Underwater acoustic sensor network for early warning generation

There is an ever felt need to create an efficient comprehensive system to tackle natural hazards such as Tsunamis, earthquakes, landslides and floods by providing a timely early warning. Underwater wireless sensor network (UWSN) seems to be one promising solution. The success of mobile wireless communication in terms of power efficiency and reliability needs to be repeated with the UWSN for fighting the havoc of nature. An integrated system for early warning generation which would provide information globally is proposed. This paper highlights the physical layer challenges in establishing a reliable, low power consuming and long life UWSN system for early warning generation.
