Guaranteed broadcasting using SPON: supervised P2P overlay network

One important application for dynamic networks is broadcast or multicast communication, where a single message is sent to all members of a dynamic set of recipients. This functionality is required by many data-sharing protocols, as well as applications including media streaming, online gaming, teleconferencing, and distance education. This paper proposes a tree-based network called SPON which manages group updates and supports efficient broadcasting. SPON uses a supervisor peer to maintain the network during node arrivals and departures and routes broadcasts using direct connections between nodes.
