Quick, accurate damage assessment information is necessary for speedy and effective rescue response in the aftermath of a large natural disaster or man-made disaster. This paper addresses a robust networking scheme with ad hoc networks for a data collection system, expanding scalability of the network in a whole city, and maintaining secure access in order to detect extraordinary phenomena. We discuss a heterogeneous networks organized with an access network and sensor networks for damage monitoring in a disaster. A hopcount-based routing protocol is presented for the heterogeneous network. Some fundamental evaluations on reachability, packet delivery ratio and traffic were carried out. The results showed that selective flooding with hopcount-based routing is useful for sensor networks.
