The Internet of Things (IoT) smart city initiative has transformed technology spectrum into its new era of development. The increasing amount of data generated by millions of IoT devices and the rapid flow of data across distributed IoT devices are transmitting to remotely located cloud infrastructure over the Internet. Unfortunately, these large amounts of data and its flow based on the traditional energy-intensive network infrastructure is neither efficient nor substantially scalable. It is essential to design a comprehensive network infrastructure to handle large amount of high-speed data-processing in an IoT spectrum. Apparently, Blockchain and Software-Defined Networking (SDN) approaches can leveraged the scalability of the environment for IoT spectrum. In addition, the emergence of distributed cloud technology and Li-Fi spectrum can transform the capability of data-processing for IoT devices. The challenge lies in efficiently blend the integration of Li-Fi, Blockchain, SDN and Cloud technologies for IoT environment. To address this challenge, we design a multiaccess communication modulation model for efficient optimization of distributed network with an SDN based controller and integration of robust cloud infrastructure for high-speed data-processing. The proposed model is based on Li-Fi communication architecture which significantly reduced in the utilization of energy for managing large-scale infrastructure. We performed simulation and analysis across multiple dimensions to evaluate the performance and effectiveness of our proposed model. The evaluated output shows that our model significantly improved the overall performance and efficiency of the communication infrastructure as compared with other ultra-modern models.

Pada masa modern seperti ini kebutuhan akan internet semakin meningkat tajam, baik itu untuk bekerja mengolah data dan hiburan. Untuk membangun infrastruktur jaringan yang baik tentunya dibutuhkan penanganan yang tepat sesuai dengan kondisi di lapangan. Dalam penelitian ini kami mengangkat tema penerapan metode HTB yang akan diimplementasikan dalam jaringan RT/RW Net di Farid.net. Dalam analisa jaringan ini terdapat suatu masalah, setelah pengelompokan data dari pelanggan dimana terdapat keluhan tentang bandwidth yang didapat tidak sesuai dengan paket yang dipilih, sehingga hal tersebut menimbulkan ketidaknyamanan pengguna. Untuk mengatasi masalah tersebut kami mendapatkan solusi dengan menerapkan metode HTB. Cara kerja dari metode ini sendiri, membagi bandwidth kedalam beberapa kelas, yang mana terdapat dua kelas utama yaitu parent dan child, metode ini memungkinkan administrator untuk membagi bandwidth berdasarkan besar bandwidth yang diminta pelanggan. Dari penerapan metode HTB dapat diambil kesimpulan bahwa bandwidth yang didapat antar user menjadi lebih stabil dan merata, hal tersebut dapat dibuktikan dengan melalui Speedtest dan pemantauan traffic. Selain itu konektivitas jaringan pun juga lebih stabil dikarenakan bandwidth dari client sudah terkontrol.Kata Kunci — bandwidth, Hierarchical Token bandwidth, HTB.In modern times like this the need for the internet is increasing sharply, both for working on data processing and entertainment. To build a good network infrastructure, of course, proper handling is needed according to the conditions in the field. In this study we raise the theme of applying the HTB method which will be implemented in the RT / RW Net network at Farid.net. In this network analysis there is a problem, after grouping data from customers where there are complaints about the bandwidth obtained that is not in accordance with the package chosen, so that it causes user inconvenience. To overcome this problem, we got a solution by applying the HTB method. The workings of this method itself, dividing bandwidth into several classes, where there are two main classes, namely parent and child, this method allows the administrator to divide the bandwidth based on the bandwidth requested by the customer. From the application of the HTB method, it can be concluded that the bandwidth obtained between users becomes more stable and equitable, this can be proven by Speedtest and traffic monitoring. In addition, network connectivity is also more stable because the bandwidth of the client is controlled.Keywords — bandwidth, Hierarchical Token bandwidth, HTB.

Abstract. Background: Several studies found a significant relationship between important sport events and suicidal behavior. Aims: We set out to investigate whether there is a significant relationship between the raw suicide rate and the most important international sports events (Olympic Games, FIFA World Cup, UEFA European Championship) in such an achievement-oriented society as the Hungarian one, where these sport events receive great attention. Method: We examined suicide cases occurring over 15,706 days between January 1, 1970, and December 31, 2012 (43 years), separately for each gender. Because of the age-specific characteristics of suicide, the effects of these sport events were analyzed for the middle-aged (30–59 years old) and the elderly (over 60 years old) generations as well as for gender-specific population groups. The role of international sport events was examined with the help of time-series intervention analysis after cyclical and seasonal components were removed. Intervention analysis was based on the ARIMA model. Results: Our results showed that only the Olympic Games had a significant effect in the middle-aged population. Neither in the older male nor in any of the female age groups was a relationship between suicide and Olympic Games detected. Conclusion: The Olympic Games seem to decrease the rate of suicide among middle-aged men, slightly but significantly.
