This work investigates the TCP-friendliness of a particular congestion control mechanism, TFRC, when it is employed to regulate the transmission rate of non-TCP sources competing for bandwidth with different TCP flavors (Reno, Sack and Westwood) flows in an IEEE 802.11b wireless LAN. Throughput of simultaneously active TFRC and TCP flows have been both experimentally measured and investigated t...

The aim of this study was to assess the dimensionality of YFHS-Swe and identify possible unique factors in the evaluation of youth-friendliness. YFHS-Swe was answered by 1110 youths aged 16 to 25 years visiting youth clinics in Northern Sweden. Thirteen factors were identified by exploratory factor analysis and except for one factor they all proved to fit well and have good reliability when ass...

A practical and green approach for the one-pot multicomponent synthesis of fused tetrazolo[1,5-a]quinazoline derivatives has been described via the condensation of 5- aminotetrazole, dimedone, and various aldehydes using 1-butyl-3-methylimidazolium tetrachloroaluminate [bmim]Cl/AlCl3, as a catalyst and task-specific ionic liquid medium. The catalyst was showed remarkable advantages in compariso...

In this paper, we propose a refinement of TCP Westwood allowing the management of the Efficiency/Friendliness-toNewReno tradeoff. We show that the refined TCP Westwood is able to achieve higher efficiency yet at the same time maintain friendliness. TCP Westwood (for short, TCPW) implements a novel window congestion control algorithm based on available bandwidth estimation. The performance of TC...

In the traditional express delivery sector, trucks are most available and efficient transportation mode in urban areas. However, due to pressures of traffic congestion air pollution problems, many cities have implemented strict measures restrict trucks’ access zones during specified time periods, which has caused significant effects on business industry. Due their advantages, include high speed...

The COVID-19 pandemic has caused the population to change their consumption behavior and habits a green living style protect environment. aim of this study was explore theory planned (TPB) model identify effect practices on willingness consume through customers’ emotional attachment, attitudes, satisfaction towards eco-friendly restaurants. We used quantitative method with self-administrated qu...

This demo presents a software tool whose aim is to quantify the level of network awareness and friendliness of the currently deployed Internet P2P applications. Considering such systems as black-boxes, we passively measure the traffic they generate and we gather, by means of both passive inference and active-probing techniques, some quantities relevant for their description. Observed metrics in...

Scalable TCP is a simple change to the traditional TCP congestion control algorithm which dramatically improves TCP performance in high speed wide area networks. The focus of this contribution is to model the performance of Scalable TCP algorithm sharing bottleneck link with a NewReno TCP. The analysis is performed during congestion avoidance phase, for both TCP flows, in steady state and near ...
