Smartphones based warning messaging system for marine fisheries and its characteristics

There are still many communities that are far behind from having the benefits of modern communication systems. The marine fisheries of developing countries corresponds to such a scenario which as it is suffering a lot due to lack of a flexible and reliable warning system which could make the fishermen lives safer at sea. This paper proposes a warning message broadcasting system for marine fishing boats exploiting smartphones available to the fishermen with other comparatively inexpensive wireless communication devices. The Multipoint Relay (MPR) broadcasting protocol is enhanced to distribute warning message. Thus MPR can disseminate message to the large number of users distributed sparsely over the large area of marine fishing zone. The proposed system is evaluated for the marine fishing of Bangladesh using NS-2. The system can forward messages to 98% users. The system would be flexible and cheap for fishermen. Besides, small budget is needed for installing and maintaining the system.
