Routing protocols for DTN in vehicular environment

Abstract

Delay Tolerant Networks (DTN) are utilized in various operational environments, including those subject to disruption and disconnection and those with high-delay, such as Vehicular ad-hoc Networks (VANET). Through relays and carry and forward, messages, in DTN, can be delivered to the destination without an end-to-end connection for delay-tolerant applications. The choice of routing algorithms, in DTN, is still under study. The main objective of routing protocols in DTN is to maximize the probability of delivery at the destination while minimizing the end-to-end delay. The aim of this paper is the comparison between routing protocols dedicated to VANETs, which will enable us to propose transaction services with sufficient round-trip delay for a large number of applications, using only short-distance communications between vehicles and between vehicles and infrastructure. This would limit the use of long distance transmission and thus decrease the electromagnetic pollution.

 Delay Tolerant Networks (DTN) are utilized in
various operational environments, including those subject to
disruption and disconnection and those with high-delay, such as
Vehicular ad-hoc Networks (VANET). Through relays and carry
and forward, messages, in DTN, can be delivered to the
destination without an end-to-end connection for delay-tolerant
applications. The choice of routing algorithms, in DTN, is still
under study. The main objective of routing protocols in DTN is to
maximize the probability of delivery at the destination while
minimizing the end-to-end delay. The aim of this paper is the
comparison between routing protocols dedicated to VANETs,
which will enable us to propose transaction services with
sucient round-trip delay for a large number of applications,
using only short-distance communications between vehicles and
between vehicles and infrastructure. This would limit the use of
long distance transmission and thus decrease the electromagnetic
pollution.
