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.
