Ensuring fishermen safety through a range based system by trizonal localization using low power RSSI

In the proposed system a solution is given to the problem of “Fishermen Tracking their location in the sea”. For this the sea area is divided into three zones namely; safe, intermediate and danger. The boat is allowed to roam anywhere within the safety zone. If the boat reaches the intermediate zone, a buzzer alert is given to the fisherman. If the boat reaches the danger zone, an intimation is given to the fisherman where he is supposed to reach the intermediate zone within the specified time. Else the engine gets stopped automatically and the control of the boat goes to the control room The boat will be released only after inspection by the coast guard or after the emergency help is given. The different Ranges are identified using Received Signal Strength Indicator(RSSI).
