Efficient P2P Service Control Overlay Construction to Support IP Telephony Services Over ad-hoc Networks

摘要

Wireless ad-hoc networks is the key technology for community networks and rural regions that lack an established networking infrastructure. On the applications front, IP Telephony is also a killer application among the various multimedia services. It is therefore natural that wireless ad-hoc networks are expected to provide IP Telephony services. In this paper, we define strategies for constructing a P2P service control overlay to support IP Telephony services in wireless ad-hoc networks with no mobility, and validate the efficiency of our approach via simulations. This service control overlay provides a critical component to the deployment of various session-based multimedia applications in wireless ad-hoc networks.
