Sustainable Data-Driven Secured Optimization Using Dynamic Programming for Green Internet of Things.

The development of smart applications has benefited greatly from the expansion of wireless technologies. A range of tasks are performed, and end devices are made capable of communicating with one another with the support of artificial intelligence technology. The Internet of Things (IoT) increases the efficiency of communication networks due to its low costs and simple management. However, it has been demonstrated that many systems still need an intelligent strategy for green computing. Establishing reliable connectivity in Green-IoT (G-IoT) networks is another key research challenge. With the integration of edge computing, this study provides a Sustainable Data-driven Secured optimization model (SDS-GIoT) that uses dynamic programming to provide enhanced learning capabilities. First, the proposed approach examines multi-variable functions and delivers graph-based link predictions to locate the optimal nodes for edge networks. Moreover, it identifies a sub-path in multistage to continue data transfer if a route is unavailable due to certain communication circumstances. Second, while applying security, edge computing provides offloading services that lower the amount of processing power needed for low-constraint nodes. Finally, the SDS-GIoT model is verified with various experiments, and the performance results demonstrate its significance for a sustainable environment against existing solutions.

Mobile Phones in Classrooms and in Professor-Student Communication: Ukrainian, Omani, and U.S. American College Students’ Perceptions and Practices

<p>The unprecedented expansion of wireless technologies and the global pandemic of 2020-2021, which forced many educational establishments out of traditional face-to-face and into online instructional environments, have created an urgency for achieving a better understanding of the various education-related uses of mobile phones, and students’ attitudes toward them, worldwide. We conducted a questionnaire-based study to explore college undergraduate students’ perceptions and uses of mobile phones, with a focus on instructor-student communication and classroom use, across three diverse cultural contexts: Ukraine, Oman, and the United States. Based on our findings, we suggest that conceptualizing mobile phones as cultural tools and situating their use within cultural discourses illuminates how – and explains why – mobile phones are not “the same” tools for all students. The findings offer insights into students’ (developing) perspectives on uses of mobile phones, and provide grounds from which to formulate productive, and culturally appropriate, means of using them for educational purposes.</p><p> </p>

Use of Technology to Breathe New Life Into Chapter Meetings

Memberships at the Association of Women’s Health, Obstetric and Neonatal Nurses (AWHONN) span five generational age groups (the “silent generation,” baby boomers, Gen X, millennials, and Gen Z). Like many professional nursing organizations, in 2017 and 2018 AWHONN membership declined, which had a trickle-down effect on chapter meeting attendance. The North Central Illinois AWHONN chapter was reestablished in 2012. They had a very successful inaugural chapter meeting presentation with overwhelming attendance from both member and nonmember nurses in 2013. Since that first meeting, they have not been able to reproduce a large nursing attendance at their local meetings, that is, until the meeting held on October 18, 2017. The chapter members believe that the increase in attendance 2017 was a result of embracing technology by hosting their chapter’s first video conference meeting. Nurses seek greater flexibility in the ways they access and participate in learning. Time constraints, geographical boundaries, and travel costs have an impact on attendance at in-person meetings. In the search for a solution to their problem, the chapter leaders found that remote learning can provide nurses wider access to local AWHONN chapter learning opportunities. The expansion of wireless technology, in addition to advances in audiovisual technology and available software, helps support the delivery of video conference meeting presentations for the North Central Illinois AWHONN chapter. The North Central Illinois AWHONN chapter had a record number of participants on October 18, 2017 (32 in-seat and 17 virtual participants) and a repeat record number of participants on May 15, 2019 (12 in-seat and 35 virtual participants). On the basis of the positive conference evaluations that were received, the local chapter determined that their investment in technology supported this change. How do nurses who take care of women and newborns stay competitive as nurses? The right membership can provide nurses with new knowledge, improve their personal skills, gain recognition and personal fulfillment, protect their livelihood, and build connections with other nurses. This North Central Illinois AWHONN chapter is traveling full speed ahead on the Internet highway to maximize attendance for their chapter meetings and advance the mission of AWHONN.

Impossible meet-in-the-middle fault analysis on the LED lightweight cipher in VANETs

With the expansion of wireless technology, vehicular ad-hoc networks (VANETs) are emerging as a promising approach for realizing smart cities and addressing many serious traffic problems, such as road safety, convenience, and efficiency. To avoid any possible rancorous attacks, employing lightweight ciphers is most effective for implementing encryption/decryption, message authentication, and digital signatures for the security of the VANETs. Light encryption device (LED) is a lightweight block cipher with two basic keysize variants: LED-64 and LED-128. Since its inception, many fault analysis techniques have focused on provoking faults in the last four rounds to derive the 64-bit and 128-bit secret keys. It is vital to investigate whether injecting faults into a prior round enables breakage of the LED. This study presents a novel impossible meet-in-the-middle fault analysis on a prior round. A detailed analysis of the expected number of faults is used to uniquely determine the secret key. It is based on the propagation of truncated differentials and is surprisingly reminiscent of the computation of the complexity of a rectangle attack. It shows that the impossible meet-in-the-middle fault analysis could successfully break the LED by fault injections.

A Platform for Interactive Location-Based Services

The rapid expansion of wireless technologies and their interactions with wired networks together with wide spread of Global Navigation Satellite Systems (GNSS) infrastructures allow today the development of location-based services (LBS). Furthermore, the evolution of service oriented infrastructures enables information sharing between applications over the network. In this paper, a distributed interactive platform, called TransportML, for LBS interaction and cooperation is presented. It is an extended XML platform based on Services Oriented Architecture (SOA) principles to recognize, to monitor, and to collect service information and description over the network. A prototype is developed, in the context of intelligent transportation systems (ITS), to allow sharing information collected by each service and then acquiring more information about the driving context. This information helps drivers making appropriate decisions and, therefore, increases and improves road safety. The prototype is tested in urban and highway areas and results are reported to show the benefit of using this platform for sharing road information as well as services interaction.
