SSTIF: Stable Self-Organized Infrastructure-based Peer-to-Peer Network

This study presents a stable self-organized infrastructure-based (SSIF) P2P networking scheme to build an infrastructure-based model (IFM) P2P network with both location aware and stable clustering features. SSIF employs clustering and infrastructure node election to construct an IFM P2P network. The clustering divides peers into many clusters according to their geographical proximity. A novel positioning scheme called dynamic hybrid network positioning (DHNP) was proposed to offer accurate peer coordinates. SSIF makes a peer join a cluster with gravity close to its position. SSIF also associates each peer with a novel metric power that represents the capability and stability of the peer. According to the power of peers, peers are elected as cluster leaders or infrastructure nodes to offer stable and high-performance services in the P2P network. Finally, SSIF adopted a novel concept called confederation to achieve the stability of a search domain to offer efficient resource search. Simulation results confirm that SSIF does offer very stable and high-performance service than previous P2P systems.
