Abstract

Such home networking technologies as UPnP have become common for users to connect their devices at home. In this paper, we propose Dynamic Overlay Topology Optimizing Content Search (DOTOCS) that enables flexible content searches while optimizing P2P overlay networks. DOTOCS allows nodes to change their logical links to reach other nodes that have frequent data transfers in fewer hops, providing users with a better chance of finding their desired contents in quicker downloading time. For this reason, DOTOCS is useful to establish efficient connections among UPnP gateways on unstructured P2P networks for content sharing. We implemented DOTOCS using a P2P simulator to evaluate and measure its performance. The simulation results proved that DOTOCS increases search performance by 30 to 40% compared with a simple content search method that omits optimization.
