Delay Tolerant Networks Architecture, Protocols, and Its Application in Vehicular Ad-Hoc Networks

Abstract

Due to the high mobility of vehicular nodes in VANETs, there are high chances of partitions in the network. In such a situation, the protocols developed for VANETs cannot work well and an alternative network known as DTN (delay tolerant network) is capable enough to deal with VANET characteristics. The network which does not need any immediate data delivery and can wait for time and delivery of data is known as DTN. The concept of hold and forward the message is exploited by DTN. In this chapter, the authors are providing characteristics, architecture, and applications of delay tolerant vehicular ad-hoc networks.
