Many lives are in danger at sea in the events of an unforeseen storm, cyclones, and other natural disasters. One of the major difficulties faced by the rescue team in such an event is the difficulty to locate the personnel in danger. Our project aims at solving this issue by incorporating a chip that helps fishermen in sending distress signals to the shore while in danger. The signal will contain the location of the person. Repeaters are meant to be placed at buoys that helps in transmitting the signal from the source to the destination. Our project includes the study and selection of hardware devices and network specifications. The specifications of potential hardware, network topology and routing protocols are collected and studied. This is compared with each other and the most optimum hardware components and network specifications are selected. The selection of these components were made based on their power consumption, range, data rates etc. Selection of network properties were made based on their efficiency, reliability and economic factors.
