I/O-efficient calculation of H-group closeness centrality over disk-resident graphs
August 2017
Information Sciences: an International Journal: Volume 400 Issue C, August 2017
Publisher: Elsevier Science Inc.
We introduce H-group closeness centrality in this work. H-group closeness centrality of a group of nodes measures how close this node group is to other nodes in a graph, and can be used in numerous applications such as measuring the importance and influence of a group of users in a ...

Security importance assessment for system objects and malware detection
July 2017
Computers and Security: Volume 68 Issue C, July 2017
Publisher: Elsevier Advanced Technology Publications
System objects play different roles in computer systems and exhibit different levels of importance to system security. Assessing the importance of system objects helps us develop effective security protection methods. However, little work has focused on understanding and assessing the importance of system objects from a security perspective. In this ...

Multi-Path TCP (MPTCP) is a new standardized transport protocol that enables devices to utilize multiple network interfaces. The default MPTCP path scheduler prioritizes paths with the smallest round trip time (RTT). In this work, we examine whether the default MPTCP path scheduler can provide applications the ideal aggregate bandwidth, i.e., ...

Computer Networks: The International Journal of Computer and Telecommunications Networking: Volume 119 Issue C, June 2017
Publisher: Elsevier North-Holland, Inc.
Content distribution networks have been extremely successful in todays Internet. Despite their success, there are still a number of scalability and performance challenges that motivate clean slate solutions for content dissemination, such as content centric networking. In this paper, we address two of the fundamental problems faced by any content ...

We investigate the capability of localizing node failures in communication networks from binary states normal/failed of end-to-end paths. Given a set of nodes of interest, uniquely localizing failures within this set requires that different observable path states associate with different node failure events. However, this condition is difficult to test ...

Covert Communication Gains From Adversary’s Ignorance of Transmission Time
December 2016
IEEE Transactions on Wireless Communications: Volume 15 Issue 12, December 2016
Publisher: IEEE Press
The recent square root law (SRL) for covert communication demonstrates that Alice can reliably transmit $\mathcal {O}(\sqrt {n})$ bits to Bob in $n$ uses of an additive white Gaussian noise (AWGN) channel while keeping ineffective any detector employed by the adversary; conversely, exceeding this ...

In this article, we investigate the traversal time of a file across N communication links subject to stochastic changes in the sending rate of each link. Each link’s sending rate is modeled by a finite-state Markov process. Two cases, one where links evolve independently of one another ( N mutually ...

In-network cache deployment is recognized as an effective technique for reducing content access delay. Caches serve content from multiple content providers, and wish to provide them differentiated services due to monetary incentives and legal obligations. Partitioning is a common approach in providing differentiated storage services. In this paper, we propose ...

Multi-Path TCP (MPTCP) is a new transport protocol that enables systems to exploit available paths through multiple network interfaces. MPTCP is particularly useful for mobile devices, which usually have multiple wireless interfaces. However, these devices have limited power capacity and thus judicious use of these interfaces is required. In this ...
