Abstract : In a maritime environment, affordable long range communication network for fishing vessels are highly necessary for safety at sea and to communicate to shore and back to the fishing vessels. The existing communication architecture faces major challenges in achieving seamless connectivity due to the mobility of fishing vessels, lack of backbone infrastructure, propagation effects, and fault tolerance. In this work, we explored the capability of Delay Tolerant Networks (DTN) for providing better connectivity under the above mentioned parameters. Existing DTN protocols such as Epidemic, Spray and Wait and MaxProp protocols were studied and analyzed for maritime scenario. These protocols were simulated in Opportunistic Networking Environment (ONE) simulator and analyzed with respect to node density, node mobility, and intermittent connectivity. The results show that Epidemic protocol has moderate average latency, whereas Spray and Wait protocol and MaxProp has better data delivery rate with lesser average latency.
