Vehicular delay tolerant network-A survey

The Vehicle based Delay Tolerant Networks (VDTNs) are emerging research topics that have attracted keen research efforts from both academia and industry. Delay tolerant networks are characterized by frequent network partitioning, intermittent network connectivity, long and variable delays, and high error rates. The DTN architecture model has been applied for vehicular networks called Vehicular Delay Tolerant Networks (VDTN). Such performance challenging conditions can be found in many different environments such as vehicular networks (VANET), in-thefield military or disaster-rescue networks, terrestrial networks serving remote or rural areas.

The connectivity pattern is unpredictable due to the destruction in communication infrastructures by the natural disaster. Hence in this research it focuses on providing a connectivity infrastructure with Vehicular Delay Tolerant Network (VDTN) robust to disaster effects. The main objective of routing protocols in VDTNs is to maximize the probability of delivery at the destination while minimizing the end-toend delay.

In this paper an attempt has been made to survey on VDTN having some basic features with new architecture which support a securable routing mechanism for an effective data packets forwarding. This paper also discussed about different types of protocols of vehicular delay tolerant network to support for the establishment of end-to-end connection effectively.
