In a typical Ad Hoc network, mobile nodes have scarce shared band‐ width and limited battery life resources, so optimizing the resource and enhancing the overall network performance is the ultimate aim in such network. This paper proposes anew cross layer MAC algorithm called Location Based Transmission using a Neighbour Aware – Cross Layer MAC (LBT-NA Cross Layer MAC) that aims to reduce the t...

________________________________________________________________________________ Abstract Comparisons between production and breeding potential of different feeding systems (Concentrates, Mixed and Pastures) in South Africa were made. Data of active cows participating in performance testing as at November 2007 were used. Holstein cows numbered 68280 in 254 herds and Jersey cows 51275 in 248 her...

Human performance can degrade as a result of an increasing cognitive workload. Especially in domains in which good task performance is crucial these effects are unwanted, and hence, need to be avoided. In Psychological literature studies have been presented which relate a variety of measures to the workload experienced by humans. However, these experiments have not been conducted with more comp...

Performing an analysis of established software usually is challenging. Based on reverse engineering through dynamic analysis, it is possible to perform a software performance analysis, in order to detect performance bottlenecks or issues. This process is often divided into two consecutive tasks. The first task concerns monitoring the software, and the second task covers analysing and visualizin...

Nowadays, different mature IP-QoS standards and architectures for multimedia networking (e.g. Virtual Laboratory, E-Learning) are available for integration and testing in real scenarios. This article discusses the results of the end-to-end performance testing activity carried out over the European-wide MOICANE Project Pilot, a scalable GEANT-based network where the intelligence is concentrated ...

Effi cient web application is a challenge that we need to achieve when architecting web applications. This research follows a performance testing approach that aims to utilize load testing tools to give ideas about performance issues early in the development life cycle for applications implemented using Java Enterprise Edition (Java EE) or .NETplatform. Thus, it helps system architects to choos...

Traditional web applications are getting modernized to meet the expectations of customer demands. Various features like channels, infrastructure enhancements, cloud and big data adoptions, business analytics are getting implemented. This leads to complexity of the target application and also leads to difficulty in meeting the desired SLA. A tester can proactively identify issues by performing e...

Purpose – The primary purpose of this paper is to present a comprehensive strategy for performance, reliability and scalability (PSR) testing of multi-tier web applications. Design/methodology/approach – The strategy for PSR testing is presented primarily through examination of the intangible knowledge base in the PSR testing field. The paper also draws on relevant recent work conducted in the ...
