Toward Secure and Efficient Peer-to-Peer Voice over IP Communication in Large-scale Hierarchical Mobile Ad Hoc Networks
Abstract
Peer-to-Peer (P2P) Voice-over-Internet Protocol (VoIP) protocols are a logical choice for mobile ad networks (MANETs), as a MANET is also inherently a P2P network where each node moves from one place to another independently, joins and leaves the network as it wishes. P2P VoIP uses a distributed hash table (DHT) for routing among the nodes in the application layer. A large-scale scalable MANET topology is usually a hierarchical topology consisting of cluster heads that form the backbone of the MANET, and each cluster head controls a set of ordinary nodes that form an access MANET network. We propose to study two important aspects of deploying P2P-SIP over MANETs in a military context: security and efficiency (routing optimization). On the security front, we focus on protecting the DHT VOIP registry against various attacks. On the efficiency front, we look into various routing schemes in the hierarchical MANET backbone.
