"Vehicular ad-hoc network merupakan bagian dari MANET yang faktor pergerakannya dibatasi oleh jalan raya dan regulasi lalu lintas. VANET didukung dengan infrastruktur yang diam di satu titik yang dapat membantu dengan beberapa layanan dan juga untuk menghubungkannya jaringan stasioner dikarenakan faktor pergerakan node yang terbatas. Model mobilitas Manhattan merupakan salah satu model mobilitas untuk menggambarkan pergerakan mobile node dari VANET yang peta pergerakannya ditampilkan seperti model perkotaan Manhattan. Pada model ini terdapat algoritma traffic light model (TLM) yang berfungsi untuk mengatur pergerakan dari mobile node saat berada di persimpangan jalan raya. Penelitian dilakukan dengan menggunakan NS-2.34 sebagai pengatur pengiriman paket data dan VanetMobiSim 1.1 sebagai alat untuk menghasilkan model pergerakan dari model mobilitas Manhattan.
Dari hasil simulasi terlihat bahwa nilai end to end delay, dipengaruhi oleh padatnya node dalam suatu jaringan dan juga banyaknya rata-rata hop yang terbentuk dalam setiap rute. Dari segi rasio paket yang terkirim, nilai terbaik didapat pada jarak wireless 190m dengan nilai antara 90% - 99%. Dari segi rata-rata jumlah hop, nilai terbaik didapat pada jarak wireless 150m dengan rata-rata hop yang terbentuk antara 2.5 hingga 5 buah. Dari segi throughput, nilai terbaik didapat pada wireless range 190m dengan nilai maksimum mendekati 12 kbps untuk setiap tingkat kepadatan node.

Vehicular ad-hoc network is a part of MANET in which the movement factors must take into considerations the road topology and traffic regulations. VANET is supported with fixed infrastructure in a crucial points which can help with a few services, such as a warning messages. It also can connect the network to stationary network. The Manhattan mobility model is one of the mobility model that can generate the map pattern of Manhattan city, which resembles a complex traffic. In this model, there is a Traffic Light Model (TLM) algorithm that can control mobile node movement in intersection. In this work we study the implementation using NS-2.34 for an application to control the packet data sending, and VanetMobiSim 1.1 is used as an application to generate the movement model from Manhattan mobility model.
The simulation result shows that the end to end delay is depends on congestion of nodes, average hop in one route and congestion window. The results shows that Manhattan mobility model can reach 140 ms end to end delay on 190m wireless range. From packet delivery ratio Manhattan mobility model can reach score between 90% - 99% in 190m wireless range. The average hop is between 2.5 - 5 in 150m wireless range. Using this model, the throughput which can be achieved is up to 12 kbps.

"This book provides a comprehensive guide to the emerging field of network slicing and its importance to bringing novel 5G applications into fruition. The authors discuss the current trends, novel enabling technologies, and current challenges imposed on the cellular networks. Resource management aspects of network slicing are also discussed by summarizing and comparing traditional game theoretic and optimization based solutions. Finally, the book presents some use cases of network slicing and applications for vertical industries. Topics include 5G deliverables, Radio Access Network (RAN) resources, and Core Network (CN) resources. "

"This book paves the way for researchers working on the sustainable interdependent networks spread over the fields of computer science, electrical engineering, and smart infrastructures. It provides the readers with a comprehensive insight to understand an in-depth big picture of smart cities as a thorough example of interdependent large-scale networks in both theory and application aspects. The contributors specify the importance and position of the interdependent networks in the context of developing the sustainable smart cities and provide a comprehensive investigation of recently developed optimization methods for large-scale networks.
In the second volume of Sustainable Interdependent Networks book, the authors focus on the interdependencies of optimal operation of power and transportation networks; they discuss the optimization methods to deal with the computational complexity of them, and their role in future smart cities."

"The second edition of the book augments the first edition with more tricks, which have resulted from 14 years of theory and experimentation by some of the world's most prominent neural network researchers. These tricks can make a substantial difference (in terms of speed, ease of implementation, and accuracy) when it comes to putting algorithms to work on real problems.

"This book investigates the physical layer aspects of high-speed transmission on twisted-pair copper wires, where the most performance-critical components are multi-input multi-output (MIMO) precoding and multi-line spectrum optimization as well as optimized scheduling of the transmission time slots on the fiber to the distribution point (FTTdp) copper link. The book brings theoretical results into the implementation, which requires the introduction of realistic channel models and more practical implementation constraints as found in the copper access network.
A good understanding of the transmission medium, twisted-pair telephone cable bundles is the basis for this work. Starting from the analysis of measurement data from twisted-pair cable bundles at high frequencies, it presents a MIMO channel model for the FTTdp network, which allows the characteristic effects of high-frequency transmission on copper cable bundles in simulation to be reproduced and the physical layer transmission methods on the copper channels to be analyzed and optimize.
The book also presents precoding optimization for more general power constraints and implementation constraints. The maximization of data rate in a transmission system such as G.fast or VDSL is a combinatorial problem, as the rate is a discrete function of the number of modulated bits. Applying convex optimization methods to the problem offers an efficient and effective solution approach that is proven to operate close to the capacity of the FTTdp channel.
In addition to higher data rates, low power consumption is another important aspect of the FTTdp network, as it requires many access nodes that are supplied with power from the subscriber side over the twisted- pair copper wires. Discontinuous operation is a method of quickly adding and removing lines from the precoding group. To implement this, the system switches between different link configurations over time at a high frequency. The transmission times of all lines are jointly optimized with respect to the current rate requirements. Discontinuous operation is used to save power, but also makes it possible to further increase the data rates, taking the current subscriber traffic requirements into account. These methods are compared with theoretical upper bounds, using realistic channel models and conditions of a system implementation. The performance analysis provides deeper insights into implementation complexity trade-offs and the resulting gap to channel capacity."
