It is difficult to propagate disaster management information rapidly among clients when some local network breakdown takes place. By applying percolation theory to propagate newly defined reverse-query messages over the unstructured P2P network, we propose novel information delivery network architecture built over existing unstructured P2P network. We analyzed our algorithm and examine the validity of our model, that will cover more than 80% of all the clients ,with relaying reverse-query messages under probability as low as 10%, being effective drastically to reduce the total traffic generated by query propagation. This architecture can be a solution for presenting information to many people in the devastated area over the Internet in case of natural calamity.
