In MIMO system, it is known that Multi-user diversity can be used to increase the sum system throughput. The maximization of the throughput under quality of service (QoS) constraints is a still open field for research. In this paper, a scheduling algorithm that uses fairness among users as a QoS constraint is considered. This algorithm, called Adaptive Proportionality Opportunistic Scheduling (...

Transmission Control Protocol (TCP) is a reliable, end-to-end transport protocol, which is most widely used for data services and is very efficient for wired networks. However, experiments and research showed that TCP's congestion control algorithm performs very poorly over Wireless Ad Hoc Networks with degraded throughputs and severe unfairness among flows. In this paper, a deep study has...

La crise du COVID-19 a exercé des contraintes sans précédent sur la capacité pouvoirs publics et contribuables à mener activités normales. Les procédures internationales d'allégement de retenue source, souvent tributaires processus manuels reposant l’utilisation documents papier, ont été particulièrement affectées, occasionnant difficultés pour les contribuables, institutions financières a...

This paper proposes GENCOs' profit maximization using Binary Article Bee Colony Optimization based on global best parameters (GbBABC). The optimal rival bidding strategy is employed to maximize GENCOs' profit. Monte Carlo (MC) simulation has been used to predict the bidding behavior of the rivals. In this paper, a bi-level optimization problem has been proposed to obtain the optimal b...

Academic research and engineering challenge both require high performance computing (HPC), which can be achieved through parallel programming. The existing curricula of most universities do not properly address the major transition from single-core to multicore systems and sequential to parallel programming. They focus on applying application program interface (API) libraries and open multiproc...

Recently digital forensics has become a prominent activity in crime investigation since computers are increasingly used as tools to commit crimes. During forensic investigation the digital devices such as desktops, notebooks, smart phones etc. found at the crime scene are collected for further investigation. Investigators have to go through humongous amount of data stored on these devices to ga...

In the mobile robot navigation, the ultrasonic sensors have been widely used for the obstacles detection and map building because of its cost and efficiency. Generally sensors are used to increase the accuracy of the obstacles position and decrease the time. In this paper an ultrasonic sensor is interfaced on to a stepper motor which will be constantly revolving and detecting the values of any ...

This paper presents a new approach to develop the strategy of Model–View–Controller architecture pattern in Business Intelligence (BI) architecture. The Business Intelligence architecture consists of the ETL tools and processes, the data warehouse, the technical infrastructure, and the user-interface tools. The major issue related to Business Intelligence architecture is to store the data from ...
