With the increasing number of mobile subscribers worldwide, there is a need for fast and reliable algorithms for planning/optimization of mobile networks, especially because, in order to maintain a network’s quality of service, an operator might need to deploy more equipment. This paper presents a quick and reliable way to automatically plan a set of frequencies in a cellular network, using both cloud technologies and linear programming. We evaluate our pattern in a realistic scenario of a Global System for Mobile communications protocol (GSM) network and compare the results to another already implemented commercial tool. Results show that even though network quality was similar, our algorithm was twelve times faster and used four times less memory. It was also able to frequency plan seventy cells simultaneously in less than three minutes. This mechanism was successfully integrated in the professional tool Metric, and is currently being used for cellular planning. Its extension for application to 3/4/5G networks is under study.

The Mean

Transtelephonic electrocardiographic transmission (TET) is the most widespread form of telecardiology since it enables clinicians to assess patients at a distance. The purpose of this study was to assess the efficacy and effectiveness of TET either by fixed telephone line (POTS) or by mobile phone in the preparticipation screening of young athletes. A total of 506 players, aged 20.5 6.2 years, from 23 soccer clubs in the prefecture of Thessaloniki, Greece, were physically examined in their playfields by a general practitioner (GP) and had their ECG recorded. In 142 cases, and on the judgment of the GP, the ECG was transmitted via POTS and/or global system for mobile communications (GSM) to a specialised medical centre where it was evaluated by a cardiologist. The mean total time for recording, storing, and transmitting the ECG was four minutes per subject. It was found that the success rate for transmission at first attempt was similar for both fixed and mobile networks, that is, 93% and 91%, respectively. The failure rate in the GSM network was correlated to the reception level at the site of transmission. Only in about half ( = 74) of the transmitted ECGs did the cardiologist confirm “abnormal” findings, although in 16, they were considered to be clinically insignificant. Consequently, 58 athletes were referred for further medical examination. Our results indicate that TET (either by fixed telephone line or by mobile phone) can ensure valid, reliable, and objective measurements, and significantly contribute to the application of medical screening in a great number of athletes. Therefore, it is recommended as an alternative diagnostic tool for the preparticipation screening of athletes living in remote areas.

Global System for Mobile Communications (GSM) is a cellular network that is popular and has been growing in recent years. It was developed to solve fragmentation issues of the first cellular system, and it addresses digital modulation methods, level of the network structure, and services. It is fundamental for organizations to become learning organizations to keep up with the technology changes for network services to be at a competitive level. A simulation analysisusing the NetSim tool in this paper is presented for comparing different cellular network codecsfor GSM network performance. Theseparameters such as throughput, delay, and jitter are analyzed for the quality of service provided by each network codec. Unicast application for the cellular network is modeled for different network scenarios. Depending on the evaluation and simulation, it was discovered that G.711, GSM_FR, and GSM-EFR performed better than the other codecs, and they are considered to be the best codecs for cellular networks.These codecs will be of best use to better the performance of the network in the near future.

A Company

The satisfaction derived from services rendered by a company goes a long way in determining the response of consumers to these offerings and this can be either a positive or negative response. Hence, this study looks at customer’s purchase expectations and actions to GSM offerings in Ondo State. To achieve the objective above, this study employs a survey research design. A sample of 385 respondents was selected using multistage sampling, out of a population of about 906,557. The result confirmed that 85% of the GSM subscribers cannot guarantee adequate satisfaction with the quality of services with only one network, hence they use more than one network at the same time, switching over to the next each time they have the problem with one network. Secondly, the study finds that network accessibility has the highest customer’s expectations or satisfaction being met; followed by ease of obtaining call cards. Though tariff cost, network quality and bonus do not count much on expectation or satisfaction in Ondo State. Thirdly, both network accessibility and bonus have negative impacts on consumer perception of network quality but tariff cost, ease of obtaining cards, choice of the network have a positive impact on the perception of network quality. In conclusion, GSM companies need to be conscious of inconveniences encountered by their subscribers and they should do more to take care of those subscribers particularly in areas identified in this study. The study recommends that the companies should put preference on network accessibility to meet the customer expectations and that one of the ways to improve on GSM network quality is to educate consumers on their rights and privileges so that they can fight for their right. This should be championed by the supervising organ of government on GSM communication which is Nigeria Communication Commission (NCC).

Abrupt node movements is mobile networks directly affects the network connectivity of the node. Abruptly moving nodes generally face the issue of low network quality, and call drops. An effective handoff mechanism is needed in order to address this issue. In this research, we are proposing a network score based handoff mechanism, which follows the make-before-break principle. An improvement in terms of handoff delay, and packet loss is reported by the extensive analysis and simulations performed on the proposed system. Average handoff delay of less than 1ms, and packet loss ratio of less than 1% are obtained by our research. We plan to extend the research further for multiple networks to extend the performance analysis.

The report presents the author’s experience in integrating modern ICT technologies in the process of teaching and learning in school. The emphasis is on the use of mobile devices and the integration of cloud technologies in schools. As an ICT teacher, the author provides some practical guidelines on how to apply innovation. The generation of 7 screens does not know a world without digital technologies and mobile communications. The discrepancy between the expectations of the digital generation and the reality in our schools is in terms of the information and communication technologies (ICT) used in them and the didactic models. Adolescents, when they find themselves in an environment that does not meet their expectations, are demotivated and redirect their attention to other objects and goals and stop being active in class. The use of the so-called. „Cloud“ technologies will significantly increase the interest and retention of students. The modern approach to building information systems is focused on developing solutions in which the collection, input and output of information is carried out through WEB-based applications or platforms.

The evolution of Mobile Networks and Internet of Things (IoT) architectures allows one to rethink the way smart cities infrastructures are designed and managed, and solve a number of problems in terms of human mobility. The territories that adopt the sensoring era can take advantage of this disruptive technology to improve the quality of mobility of their citizens and the rationalization of their resources. However, with this rapid development of smart terminals and infrastructures, as well as the proliferation of diversified applications, even current networks may not be able to completely meet quickly rising human mobility demands. Thus, they are facing many challenges and to cope with these challenges, different standards and projects have been proposed so far. Accordingly, Artificial Intelligence (AI) has been utilized as a new paradigm for the design and optimization of mobile networks with a high level of intelligence. The objective of this work is to identify and discuss the challenges of mobile networks, alongside IoT and AI, to characterize smart human mobility and to discuss some workable solutions to these challenges. Finally, based on this discussion, we propose paths for future smart human mobility researches.

The Impact

Cloud Gaming is a cutting-edge paradigm in the video game provision where the graphics rendering and logic are computed in the cloud. This allows a user’s thin client systems with much more limited capabilities to offer a comparable experience with traditional local and online gaming but using reduced hardware requirements. In contrast, this approach stresses the communication networks between the client and the cloud. In this context, it is necessary to know how to configure the network in order to provide service with the best quality. To that end, the present work defines a novel framework for Cloud Gaming performance evaluation. This system is implemented in a real testbed and evaluates the Cloud Gaming approach for different transport networks (Ethernet, WiFi, and LTE (Long Term Evolution)) and scenarios, automating the acquisition of the gaming metrics. From this, the impact on the overall gaming experience is analyzed identifying the main parameters involved in its performance. Hence, the future lines for Cloud Gaming QoE-based (Quality of Experience) optimization are established, this way being of configuration, a trendy paradigm in the new-generation networks, such as 4G and 5G (Fourth and Fifth Generation of Mobile Networks).
