"Implementasi teknologi jaringan 5G pada suatu wilayah membutuhkan Capital Expenditure (CAPEX) dan Operational Expenses (OPEX) yang besar. Oleh karena itu, dibutuhkan teknologi network slicing, network function virtualization (NFV), dan software defined network (SDN) untuk menyediakan servis on-demand yang end-to-end. Network slicing memberikan kesempatan kepada operator-operator untuk membentuk NFV dengan Quality of Service (QoS) yang berbeda-beda dalam suatu sistem physical infrastructure network yang sama. Konfigurasi network slicing harus dilakukan dengan otomatis, aman, dan transparan sehingga diperlukan teknologi permissioned blockchain karena memiliki model distributed ledger dimana setiap komponen operator, regulator, ataupun vendor akan terhubung dalam suatu sistem jaringan 5G. Penelitian ini menggunakan Hyperledger Fabric untuk membangun Blockchain Network sesuai dengan arsitektur 5G dan konsep network slicing. Blockchain Network dibuat dengan enam channel dan algoritma konsensus Crash Fault Tolerance berbasis Raft. Penelitian ini menunjukkan bahwa telah dihasilkan sebuah Blockchain Network yang bisa menjalankan model network slicing berisikan empat organisasi yang saling terhubung satu sama lain. Hasil dari simulasi yang telah dilakukan menunjukkan bahwa terjadi pola peningkatan besar send rate (TPS) dan throughput (TPS) pada setiap penambahan jumlah client. = Implementing 5G network technology in an area requires high Capital Expenditure (CAPEX) and Operational Expenses (OPEX). Therefore, network slicing technology, Network Function Virtualization (NFV), and Software Defined Network (SDN) are needed to provide an end-to-end on-demand services. Network slicing provides an opportunity for operators to form NFVs with different Quality of Service (QoS) in the same physical infrastructure network system. Network slicing configuration must be done automatically, safely, and transparently so permissioned blockchain technology is needed because it has a distributed ledger model where each operator, regulator, or vendor component will be connected in a 5G network system. This research uses Hyperledger Fabric to build a Blockchain Network following the 5G architecture and network slicing concept. Blockchain Network is made with six channels and a Raft-based Crash Fault Tolerance consensus algorithm. This research shows that a Blockchain Network has been produced to run a network slicing model consisting of four organizations connected. The results of the simulations that have been carried out show an increasing pattern of send rate (TPS) and throughput (TPS) at each additional number of clients."

"As an extension of artificial intelligence research, artificial neural networks (ANN) aim to simulate intelligent behavior by mimicking the way that biological neural networks function. In Artificial Neural Networks, an international panel of experts report the history of the application of ANN to chemical and biological problems, provide a guide to network architectures, training and the extraction of rules from trained networks, and cover many cutting-edge examples of the application of ANN to chemistry and biology. In the tradition of the highly successful Methods in Molecular Biology series, this volume exhibits clear, easy-to-use information with many step-by-step laboratory protocols."

"This book presents comprehensive coverage of current and emerging multiple access, random access, and waveform design techniques for 5G wireless networks and beyond. A definitive reference for researchers in these fields, the book describes recent research from academia, industry, and standardization bodies. The book is an all-encompassing treatment of these areas addressing orthogonal multiple access and waveform design, non-orthogonal multiple access (NOMA) via power, code, and other domains, and orthogonal, non-orthogonal, and grant-free random access. The book builds its foundations on state of the art research papers, measurements, and experimental results from a variety of sources."

"ABSTRAKSetiap permintaan koneksi yang terjadi di jaringan seluler perlu melewati prosedur random access. Dalam jaringan 5G, terdapat minimal tiga layanan yaitu mMTC, eMBB, dan URLLC. Setiap layanan yang ada pada jaringan 5G dapat dibagi-bagi resource yang ada dengan menggunakan teknologi network slicing. Resource yang digunakan dalam prosedur random access yaitu preamble. Preamble dikonfigurasikan untuk setiap slice agar mencapai kebutuhan tiap layanan yang ada. Selain preamble, performa dari jaringan ditentukan oleh jumlah transmisi dan durasi backoff window, semakin besar kedua variabel tersebut maka jumlah perangkat yang dapat dilayani akan semakin banyak. Tetapi semakin banyak jumlah transmisi dapat menyebabkan borosnya daya yang dipakai dan semakin lama durasi backoff window menyebabkan delay yang tinggi. Pengaturan jumlah preamble, jumlah transmisi, dan lamanya backoff window pada masing-masing slice diperlukan untuk memenuhi kriteria yang diperlukan agar mendapatkan performa yang baik.

ABSTRACT

Every connection request that occurs on a cellular network needs to go through a random access procedure. In the 5G network, there are at least three services namely mMTC, eMBB, and URLLC. Every service on the 5G network can be shared with existing resources using network slicing technology. The used resource in the random access procedure is preamble. The preamble is configured for each slice to meet the needs of each existing service. Besides the preamble, the performance of the network is determined by the number of transmissions and the duration of the backoff window, the larger the two variables, the more devices can be served. But the greater number of transmissions can increase power usage and the longer duration of the backoff window causes a high delay. Setting the number of preambles, the number of transmissions, and the length of backoff window in each slice is needed to meet the criteria needed to get good performance.
