||Delay and Disruption Tolerant Networking offers a new dimension for communications
environments which are not conducive to the use of traditional TCP/IP
networks. The area of DTN's, though immature in terms of practical usage and
deployment, provides great opportunities for research and analysis. There is
lot of work being done to develop frameworks, protocols and algorithms in this
There are many implementations for DTN protocols which oer different alternatives
and approaches. Each have their own advantages and disadvantages.
There are two major goals of this work.
First is to evaluate two implementations for DTN protocols with regards to
their performance, namely BUNDLE and SaFT. The idea is to first analyse the
protocols individually and then go for a comparative analysis if time permits.
Such an analysis also depends upon the inherent characteristics of the available
protocols which might not be feasible for a comparison.
Second is to analyse two different tools which can be used for simulations in
DTN environments. The tool selection is an important factor with regards to
any research work. A wrong choice here might cause delays which are fatal in
the end. A good choice however can speed up things and avoid unnecessary
delays. Two possible candidates have been evaluated in this regard. These are
Network Simulator tool (NS) and the Opportunistic Network Environment simulator(
ONE). NS is the most popular open source tool for computer networks
related simulation work. But since it is a general tool for almost all such simulations,
it lacks certain customized features for specific purposes. The ONE
simulator, on the other hand, is a tool which has been custom built for Delay
Tolerant Networks. An analysis of both will provide a sound basis for their
usage in scenarios related to Delay tolerant Networks.
