  This paper presents an approach towards disaster management based on
cognitive radio ad hoc network. Despite the growing interests on cognitive
radio ad hoc networks, not much work has been reported on using them for
disaster management. This paper discusses opportunities for disaster management
based on cognitive radio ad hoc networks. In this direction, the paper presents
a novel technique for disaster detection based on Artificial Neural Network
(ANN). The ANN is trained using backward propagation algorithm. An ANN-based
spectrum sensing scheme is also presented. Finally, a service discovery scheme
is presented for coordination during the time of disaster. The simulation of
proposed approach has been performed in NS-2 simulator. The proposed approach
shows very low false negative alarm rate using the proposed disaster detection
system. The spectrum switching time of spectrum sensing scheme is also analyzed
along with an analysis of latency of proposed service discovery scheme
