This paper presents a two-level architecture for semantic P2P service discovery, which not only supports functionality-based service discovery but also provides flexible management mechanism for domain ontology. At the first level, a backbone is constructed on the basis of a category ontology, and the management task of domain ontology is distributed to the backbone peers on a per category basis....
Reduction of overhead is essential in increasing the scalability and power efficiency of peer-to-peer (P2P) file sharing systems for mobile ad hoc networks (MANET). Previously researchers mainly focused on reducing overhead of query process, and paid little attention to file transfer process. This paper presents a cluster-based P2P file sharing protocol for MANET, focusing on file transfer process...
