"This monograph develops a framework for modeling and solving utility maximization problems in nonconvex wireless systems. The first part develops a model for utility optimization in wireless systems. The model is general enough to encompass a wide array of system configurations and performance objectives. Based on the general model, a set of methods for solving utility maximization problems is developed in the second part of the book. The development is based on a careful examination of the properties that are required for the application of each method. This part focuses on problems whose initial formulation does not allow for a solution by standard methods and discusses alternative approaches. The last part presents two case studies to demonstrate the application of the proposed framework. In both cases, utility maximization in multi-antenna broadcast channels is investigated."

"This SpringerBrief introduces the basics of wireless powered communication networks (WPCNs). In particular, the background and concept of WPCNs are briefly discussed. Moreover, this brief provides an extensive study of the recent developments in this area from an optimization perspective. Wireless powered communication network (WPCN) is a new network paradigm for IoT, where wireless devices (WDs) are powered by radio frequency (RF) based wireless power transfer (WPT) to eliminate the need for recharging or replacing the batteries manually and to prolong their lifetime.In this context, the brief also discusses some optimization problems for state-of-the-art scenarios of wireless powered communication networks.
The target audiences for this SpringerBrief are researchers, engineers, and undergraduate and graduate-level students, who are studying or working in wireless powered communication networks and its performance optimization."

"Salah satu tantangan utama dalam dunia telekomunikasi adalah menyediakan jasa Iayanan data berkecepatan tinggi. Kondisi keadaan pada saat ini, dengan teknologi broadband wireless yang ada dapat memberikan suatu cakupan area yang luas serta mampu dalam layanan data berkecepatan tinggi yang mengaplikaslkan multimedia.
Salah salu upaya untuk menyediakan jasa layanan data berkecepatan tinggi adalah dengan melakukan teknik diversitas Dimana dalam hal ini adalah teknik diversitas yang dilakukan adalah teknik divertisitas ruang (Space diversity technique).
Dalam tesis ini dilakukan simulasl teknik Space Time Block Coding (STBC) dan Space Frequency Block Coding (SFBC). Simulasi yang dilakukan adalah dengan memakai teknik pemancar tunggal clan pemancar ganda serta teknik penerima tunggal dan ganda.
Hasil pengujian menunjukkan bahwa teknik space time coding dan space frequency block coding dengan memakai teknik pemancar dan penerima ganda memiliki perfomansi yang balk dibandinkan memakai teknik pemancar tunggal penerima ganda atau sebaliknya.

One of the main challenge in telecommunication is to provide high speed data services. ln this recent condition, the broadband wireless technology could provide high scope coverage area and able to provide high speed data services using multimedia applications.
One of the efforts to proved high speed data services is to diversity technique, which means that we use space diversity technique.
ln this theses, we would use technique simulation space time block coding (STBC) and space frequency block coding (SFBC). ln this simulation we use single transmitter technique and multiple transmitter technique; we also use single receiver and multiple receiver technique.
This test result showed that using double transmitter and receiver technique in space time block coding technique and space frequency block coding will have a better performance compare to using single transmitter technique multiple receiver or on the contrary."

"Two of the fastest growing sectors of communications today are mobile and Internet, both of which have had a profound effect on people's lives. The convergence between these two sectors not only presents great opportunities for the future of 'unplugged' telecommunications, but also great challenges in understanding the relative position of different technologies in this future.
This book reviews the contribution of different wireless access technologies to that future and looks at the opportunities of opening up access to telecommunications systems, via application programming interfaces (APIs). The economic and regulatory issues associated with wireless communications are also discussed, with a look at the history and potential future of mobility from a user perspective."

"This book reviews the challenges of all-optical and wireless networks for the future Internet, with a focus on cross-layer design and optimization. Features : presents a thorough introduction to major networking modes and their effect on Internet development; proposes a new structure favorable for all-optical packet switching, discusses a new quality of service (QoS) provisioning approach, which overcomes the scalability problem of IntServ and the coarse QoS granularity of DiffServ, describes the end-to-end arguments in Internet design, before investigating a solution to congestion control problems in multi-hop wireless and all-optical networks, examines how to exploit multiple-input-multiple-output technology to improve network performance in centralized wireless networks, surveys green networking strategies from a quantitative perspective, suggests a strategic vision for possible developments of network technology for the future Internet."
