基于谣言的流言中的可靠和不可靠来源

Reliable and Unreliable Sources in Age-Based Gossiping

Priyanka Kaswan, Sennur Ulukus

摘要:

我们考虑一个网络组成的$n$节点,旨在跟踪一个不断更新的过程或事件。为了向网络传播关于该事件的最新情况,有两个来源,因此从一个来源获得的信息被认为比另一个来源更可靠。节点希望能够访问关于事件的信息,该信息不仅是最新的,而且是更可靠的,并且与不可靠的分组相比更喜欢可靠的分组,即使前者相对于后者有点过时。我们研究了这种偏好如何影响网络中具有可靠信息的用户的比例以及他们的信息版本年龄。我们推导出的解析方程来表征两个数量,长期预期分数的节点可靠的数据包和他们的长期预期版本年龄使用随机混合系统(SHS)建模和研究他们的属性。我们还比较了这些结果的情况下,节点给更多的偏好,信息的新鲜度比它的可靠性。最后,我们展示了仿真结果来验证理论结果,并进一步阐明了上述量相对于因变量的行为。

英文摘要:

We consider a network consisting of $n$ nodes that aim to track a continually updating process or event. To disseminate updates about the event to the network, two sources are available, such that information obtained from one source is considered more reliable than the other source. The nodes wish to have access to information about the event that is not only latest but also more reliable, and prefer a reliable packet over an unreliable packet even when the former is a bit outdated with respect to the latter. We study how such preference affects the fraction of users with reliable information in the network and their version age of information. We derive the analytical equations to characterize the two quantities, long-term expected fraction of nodes with reliable packets and their long-term expected version age using stochastic hybrid systems (SHS) modelling and study their properties. We also compare these results with the case where nodes give more preference to freshness of information than its reliability. Finally we show simulation results to verify the theoretical results and shed further light on behavior of above quantities with respect to dependent variables.
