基于自愈局部交互的动态P2P覆盖图拓扑维护
On the Topology Maintenance of Dynamic P2P Overlays through Self-Healing Local Interactions
摘要:
本文讨论了使用自组织协议来提高动态对等(P2P)覆盖网络的可靠性。我们提出了两种方法,采用本地知识的第二邻域的节点。第一个方案是一个简单的协议,需要节点之间的相互作用和他们的直接邻居。第二种方案通过诉诸边缘聚类系数(ECC)来扩展这种方法,这是一种局部措施,可以识别连接覆盖中不同聚类的边缘。一个模拟评估,评估这些协议在均匀网络,集群网络和无标度网络。考虑了不同的失效模式。结果证明了该建议的可行性。
英文摘要:
This paper deals with the use of self-organizing protocols to improve the reliability of dynamic Peer-to-Peer (P2P) overlay networks. We present two approaches, that employ local knowledge of the 2nd neighborhood of nodes. The first scheme is a simple protocol requiring interactions among nodes and their direct neighbors. The second scheme extends this approach by resorting to the Edge Clustering Coefficient (ECC), a local measure that allows to identify those edges that connect different clusters in an overlay. A simulation assessment is presented, which evaluates these protocols over uniform networks, clustered networks and scale-free networks. Different failure modes are considered. Results demonstrate the viability of the proposal.
