Abstract 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 area. 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.
