A Mobile Ad Hoc Network (MANET) is a self determining system containing a collection of two or more nodes connected through some kind of wireless communications and networking capability which enables them to communicate with each other. It doesn’t require any centralized server. This enables the wireless nodes to form a network dynamically to exchange information. It doesn’t requireany preexisting fixed network infrastructure. In the autonomous system hosts are free either to behave as nodes or act like routers at a time. In this paper, we study these advantages of MANET for disaster management. Disaster is a sudden accident or a natural catastrophe that causes great damage to life and it causes damaged networks in that particular area. As MANET is wireless networking system which is on demand technology, can used in such places as a rescue for the damaged networks and can be of great use in disaster management.
