A Self-organized Clustering-based Overlay Network for Application Level Multicast

Abstract

Peer-to-Peer Overlay networks enabling an end-end application level-multicast service have drawn enormous attention. This paper proposes a self-organized -Multicast Overlay Network ( - MON) that enables an efficient end-end application level multicast. The -MON is organized into MON-Clusters, where δ is the maximum physical number of hops between any two end-nodes in each MON-Cluster. Thus, end-users accessing from different areas are able to broadcast data into each MON-Cluster within a constant δ physical number of hops. However in a dense-mode, increasing the size of MON-Clusters induces a long logical diameter that manifests high stress per physical links and high delay to disseminate data. Thus, this paper limits the expansion of each MON-Cluster within a specific logical diameter μ. Each MON-Cluster is constructed with at most μ logical hops over δ physical hops. Thus, end-users are able to efficiently disseminate data into each MON-Cluster within μ logical hops over δ physical hops with reasonable stress per physical links and bandwidth consumption.
