Appendix I

Efficient and resilient data dissemination in a disaster area

Figure I.1 shows the packet loss as a function of the number of connections that simultaneously connect to
an original content holder located at the top of a tree topology. Due to the in-network caching function of
DAN, contents originally located at the top of a tree topology are gradually distributed to the in-network
caches in the network, which enables DAN to provide an efficient as well as resilient data dissemination
scheme for any disaster scenario. The simulation was carried out based on named data networking (NDN) [b-
Jacobson, 2009], which is an example of an implementation of DAN.
