MANET Based Emergency Communication System Design During Disaster and Post Disaster

In the event of a natural disaster most of the communication networks become unavailable either because of damages sustained to the infrastructure such as antennas and other communication devices or because of power failure. During these times, communication plays a vital role in keeping the people informed about post disaster effects in the affected areas. There are two aspects in this circumstance. One is to immediately locate the affected persons and provide emergency assistance. The other is to offer calamity release during and after the disaster. The conventional method of establishing communication is usually done by establishing emergency command center and hosting the entire essential telecommunication infrastructure to provide communication between members of the search and recovery teams. This type of solution is expensive, tough to maintain, and the level of reliability is low. Because of these reasons the efficiency of the system is less. For improving the effectiveness of the communication during the times of natural calamity is to implement a communication system that does not rely on infrastructure based equipments. The proposed system makes use of Mobile Ad-Hoc Network (MANET) based communication. The proposed system also incorporates Global Positioning System (GPS), a satellite based location detection system that could be used to pinpoint a particular person who is in distress. Geographic Information System (GIS) and Remote Sensing (RS) are essential for effective preparedness, communication, and training tool for calamity management.
