Delay tolerant based warning message broadcasting system for marine fisheries

Wireless communication has been incredibly successful to make life easier. Despite such development, many citizens are still far behind having the benefits of modern communication systems, especially low-income people in developing regions. The marine fishing community of Bangladesh corresponds to such a scenario as it suffers a lot due to lack of a proper warning system that could broadcast warning messages to every fishing boat when there is extreme sea weather. This project's aim is to develop a warning message broadcasting system for the marine fishing boats. To make this system inexpensive and easily accessible by fishermen, the Wi-Fi enabled phones available to the fishermen will be exploited with other wireless communication devices. This report presents the challenges and opportunities to implement this system combining Delay Tolerant Networks (DTN) with Mobile Ad-hoc Networks (MANET). The study has focused to find a suitable broadcasting protocol that will ensure fast propagation of warning messages with high reliability in this wide network environment. We have propsed a lightweight broadcasting protocol and conducted an initial evaluation of the network based on this protocol. We have also developed a new mobility model to simulate fishing boats based networks.
