Abstract: Many areas of world are getting affected due to natural calamity. Disasters are exceptional & unstoppable events that are either man made or natural, such as terrorist attacks, earthquakes, wildfires and floods etc. Disasters create emergency situations to provide basic services to the victims must be coordinated quickly. Many times we observe that many people dies by trapping in these disasters but the people also dies on large scale just because they didnít get help at instant time or the help provided to them is late. This project proposes a system based on Wireless Sensor Network (WSN) which is designed for human existence & detection in an unmanned area can be done only by an automated system. This system proposed a monitoring system using sensors unit and transmit data. Mobile robots perform cooperative Simultaneous human body localization function and communicate over the WSN. The main objective of this thesis is to rescue more & more number of people from the adverse condition.
