TL;DR: It is shown that intelligent channel assignment is critical to Hyacinth's performance, and distributed algorithms that utilize only local traffic load information to dynamically assign channels and to route packets are presented, and their performance is compared against a centralized algorithm that performs the same functions.

TL;DR: A detailed performance evaluation shows that with intelligent channel and bandwidth assignment, equipping every wireless mesh network node with just 2 NICs operating on different channels can increase the total network goodput by a factor of up to 8 compared with the conventional single-channel ad hoc network architecture.

TL;DR: An efficient method to compute graph similarity that exploits structural and instruction-level information in the underlying malware programs, and a multi-resolution indexing scheme that uses a computationally economical feature vector for early pruning and resorts to a more accurate but computationally more expensive graph similarity function only when it needs to pinpoint the most similar neighbors.

TL;DR: This paper presents a compiler-based solution to the notorious buffer overflow attack problem, a taxonomy of defense methods, the implementation details of RAD, and the performance analysis of the RAD prototype.

TL;DR: Hancock is the first string signature generation system that takes on this challenge on a large scale and features a scalable model that estimates the occurrence probability of arbitrary byte sequences in goodware programs, a set of library code identification techniques, and diversity-based heuristics that ensure the contexts in which a signature is embedded in containing malware files are similar to one another.
