Multimedia objects are distributed and replicated in peer-to-peer (P2P) networks since the objects are cached, downloaded, and personalized in local peer computers. Thus, various types of replicas of objects are distributed in various types and large number of peer computers. An application has to find target peer computers, which support objects with enough quality of service (QoS) required. We discuss a new type of flooding algorithm to find target peers based on charge concept so that areas where target peers are expected to exist are more deeply searched. In addition, we discuss how to obtain access rights and ask other peers to manipulate objects.
