Secure, Efficient and Privacy-aware Framework for Unstructured Peer-to-Peer Networks
Recently, the advances in Ubiquitous Computing networks and the increased computational power of network devices have led designers to create more flexible distributed network models using decentralised network management systems. Security, resilience and privacy issues within such distributed …

A game-theoretic network formation model
… network formation model that yields large-scale small-world networks. So far, mostly stochastic frameworks have been utilized to explain the emergence of these networks. On the other hand, it is natural to seek for game-theoretic network formation models in which links are formed due to strategic …

Knowledge networks and innovation policy
… and shared through non-market based knowledge networks. Those organizations which exploit networks as a source of knowledge gain competitive advantage over those which do not. Organizations often underinvest in forming and sustaining network relations. This justifies the public support of …

In Search of Homo Sociologicus
… multiple methods of belief revision in social networks. Such belief revision in groups represents social influence and power to some degree. Both influence from friends and from experts are explained.</p> <p>We define an intuitive concept of expected influence of a group. When different …

Simulated Associating Polymer Networks
<p>Telechelic associating polymer networks consist of polymer chains terminated by endgroups that have a different chemical composition than the polymer backbone. When dissolved in a solution, the endgroups cluster together to form aggregates. At low temperature, a strongly connected reversible …

Robustness of complex networks to global perturbations
… studies the robustness of complex dynamical networks with non-trivial topologies against global perturbations, following Robert May’s seminal work on network stability, in order to find critical stability thresholds of global perturbations and to determine if their impact varies across …

Simulating high-throughput cryptocurrency payment channel networks
… transactions with few blockchain broadcasts. Networks of payment channels have emerged as a proposed solution to Bitcoin’s scaling problem. Since the proposal of the first payment channel network, the Lightning Network, alternatives promising significant improvements, such as the Sprites …

Mathematical modelling and brain dynamical networks
… electrical coupling gl. We show that, even for small number of neurons, the dynamics of the system depends on the number of neurons and the type of coupling strength between them. Finally, we evolve a network of Hindmarsh-Rose neurons by increasing the entropy of the system. In particular, we …

Algorithms For Discovering Communities In Complex Networks
It has been observed that real-world random networks like the WWW, Internet, social networks, citation networks, etc., organize themselves into closely-knit groups that are locally dense and globally sparse. These closely-knit groups are termed communities. Nodes within a community are similar in …

Changing edges in graphical model algorithms
… as the nodes in decoding circuits, agents in small-world networks, and neurons in our brains. These structures are often not static and can change over time, resulting in removal of edges, extra nodes, or changes in weights of the links in the graphs. For example, wires in message-passing …

Essays in Networks and Experimental Economics
The thesis focuses on networks and experimental economics. The first chapter theoretically studies network coordination games under adaptive learning agents. The second and third chapters conduct experiments on strategic interactions in networks and on network formation, respectively. The fourth …

The Effects of Chronic Sleep Deprivation on Sustained Attention: A Study of Brain Dynamic Functional Connectivity
… was modeled as a series of dynamic functional networks in each experimental condition. Graph theoretic analysis was performed to investigate the dynamic properties of brain functional networks, using network measures of clustering coefficient and characteristics path length. In the chronic …

Measuring Political Activity How Online and Offline Political Activities Connect
… are essentially built upon interpersonal networks. However, the specific network structures of these platforms are often undisclosed. To explore how these attributes influence the dissemination of information, this thesis employs an agent-based model to simulate the dynamics of the social …

Behavior-based Incentives for Node Cooperation in Wireless Ad Hoc Networks
… cooperation, on topology control in ad hoc networks. Our work is among the first to consider selfish behavior in the context of topology control. We create topologies based on a holistic view of energy consumption " energy consumed in forwarding packets as well as in maintaining links. Our …
