Disaster management is management of tasks involving responses to emergencies and methods of devising recovery strategies from havocs caused by nature. It assumes paramount importance now as the human surrounding has enormously become unpredictable owing to natural or man-made disasters. Consequence of disaster can be reduced by broadcasting of disaster alert to a defined radius that could be affected by the disaster. The objective of disaster management is to ensure energy economical and reliable communication that is resilient to network topology changes within the area. Vehicular ad hoc network (VANET) is efficiently utilized to transfer the disaster alert information. Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communication is used for disseminating the disaster alert message. This study proposes an effective data acquisition from the disaster location, data dissemination to the neighbouring zones and disaster management using VANET technology.
