Mobile ad-hoc networks rely on the cooperation of nodes for routing and forwarding. For individual nodes there are however several advantages resulting from noncooperation, the most obvious being power saving. Nodes that act selfishly or even maliciously pose a threat to availability in mobile adhoc networks. Several approaches have been proposed to detect noncooperative nodes. In this paper, w...

An infodemic often involving rumors, stigma,and conspiracy theories has been prevalent during the COVID-19 pandemic. Social media data monitoring identified as best method for tracking rumors in real-timeand a possible way to dispel misinformation and reduce stigma. However, identifying, assessing,and responding real-timeis complex task. Disinformation fueled by hearsay, can have potentially se...

This study aims to explore the time series context and sentiment polarity features of rumors’ life cycles, how use them optimize CNN model parameters improve classification effect. The proposed is a convolutional neural network embedded with an attention mechanism information. Firstly, whole cycle rumors divided into 20 groups by algorithm each group texts trained Doc2Vec obtain text vector. Se...

In this paper, we try to see how virtual networks can af- fect the behavior of the young. Since there are so many indices to be affected by social networks, we evaluate these effects only on 10 more comprehensive behaviors as follows: identity, getting information and the rumors, rationalism,life style, spare time, religions rituals and cer- emonies, interaction with family, employment and eco-...

Spreading truths is recognized as a feasible strategy for inhibiting rumors. This paper is devoted to assessing the effectiveness of the truth-spreading strategy. An individual-level rumor-truth spreading model (the generic URTU model) is derived. Under the model, two criteria for the termination of a rumor are presented. These criteria capture the influence of the network structures on the eff...

The riots of 2005 in Mocímboa da Praia and the current violent attacks Cabo Delgado province have resulted a range unsettling rumors. This article revisits their aftermath to make sense rumors that spread since then, fueling fears violence uncertainty. These disconcerting are especially rich what they tell us about perception political Other narratives materialize following events. way which ci...
