%X Information dissemination has become one of the most important services of communication networks. 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. 1. Introduction Information dissemination is a key social process in modern information-centric societies, and most of the communication infrastructures have been developed in the last thirty years mainly to allow transferring diverse types of information. Different information types range in scope (e.g., academic, educational, financial, and military), criticality (e.g., confidential, sensitive, public information, etc.), and value (e.g., useful, harmful, and indifferent). Recent advances in networking have been stimulated in order to accommodate emerging trends of increasing volumes and service demands of disseminated information. In general, information may be distinguished in three types, characterized by useful, malicious, or indifferent content. The first may consist of news, multimedia, or financial data. People are willing to accept such information, and usually such data is stored for further use, for example, e-books. Consequently, it is obtained once, and a user experiences a single transition from the state of not having it to the state of having received the information. On the other hand, users may get malicious information, such as malware, which however are in principle reluctant to accept and/or use.
