Hop-by-hop quality of service routing
Computer Networks, 2001Abstract Based on the self-adaptive multiple constraints routing algorithm (SAMCRA), an improved and exact version of our QoS routing algorithm, the tunable accuracy multiple constraints routing algorithm (TAMCRA) we have investigated QoS routing in a hop-by-hop manner because it forms the basis of IP networking as e.g. in OSPF.

High-field hopping and ‘hopping domains’
Philosophical Magazine B, 2001Abstract The non-ohmic hopping conductivities of a large number of samples of lightly doped by various impurities (P. As, Sb, B and Ga) and weakly compensated n-and p-type Si were investigated. The current-voltage (I-V) characteristics appeared to be different in two temperature regions typical for the studies of Ohmic hopping conductivity: the low ...

Network coding for hop-by-hop communication enhancement in multi-hop networks
Computer Networks, 2016In our recent study, we introduced the PlayNCool protocol that increases thethroughput of the wireless networks by enabling a helper node to strengthenthe communication link between two neighboring nodes and using randomlinear network coding. This paper focuses on design and implementationadvantages of the PlayNCool protocol in a real environment of ...

Hop-by-Hop Beamforming for Dual-Hop MIMO AF Relay Networks
2011 IEEE International Conference on Communications (ICC), 2011A comprehensive performance analysis of dual-hop multiple-input multiple-output amplify-forward relay networks with hop-by-hop beamforming is presented. The impact of practical transmission impairments; (i) feedback delays, (ii) channel estimation errors and (iii) spatially-correlated fading on the system performance is studied.

Hop-by-Hop Frame Aggregation for VoIP on Multi-Hop Wireless Networks
2008 IEEE International Conference on Communications, 2008The already severe inefficiency problem in running VoIP on the IEEE 802.11-based wireless LAN is exacerbated in multi-hop networks due to spatial interference. This paper presents a novel scheme that significantly mitigates the effect of the interference by combining the inter-call aggregation and the pseudo-broadcast technique as used in network ...

Proceedings Sixth Heterogeneous Computing Workshop (HCW'97), 2002
We describe a novel framework for early detection and isolation of security violations in heterogeneous environments, based on real-time service hopping. In distributed client-server systems, service hopping fills a role analogous to frequency-hopping spread-spectrum techniques for secure wireless communication.

Evidence of Dextrin Hydrolyzing Enzymes in Cascade Hops ( Humulus lupulus).
Journal of Agricultural and Food Chemistry, 2018Dry-hopping, the addition of hops to beer during or after fermentation, is a common practice in brewing to impart hoppy flavor to beer. Previously assumed to be inert ingredients, recent evidence suggests that hops contain biologically active compounds ...

The American Mathematical Monthly, 1999
The dynamical behavior of a massless hoop with an attached point mass under the influence of gravity is an old chestnut, with some surprising features, including the question of whether or not it can "hop". It appears in Littlewood's Miscellany [1] and most recently in this MONTHLY [2].

Drug Discovery Today: Technologies, 2004
The aim of scaffold hopping is to discover structurally novel compounds starting from known active compounds by modifying the central core structure of the molecule. Scaffold hopping is a central task of modern medicinal chemistry requiring a multitude of techniques, which are discussed in this article.
