基于流言的信息传播建模框架

A Modeling Framework for Gossip-based Information Spread

Rena Bakhshi, Daniela Gavidia, Wan Fokkink, Maarten van Steen

摘要:

我们提出了一个分析框架的八卦协议的基础上,交互节点之间的成对信息交换。该框架允许研究协议参数对协议性能的影响。以前,基于流言的信息传播协议已经分析了完美的,无损的通信信道的假设下。我们扩展了我们的框架分析网络与有损通道。我们展示了如何存在的消息丢失,再加上特定的拓扑结构配置,影响预期的行为的协议。我们验证所获得的模型对模拟两个协议。

英文摘要:

We present an analytical framework for gossip protocols based on the pairwise information exchange between interacting nodes. This framework allows for studying the impact of protocol parameters on the performance of the protocol. Previously, gossip-based information dissemination protocols have been analyzed under the assumption of perfect, lossless communication channels. We extend our framework for the analysis of networks with lossy channels. We show how the presence of message loss, coupled with specific topology configurations,impacts the expected behavior of the protocol. We validate the obtained models against simulations for two protocols.
