<span lang="EN-US">In this research, approaches to making e-learning accessible to students with impairments were studied based on the authors’ experience at Jordan’s Al-Zaytoonah University. The educational, organizational, and instructional concerns are underlined when analyzing the university’s experience in giving access to online content. Furthermore, these difficulties must be addressed in order to create the necessary organizational change to effectively solve accessibility concerns. This study looked into the e-learning issues that 56 university students with disabilities had reported. Students reported issues with: accessibility to websites and learning course management systems; accessibility to digital audio and video; time management in completing online tasks; trouble handling data during lectures; and a lack of appropriate adaptive strategies in online questionnaires. Students also noted technical issues with using e-learning, instructors’ communication with e-learning, and their treatment of all students equally, overlooking the necessity of considering the needs of students with impairments. In this study, we present the problems raised by students with disabilities and how the e-learning affects students’ outcomes in the e-learning experience. We also make recommendations based on the students’ realistic special-needs experience at Al-Zaytoonah University in Jordan during the COVID-19 pandemic to inspire decision-makers in educational institutions and those interested in this field.</span>
A Wireless Sensor Network is a network of randomly deployed sensor nodes that cooperatively monitor the physical and environmental conditions. Such networks face some critical issues like limited battery power, limited network lifetime and deployment in drastic environmental conditions. The performance of Wireless Sensor Network largely depends on the routing protocols. The lifetime of the sensor network primarily depends on the residual battery of each sensor node. Many routing protocols have been proposed to optimize the energy efficiency of the Sensor Networks. We have carried out an extensive survey on WSN routing protocols. Clustering routing protocols out perform all other routing protocols in terms of extending the network lifetime. This paper mainly focuses on an in-depth survey of hierarchical or clustering routing protocols like LEACH and PEGASIS and their descendants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
