Modeling the diffusion of information through such networks is crucial for our modern information societies. In this work, novel models, segregating between useful and malicious types of information, are introduced, in order to better study Information Dissemination Dynamics (IDD) in wireless complex communication networks, and eventually allow taking into account special network features in IDD. According to the proposed models, and inspired from epidemiology, we investigate the IDD in various complex network types through the use of the Susceptible-Infected (SI) paradigm for useful information dissemination and the Susceptible-Infected-Susceptible (SIS) paradigm for malicious information spreading. We provide analysis and simulation results for both types of diffused information, in order to identify performance and robustness potentials for each dissemination process with respect to the characteristics of the underlying complex networking infrastructures. We demonstrate that the proposed approach can generically characterize IDD in wireless complex networks and reveal salient features of dissemination dynamics in each network type, which could eventually aid in the design of more advanced, robust, and efficient networks and services.","PeriodicalId":272225,"journal":{"name":"Journal of Complex Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127927576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bag","doi":"10.1155/2013/591513","DOIUrl":"https://doi.org/10.1155/2013/591513","url":null,"abstract":"We have studied in this paper the dynamics of globally coupled phase oscillators having the Lorentzian \u0000frequency distribution with zero mean in the presence of both time delay and noise. Noise may \u0000be Gaussian or non-Gaussian in characteristics. In the limit of zero noise strength, we find that \u0000the critical coupling strength (CCS) increases linearly as a function of time delay. Thus the role \u0000of time delay in the dynamics for the deterministic system is qualitatively equivalent to the effect \u0000of frequency fluctuations of the phase oscillators by additive white noise in absence of time delay. \u0000But for the stochastic model, the critical coupling strength grows nonlinearly with the increase of \u0000the time delay. The linear dependence of the critical coupling strength on the noise intensity also \u0000changes to become nonlinear due to creation of additional phase difference among the oscillators \u0000by the time delay. We find that the creation of phase difference plays an important role in the \u0000dynamics of the system when the intrinsic correlation induced by the finite correlation time of the \u0000noise is small. We also find that the critical coupling is higher for the non-Gaussian noise compared \u0000to the Gaussian one due to higher effective noise strength.","PeriodicalId":272225,"journal":{"name":"Journal of Complex Systems","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124597365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
