Disaster Management System using Wireless Sensor Network: A Review

Due to the changes in the environment natural catastrophe is increasing day by day. Any hazardous incident can happen at any time, with that effect lot of people loss their life, property. These calamities can be of any type weather it can be natural or human induced cause mass devastation. Wireless Sensor Network (WSN) is very realistic and demandable technology from past few years which can be supportive in monitoring and managing disaster. In this paper, we are describing the WSN architecture and how it works. Another is the types of disaster and the sensors which are used to compute their intensity. After that, a survey is done on the literature in which the issues, technologies and protocols used and their solutions are explained. An architecture of early warning system for disaster detection in WSN is elucidated which can be helpful in detecting, alerting and rescuing operation.
