P2P VoIP systems. ...
We use the term Small World to refer to the Peer-to-Peer (P2P) network of a client and his contacts both incoming and outbound. ...
Therefore, we leverage the structural properties of the small world network of the telephone call graph for each user to efficiently route call connection requests, we call our approach SW-VoIP. ...

To conquer these problems, we propose a hierarchical social network-based P2P SIP system. The social network property can increase routing efficiency when calling friends. ...
In addition, we improve lookup efficiency from O(logN) to O(1) when making calls with buddies, where N is the number of nodes in a DHT-based network. ...
In large P2P networks, each node directly connects to a group of neighbors and uses these connections to reach the other nodes in the network. ...

In the last section, an enhancement to these mechanisms is proposed which lifts some of the previously seen limitations, especially the DoS risks, the token storage constraint or the transport impact of ...
In brief, each node of the P2P network is a call agent (CA) for a given VoIP domain. Each CA publishes in the P2P DHT all the user identifiers held by the domain. ...
