A Study of QoS in an Integrated Architecture of WLAN and Hetnet Based LTE-A

In this paper, an integration architecture based on loose coupling concept between WiFi and LTE heterogeneous networks (HetNet) was proposed. The ultimate objective is to investigate the feasibility and the practicality of the design through investigating the performance measures for different applications in the network. As well, a functionality of the load balancing was deployed in the architecture in order to prove that the architecture is flexible and can be opened to any further functionality. The architecture was built and simulated using riverbed network simulator. It was proved that the architecture is working appropriately, and the connectivity of the different technologies were demonstrated by applications communication with each other’s in the architecture. Along with, different existing load balancer algorithms were tested on the architecture and numerical results were obtained demonstrating that algorithm is better

Teacher’s Perspective on The Challenges of Using ICT in Teaching: A Case Study in Education Faculty

Over the last decade, the rapid development of the technology has become a significant interest in Education. Information and Communication Technology (ICT) has integrated into learning and teaching along with delivering more chances for students and teachers to operate better in teaching and learning. Conversely, the obstacles may prevent teachers from applying ICT in the classroom. Analyzing the barriers of ICT integration can help and encourage educators to be creative and try to use a new approach for integrating technology into their everyday teaching process. This study investigates teachers’ perspectives on those obstacles for integrating ICT in teaching at the university level. It also aims to find out other uncommon barriers in teaching that any facilitators who are applying ICT can face. Sixty-seven participants from different positions and departments in the education field, who integrate ICT have participated in the study. A mixed method has been implemented. The data was collected through a survey with Google form. The quantitative data were analyzed by IBM SPSS version 28, while the thematic analysis was used for qualitative data. The study’s results have declared that most of the teachers have solid demand to apply ICT in teaching, even with these barriers. The most difficulties were internet connection and electricity in the process. It also indicated that ICT makes the class more effective through student engagement, time management, and student-student interactions
