   * //Routing Stretch// \\ Routing stretch metric is the ratio between the cost fo selected route using the overlay=neighbor to the optimal shortest path routing through the MANET. So minimizing routing stretch is a critical issue for a multi-hop environment, as otherwise both delay and packet loss will be increased.   * //Routing Stretch// \\ Routing stretch metric is the ratio between the cost fo selected route using the overlay=neighbor to the optimal shortest path routing through the MANET.

Distributed caching should be applied to store popular information.

-  * //Security// \\+  * //Security// \\ Security in P2P over MANET is quite challenging and could require use of public keys, etc, and hence depends on a PKI. PKI sotres digital certificates that attach a public key to the name of the owner by the digital signature of a trusted peers - CAs. But maintaining this introduces some complexity due to the centralized nature of the PKI.
