Basically, the recovery structure includes a network which can be used when all other networks are collapsed. It will be usable in any emergency situation. For example, the picture below depicts the fall of the Margalla towers in the year 2008, due to the earthquake. At that time all the networks had stopped working. CrANs can be used in these situations as a recovery network. It will be operatable if even a few nodes are available whether MANETs or FANETs.

In a third world country like Pakistan, no proper replacement for other networks works properly. In these type of emergency situations (which are quite frequent), CrANs can be used as a substitute. It does not require a strong infrastructure to be made.
