Hop-by-hop or longer hops: The energy perspective
2008 International Conference on Innovations in Information Technology, 2008We investigate, model and compare the expected energy consumption of routing over many short hops to the expected energy consumption of routing over longer hops. In addition to the common energy cost metrics of transmission and reception, our energy cost model also includes idle, noise, multi-path fading and retransmission energy costs.

Mechanisms of Hop Inhibition: Hop Ionophores
Journal of Agricultural and Food Chemistry, 2009In this work, the mechanism of hop inhibition toward (beer spoiling) bacteria is revised. The mode of action of iso-alpha-acids was investigated via bilayer lipid membrane (BLM) measurements and growth challenges of hop-sensitive and -resistant Lactobacillus brevis strains in the presence of uncouplers of class I and II or a H(+)/Mn(2+) exchanger.

2008 IEEE Asia-Pacific Services Computing Conference, 2008
In a MANET environment, communication links are unstable due to various reasons. Error rate is higher and bandwidth is smaller than fixed networks. Running conventional TCP protocol over MANET will suffer from severe performance degradation. To handle a packet loss, conventional TCP retransmits the lost packet from its source.

Hop by hop multicast routing protocol
Proceedings of the 2001 conference on Applications, technologies, architectures, and protocols for computer communications, 2001IP Multicast is facing a slow take-off although it is a hotly debated topic since more than a decade. Many reasons are responsible for this status. Hence, the Internet is likely to be organized with both unicast and multicast enabled networks. Thus, it is of utmost importance to design protocols that allow the progressive deployment of the multicast ...

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 ...
