The String of Diamonds Is Tight for Rumor Spreading. [PDF]

open access: yesCoRR, 2017
For a rumor spreading protocol, the spread time is defined as the first time that everyone learns the rumor. We compare the synchronous push&pull rumor spreading protocol with its asynchronous variant, and show that for any n-vertex graph and any starting vertex, the ratio between their expected spread times is bounded by O(n^{1/3} log^{2/3} n).

Faster Rumor Spreading with Multiple Calls [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2013
We consider the random phone call model introduced by Demers et al., which is a well-studied model for information dissemination on networks. One basic protocol in this model is the so-called Push protocol which proceeds in synchronous rounds. Starting with a single node which knows of a rumor, every informed node calls in each round a random neighbor ...

Asymptotic Stability of a Rumor Spreading Model with Three Time Delays and Two Saturation Functions

open access: yesMathematics
Time delays and saturation effects are critical elements describing complex rumor spreading behaviors. In this article, a rumor spreading model with three time delays and two saturation functions is proposed.

A Dual Rumor Spreading Model with Consideration of Fans versus Ordinary People

open access: yesMathematics, 2023
The spread of rumors in online social networks (OSNs) has caused a serious threat to the normal social order. In order to describe the rumor-spreading dynamics in OSNs during emergencies, a novel model with consideration of fans versus ordinary people is

A Rumor Spreading Model considering the Cumulative Effects of Memory [PDF]

open access: yesDiscrete Dynamics in Nature and Society, 2015

Spreading Dynamics of a 2SIH2R, Rumor Spreading Model in the Homogeneous Network

open access: yesComplexity, 2021
With the rapid development of social network in recent years, the threshold of information dissemination has become lower. Most of the time, rumors, as a special kind of information, are harmful to society.

Randomized Rumor Spreading in Dynamic Graphs [PDF]

open access: yes, 2014
We consider the well-studied rumor spreading model in which nodes contact a random neighbor in each round in order to push or pull the rumor. Unlike most previous works which focus on static topologies, we look at a dynamic graph model where an adversary is allowed to rewire the connections between vertices before each round, giving rise to a sequence ...

Global stability of a SEIR rumor spreading model with demographics on scale-free networks

open access: yesAdvances in Difference Equations, 2017
In this paper, a new SEIR (susceptible-exposed-infected-removed) rumor spreading model with demographics on scale-free networks is proposed and investigated. Then the basic reproductive number R 0 $R_{0}$ and equilibria are obtained.
