DISASTER MANAGEMENT SYSTEM USING WSN

The mankind at present is facing a biggest challenge from natural calamities like floods, Tsunami, hurricanes etc due to several reasons like deforestation, land sliding and global warming. This is a major problem facing by many countries across the globe. We need to introduce an advanced mechanism to face the natural disasters and to reduce the damage caused over it. Using advanced technology helps us to alert the people in coastal areas before the natural calamities so we can protect the mankind and cattle over there. The wireless sensor networks play a crucial role in wireless data transmission and helps very much in this regard. Using Wireless sensor networks we can reduce the disaster effect and can provide the rescue operation immediately. Through this paper our aim is to review technological solutions for disaster management using Wireless Sensor Networks (WSN) via disaster detection and alerting system and search and rescue operations. In traditional networks involves a huge hardware circuitry such as landline and optical cable networks. Later Adhoc networks were replaced by traditional networks, in adhoc networks no centralized node is present and each node forwards the traffic to the neighbouring node. Huge traffic congestion is a backdrop for adhocs networks. Hence we go for Wireless Sensor Networks (WSN). The proposed system contains three nodes called sensing node placed in ocean, intimating node nearby coastal areas and coordinating node placed in base station respectively. Both sensing node and intimating node sends data signals to coordinating node, the coordinating node sends the data to the base station.
