering part of or the entire remaining data that cannot be delivered to V o inside the BS coverage to be relayed to V o in the UA.…”

We consider intermittently connected vehicular networks (ICVNs) in which base stations (BSs) are installed along a highway to connect moving vehicles with internet. Due to the deployment cost, it is hard to cover the entire highway with BSs. To minimize the outage time in the uncovered area (UA), several store-carry-forward (SCF) schemes have been proposed in which a vehicle is selected to act as a relay by buffering data to be relayed to a target vehicle in the UA. In this paper, we propose a full-duplex (FD) SCF scheme that exploits the relay's ability to simultaneously receive and transmit in order to improve the effective communication time (ECT) with the target vehicle and accordingly deliver more data to it in the UA. The optimal power allocation (PA) that maximizes the ergodic capacities of the links is determined and the amount of data that can be buffered inside the BS coverage and can be delivered by each relay candidate to the target vehicle in the UA is found. Since the relay cannot deliver more data in the UA than what can be buffered inside the coverage, the performance of each relay candidate is limited by the minimum of the two amounts and hence is used as a relay selection (RS) criteria. To reduce the computational complexity, an alternative RS scheme that selects the relay candidate that offers the highest ECT is proposed. As compared to half-duplex SCF schemes, simulation results show that the proposed FD schemes are capable of delivering significantly higher amount of data to the target vehicle in the UA.

In VANET, vehicles are move very fast as a consequence intermittent connectivity occurs frequently. In this delay-tolerant situation, the emergency rescue message broadcast is an extremely challenging task. The proposed routing protocol REMD give a solution to the problem. REMD follow the store carry forward method and flooding based message forwarding method. This paper expresses rapid emergency message dissemination routing in delay tolerant network called REMD Protocol. In this protocol, the source vehicle broadcast emergency message to the presented all neighbour vehicles in its communication range. The sender vehicle allocates message replicas and message time to live to the neighbour vehicles based on the corresponding vehicles credence value. Each vehicle credence value is calculated from their Visited Level Estimation (VLE) and Destination Reaches Level Estimation (DLE) values.

Vehicular ad hoc networks (VANETs) are the special type of mobile ad hoc networks (MANETs) that are very frequent network in which partitions are caused by node mobility. Delay tolerant network (DTN) follows the approach to store and forward the message. Delay Tolerant Networks (DTN) are the networks which do not require the immediate data delivery and these networks can wait for a specific time period before transferring of data. VANET introduces lot of challenges because of high mobility of the nodes and fast topology changes in the VANET. Various kind of routing protocols have been designed and presented by the researchers after considering the major challenges that are involved in DTN enabled VANETs. This paper provides a survey of the VANET, DTN and routing protocols for DTN enabled VANET.
