Complex Networks: Information Theory and Collective Dynamics
نویسندگان
چکیده
In this report we briefly discuss about two aspects related to the understanding of complex networks’ structure and dynamics. First of all, is shown how we can use an Information theory approach to describe networks’ characteristics such as heterogeneity and assortativeness; in addition, some network models like “Random Graphs“ and “Lattice Networks“ are classified following that approach. After that, the collective dynamics will be presented with a focus on synchronization of identical, non-identical and chaotic oscillators.

In this paper, a generalization of the Kuramoto model is introduced by explicit consideration of deterministically time-varying periodic external force. In this model, the oscillator's natural frequencies and amplitude of collective oscillations are influenced by external forces with constant or random strengths. Then, the synchronization behavior of forced Kuramoto model is studied in some com...
متن کاملA Novel Caching Strategy in Video-on-Demand (VoD) Peer-to-Peer (P2P) Networks Based on Complex Network Theory
The popularity of video-on-demand (VoD) streaming has grown dramatically over the World Wide Web. Most users in VoD P2P networks have to wait a long time in order to access their requesting videos. Therefore, reducing waiting time to access videos is the main challenge for VoD P2P networks. In this paper, we propose a novel algorithm for caching video based on peers' priority and video's popula...
متن کاملInfluence of topology on neural networks based on the recognition of neural signatures
We study the emerging collective dynamics of a neural network model that emits and recognizes neural signatures with different network topologies in order to assess the capacity of a neural network to implement a signaturebased information processing strategy. Complex collective dynamics emerge in the proposed model in the presence of stimuli, i.e. specific incoming signatures. Results presente...

متن کاملCollective Chaos Induced by Structures of Complex Networks
Mapping a complex network of Ncoupled identical oscillators to a quantum system, the nearest neighbor level spacing (NNLS) distribution is used to identify collective chaos in the corresponding classical dynamics on the complex network. The classical dynamics on an Erdos-Renyi network with the wiring probability pER ≤ 1 N is in the state of collective order, while that on an Erdos-Renyi network...
