Abstract
Vehicular Delay-Tolerant Networks use the delaytolerant
architecture and protocols to overcome the disruptions in
network connectivity. These concepts help in cases where the
network is sparse or with large variations in density or there is no
end-to-end connectivity, by providing a communications solution
for non real-time applications. This paper presents data
fragmentation techniques to optimize the efficiency of data
delivery for the case of the short node contacts that characterize
vehicle networks. The techniques were tested in a laboratory
environment with portable digital assistants and Lego Mindstorm
NXT robotic cars. If no fragmentation is used, only small
messages are successfully transferred. Proactive fragmentation
fragments messages to a predefined size in the source node.
Reactive fragmentation adjusts the fragment sizes to the real
duration of the contact when it is broken. Reactive fragmentation
showed a good efficiency in adapting the fragmentation in real
time to the contact duration. Proactive fragmentation can
perform slightly better if the fragment sizes are carefully chosen
as it requires less processing. As this choice is difficult, reactive
fragmentation is more practical to use.
