IP Telephony is a potential killer application among the various multimedia applications and services. It is therefore natural to expect support for these services over new network architectures like wireless ad-hoc networks. Despite the proliferation of IP Telephony services in the Internet, the traditional client/server models that have been used are found to be highly inefficient for wireless ad-hoc networks as compared to Peer-To-Peer (P2P) models. On the other hand, P2P strategies require some tuning to work well in wireless ad-hoc networks. In this paper, the authors discuss some undesirable situation that may happen if P2P systems are deployed over wireless ad-hoc networks without adaptation.
