The Internet Of Things

Today, increasing Internet of Things devices are deployed, and the field of applications for decentralized, self-organizing networks keeps growing. The growth also makes these systems more attractive to attackers. Sybil attacks are a common issue, especially in decentralized networks and networks that are deployed in scenarios with irregular or unreliable Internet connectivity. The lack of a central authority that can be contacted at any time allows attackers to introduce arbitrary amounts of nodes into the network and manipulate its behavior according to the attacker’s goals, by posing as a majority participant. Depending on the structure of the network, employing Sybil node detection schemes may be difficult, and low powered Internet of Things devices are usually unable to perform impactful amounts of work for proof-of-work based schemes. In this paper, we present Rechained, a scheme that monetarily disincentivizes the creation of Sybil identities for networks that can operate with intermittent or no Internet connectivity. We introduce a new revocation mechanism for identities, tie them into the concepts of self-sovereign identities, and decentralized identifiers. Case-studies are used to discuss upper- and lower-bounds for the costs of Sybil identities and, therefore, the provided security level. Furthermore, we formalize the protocol using Colored Petri Nets to analyze its correctness and suitability. Proof-of-concept implementations are used to evaluate the performance of our scheme on low powered hardware as it might be found in Internet of Things applications.

Purpose The purpose of this study is to explore the characteristics and potential effects of teaching and learning through audio teleconferencing (dial-in) with a cell phone. In addition, the study aims to identify the associations between the audio teleconferencing and video teleconferencing in a 12-week postgraduate course. Design/methodology/approach The study is a cross-sectional survey conducted at the Department of Educational Innovations at the Kwame Nkrumah University of Science and Technology from March to June 2020. The purposive sampling technique was used to sample 100 postgraduate students who registered for a course in the department. The data for the study were collected using the System Usability Scale (SUS) and 17-item self-administered eQuestionnaire. Multiple Linear Regression analysis, ANOVA, Independent sample T-test and Mann–Whitney U-test were used to estimate the differences in course achievements of students who experienced education through audio teleconferencing and those who experienced education through video teleconferencing. Findings In total, 59% of the participating postgraduate students chose to attend the synchronous online lectures via audio teleconferencing (dial-in). The participants gave a high SUS score (SUS > 80.3; Grade A; Excellent) for audio conferencing service. Among the students in the audio teleconferencing cohort, the results evidenced a strong positive linear correlation, (r (57) = 0.79, p < 0.05), between the individual adjective ratings and the SUS scores. There was marginal significance among demography of students in the audio teleconference (AT) cohort with regards to their perception about the dial-in lecture. There was no statistically significant difference, (t (98) = 1.88, p = 0.063), in the achievement test for AT students and video teleconference (VT) students. The instructors and the students were satisfied with the AT. Practical implications Based on the students’ preference, AT offers equal benefit as VT with regards to system satisfaction and perceived quality of online teaching. AT, as teaching modality, should be an option for students who reside in communities with high latency internet connectivity. It is recommended that instructors are trained on how to engage and motivate students via AT. Originality/value Higher education institutions in Ghana are facing decisions about how to continue learning and teaching through flexible pedagogy, while keeping their faculty members and students protected from the COVID-19 pandemic. Many of these institutions have canceled the brick-and-mortar education and other conventional learning practices and have instructed faculty to adopt online teaching through synchronous video teleconferencing platforms. However, the learning experience is not the same for students who reside in remote or rural communities with low bandwidth. There is very little research in this topic, especially in developing countries like Ghana, and the present study aims to bridge the gap in the literature by exploring the characteristics and potential effects of teaching and learning through audio teleconferencing (dial-in) with a cell phone, in the context of a 12-week postgraduate course.

Access Service

The measuring of rendered services in any industry, especially in libraries, remains a critical tool to assess the satisfaction level of clients as well as the quality of the services. This article reports on a study that was undertaken to measure the quality of internet access service to South African public libraries by using the service quality model. The paper was guided by these objectives to identify the service quality models applicable to public libraries’ internet access; to determine how the quality of internet access service fits within the South African broadband policy; and to apply service quality dimensions to public libraries’ internet access. The study employed a quantitative approach and survey design in which a questionnaire was used to collect data from 322 heads of public libraries in South Africa. The stratified sampling method was used to obtain a proportional representation of public libraries. It emerged that most respondents regarded their internet service providers (ISPs) as incapable of solving their technical problems. It was further found that in most cases ISPs applied the internet access policies inconsistently to public libraries they served. The study recommended, among others, that internet connectivity to public libraries be centralised and that a competent provider be appointed to manage this service.

The Impact

In the current scenario quality control became mandatory for all the sectors .This study is intended to examine the impact of internet facilities on students’ performance through a Blended Learning as a medium in an academic institution. It was examined, how the Blended Learning encompasses a variety of tools to create flexible, rich learning environments that stimulate learners and maximizes the potential for learning? Another objective is Application of Six Sigma methodology in this study is to improve the medium of learning i.e. internet connectivity through a set of procedures in an effective way. Six Sigma can be again viewed as a discipline or an approach driven by data and methodology for eliminating defects in any process- from manufacturing to transactional and from product to service.Keeping the aforesaid two objectives in mind, data was collected from a sample of 119 students residing in various hostel blocks using stratified random sampling technique. Questionnaire was developed after an extensive literature review to measure the impact of internet connectivity in Blended Learning of the students. The questionnaire to measure was based on the model developed by Shawn M. Glynn (2011).The scale was developed by referring to previous models developed by various authors to measure the impact of internet connectivity in the Blended Learning of the students. The statistical analysis used was reliability statistics, KMO, Bartlett’s test and Factor Analysis. The data was analyzed by SPSS version 20). We observed that application of Six Sigma methodology is useful to improve the medium of learning.DOI: http://dx.doi.org/10.3126/ijssm.v2i1.11520     Int. J. Soc. Sci. Manage. Vol-2, issue-1: 36-39
