— It is possible to recover the original data from a certain amount of encoded data by using rateless codes, which are utilized for multicast streaming. In this paper, we propose an effective replication technique using rateless codes for unstructured P2P networks. More specifically, we propose a method to spread and find chunks generated from files(More)
— The aim of this study is to propose an efficient broadcasting method considering node density and to conduct a comparative evaluation with existing methods. In our proposed method, broadcasting is carried out efficiently using positional information attached to messages at the time of broadcasting and not by periodically exchanging positional information(More)
