TL;DR: Threats to the stability and security of the content distribution system are analyzed in theory, simulations, and practical experiments, and it is suggested that major architectural refinements are required prior to global ICN deployment in the real world.

TL;DR: It is proved that minimizing the number of PPNs is a NP-hard problem and proposed a fast greedy algorithm for scalability and the anonymity of external attackers is evaluated.

TL;DR: It is shown that for more than 20 recent botnets and over 87,000 C&C flows, CoCoSpot can recognize more than 88% of the C &C flows at a false positive rate below 0.1%.

TL;DR: A novel cross-layer module is proposed to accurately capture both the high heterogeneity of the IoT and the impact of the Internet as part of the network architecture and can achieve a global communication optimum and outperforms existing layered solutions.

TL;DR: It is proposed that the flocking behavior of birds can guide the design of a robust, scalable and self-adaptive congestion control protocol in the context of wireless sensor networks (WSNs).

TL;DR: The experimental evaluation performed confirms that the proposed policies are capable to properly dimension the system resources making the whole system self-adaptable respect to the workload fluctuation, allowing to save up to the 32% of resource allocation cost always in the respect of SLA constraints.

TL;DR: A set of building blocks for content delivery is identified and a comparison of content delivery solutions relying on the current Internet infrastructure with novel Information-Centric Networking approaches is compared.

TL;DR: A novel way is proposed to identify efficiently and accurately the ''best'' features by first combining the results of some well-known FS techniques to find consistent features, and then using the proposed concept of support to select a smallest set of features and cover data optimality.

TL;DR: The evaluation and analysis present the performance bounds of in-network caching on NDN in terms of the practical constraints, such as the link cost, link capacity, and cache size.

TL;DR: This work proposes a novel approach to automatic protocol reverse engineering based on dynamic program binary analysis and uses it to analyze the previously undocumented C&C protocol of MegaD, a spam botnet that at its peak produced one third of the spam on the Internet.

TL;DR: An exploratory study on 10 feature-oriented systems found that the majority of feature interactions could be detected based on feature-based specifications, but some specifications have not been modularized properly and require undesirable workarounds to modularization.

TL;DR: Five case studies are presented where macrocells, microcells, picocells and femtocells are deployed based on the number of mobile subscribers present in a region, mobile user traffic in that region and the area of the region where cellular coverage has to be provided.
