概要 An object is a unit of resource distributed in peer-to-peer (P2P) overlay networks. Service supported by an object is modeled to be a set of methods and quality of service (QoS). It is critical to discuss what peer can manipulate an object in what method, i.e. only a peer granted an access right can manipulate an object. In this paper, we take an acquaintance approach. An acquaintance of a peer p is a peer whose service the peer p knows and with which the peer p can directly communicate. We discuss types of acquaintance relations of peers with respect to what objects each peer holds and what access rights each peer is granted and can grant to another peer. Acquaintance peers of a peer may notify the peer of different information on target peers. Here, it is critical to discuss how much a peer trusts each acquaintance. We define the trustworthiness of an acquaintance in terms of the acquaintance relations among the peers. In addition, we present a charge-based flooding (CBF) algorithm to find target peers based on trustworthy acquaintances so that more trustworthy areas are more deeply searched.
