Abstract :
Changes in Global climate is increasing the occurrence of extreme climate phenomenon with increasing severity, both in terms of human casualty as well as economic losses. Authorities need to be better equipped in order to face these disasters. An efficient disaster detection and alerting system can help in reducing the loss of life and properties. A 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 of natural calamities such as floods, tsunami, hurricanes, etc. and can provide the rescue operation immediately. This paper aim to review technological solutions for disaster management using Wireless Sensor Network(WSN) via disaster detection and alerting system using wireless sensor(Bluetooth). The use of WSN can replace the traditional network for disaster management which involves a huge hardware circuitry such as landline and optical cable network. Wireless networks are easy to maintain and cost effective and have lot of advantages compared to traditional wired networks.
