Abstract

World is a happening ground for the disasters almost daily. These incidents of mass destruction irrespective of the whether natural calamities or man-made catastrophes cause a huge loss of money, property and lives due to non-planning on the part of the governments and the management agencies. Therefore steps are required to be taken towards the prevention of these situations by pre determining the causes of these disasters and providing quick rescue measures once the disaster occurs. Wireless Ad hoc sensor networks are playing a vital role in wireless data transmission infrastructure and can be very helpful in these situations. Wireless sensor networks utilize the technologies which can cause an alert for the immediate rescue operation to begin, whenever this disaster is struck. Through this paper our aim is to review technological solutions for managing disaster using wireless sensor networks (WSN) via disaster detection and alerting system, and search and rescue operations. We have first discussed the basic architecture of WSNs that can be helpful in disaster management and the wireless sensor network models that can be employed for the different disaster situations. Finally, we propose how these networks can be effective in Indian scenario which lags behind the developed world in basic infrastructure amenities.
