Information Epidemics in Complex Networks With Opportunistic Links and Dynamic Topology

Wireless networks, especially Mobile Ad hoc NETworks (MANET) and Cognitive Radio Networks (CRN), are facing two new challenges beyond traditional random network model: opportunistic links with random nature due to fading and dynamic channel access, and dynamic network topology due to mobility and time varying. For a more general networking of Internet users as social complex networks, such challenges of further importance remain open. A generic and reliable model is therefore required to capture the Information Dissemination Dynamics (IDD) of machine-to-machine communications or interactions in relation-based social networks. Inspired from epidemiology, the authors investigate the IDD in well-known complex networks by modified Susceptible-Infected (SI) model, which is surprisingly suitable for above multiple scenarios.
