In this paper the speech recognition performance obtained when using Distributed Speech Recognition (DSR) architecture is compared to that obtained when the speech is first transcoded using the Adaptive Multi-Rate (AMR) speech codec at 4.75 and 12.2 kbps. In a like-versus-like comparison, made using the Advanced DSR Front-end and the Aurora reference back-end, the DSR architecture gives substan...

Hydrogenotrophic methanogenesis and dissimilatory sulfate reduction, two of the oldest energy conserving respiratory systems on Earth, apparently could not have evolved in the same host, as sulfite, an intermediate of sulfate reduction, inhibits methanogenesis. However, certain methanogenic archaea metabolize sulfite employing a deazaflavin cofactor (F(420))-dependent sulfite reductase (Fsr) wh...

Downward shortwave radiation (DSR) is an essential parameter in the terrestrial radiation budget and a necessary input for models of land-surface processes. Although several radiation products using satellite observations have been released, coarse spatial resolution and low accuracy limited their application. It is important to develop robust and accurate retrieval methods with higher spatial ...

In this work, we present the design of a mitigation scheme for jamming attacks integrated to the routing protocols MPH, AODV, and DSR. The resulting protocols are named MPH-M (Multi-Parent Hierarchical - Modified), AODV-M (Ad hoc On Demand Distance Vector - Modified), and DSR-M (Dynamic Source Routing - Modified). For the mitigation algorithm, if the detection algorithm running locally in each ...

Numerous studies have shown the difficulty for a routing protocol to scale to large wireless networks. Ad hoc routing protocols have to cope with an increasing node density and a significant number of nodes. DSR has been supported by the Manet working group as an IP routing protocol adapted to multi-hop wireless ad hoc networks [1,2]. DSR is a reactive source routing protocol. Source node provi...

This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited. Abstract This document specifies RTP payload formats for enca...

In this paper, virtual cell layout (VCL) based dynamic source routing (VB-DSR) technique is introduced for the mobile subsystem of the next generation tactical communications systems. VB-DSR uses dynamic source routing (DSR) protocol over VCL structure, which is a resource management and clustering technique for tactical communications. The application of the third generation personal communica...

A mobile ad hoc network is a self organizing temporary network. It consists of mobile nodes roaming here and there. Routing in such networks is a challenging task. Various routing protocols have been proposed since the origin of MANETS. DSR is the most popular routing protocol based on source routing. This paper is an extensive study of DSR taking various performance parameters. Effect of these...

Artefact evaluation is regarded as being crucial for Design Science Research (DSR) in order to rigorously proof an artefact’s relevance for practice. The availability of guidelines for structuring DSR processes notwithstanding, the current body of knowledge provides only rudimentary means for a design researcher to select and justify appropriate artefact evaluation strategies in a given situati...
