Abstract: The usage of SuperPeers has been proposed to improve the performance of both Structured and Unstructured Peer-to-Peer (P2P) networks. In this paper we explore a network-aware class of Lightweight SuperPeer Topologies (LSTs). The proposed LST is based on the geometric principle of Yao-Graphs, a class of graphs allowing the development of simple and efficient broadcast algorithms. The pre-requisite of the LST approach is a function for mapping nodes in a network into a geometric space. In this paper we use the ”Highways ” proximity clustering and geometric placement model, introduced by one of the authors for this purpose. LST is evaluated based on PlanetLab measurements. 1
