Book Synopsis LTE-A Cellular Networks by : Abid Yahya
Download or read book LTE-A Cellular Networks written by Abid Yahya and published by Springer. This book was released on 2016-09-02 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, three different methods are presented to enhance the capacity and coverage area in LTE-A cellular networks. The scope involves the evaluation of the effect of the RN location in terms of capacity and the determination of the optimum location of the relay that provides maximum achievable data rate for users with limited interference at the cell boundaries. This book presents a new model to enhance both capacity and coverage area in LTE-A cellular network by determining the optimum location for the RN with limited interference. The new model is designed to enhance the capacity of the relay link by employing two antennas in RN. This design enables the relay link to absorb more users at cell edge regions. An algorithm called the Balance Power Algorithm (BPA) is developed to reduce MR power consumption. The book pertains to postgraduate students and researchers in wireless & mobile communications.
Book Synopsis Analysis and Design of Communication Techniques in Spectrally Efficient Wireless Relaying Systems by : Jian Zhao
Download or read book Analysis and Design of Communication Techniques in Spectrally Efficient Wireless Relaying Systems written by Jian Zhao and published by Logos Verlag Berlin GmbH. This book was released on 2010 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation studies the communication technologies in relaying systems with multiple antennas, especially in the multiple-input multiple-output (MIMO) two-way relaying systems. Both information-theoretic aspects and practical communication strategies are considered and analyzed. For the information-theoretic analysis, an analytical framework for the coverage of MIMO relaying systems based on an outage capacity criterion is proposed. For MIMO two-way relaying systems, different data combining schemes at the relay are compared based on their achievable rates. In addition, optimal time-division (TD) strategies for MIMO two-way decode-and-forward (DF) relaying systems are proposed and analyzed. When the optimal TD strategies are applied, the increase of the achievable rate regions in the system is significant compared to those using the equal TD strategy. For the practical transmission schemes, we propose the self-interference (SI) aided channel estimation and data detection schemes for the broadcast phase of two-way DF relaying systems. Such schemes exploit the SI in two-way DF relaying systems when the superposition coding (SPC) scheme is applied. When the network coding scheme is applied in two-way DF relaying systems, we propose an asymmetric data rate transmission scheme that utilizes the known data bits at the receivers. Such a scheme exploits the a priori known bits at the weak link receiver in the broadcast phase of two-way relaying systems.

Download or read book Guide to Wireless Sensor Networks written by Sudip Misra and published by Springer Science & Business Media. This book was released on 2009-05-29 with total page 725 pages. Available in PDF, EPUB and Kindle. Book excerpt: Overview and Goals Wireless communication technologies are undergoing rapid advancements. The last few years have experienced a steep growth in research in the area of wireless sensor networks (WSNs). In WSNs, communication takes place with the help of spatially distributedautonomoussensornodesequippedtosensespeci?cinformation. WSNs, especially the ones that have gained much popularity in the recent years, are, ty- cally, ad hoc in nature and they inherit many characteristics/features of wireless ad hoc networks such as the ability for infrastructure-less setup, minimal or no reliance on network planning, and the ability of the nodes to self-organize and self-con?gure without the involvement of a centralized network manager, router, access point, or a switch. These features help to set up WSNs fast in situations where there is no existing network setup or in times when setting up a ?xed infrastructure network is considered infeasible, for example, in times of emergency or during relief - erations. WSNs ?nd a variety of applications in both the military and the civilian population worldwide such as in cases of enemy intrusion in the battle?eld, object tracking, habitat monitoring, patient monitoring, ?re detection, and so on. Even though sensor networks have emerged to be attractive and they hold great promises for our future, there are several challenges that need to be addressed. Some of the well-known challenges are attributed to issues relating to coverage and deployment, scalability, quality-of-service, size, computational power, energy ef?ciency, and security.

Book Synopsis Wireless and Mobile Networking by : Jozef Wozniak
Download or read book Wireless and Mobile Networking written by Jozef Wozniak and published by Springer. This book was released on 2009-08-31 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent spectacular achievements in wireless, mobile, and sensor networks have dramatically changed our lives in many ways. However, the rapid evolution of wireless systems not only promises increased functionality, reliability, availability, and security, as well as putting a wide variety of new services at the users’ disposal ? it also creates a number of design challenges that our research community is now facing. Scientists and engineers need to come up with, and promptly implement, novel wireless network architectures, while system operators and planners rethink their business models and attend to the growing expectations of their customer base. To provide a suitable forum for discussion between researchers, practitioners, and industry representatives interested in new developments in the respective research area, IFIP WG 6. 8 launched three separate series of conferences: MWCN (Mobile and Wireless Communications Networks), PWC (Personal Wireless Communications), and WSAN (Wireless Sensor and Actors Networks). In 2008, MWCN and PWC were merged into the IFIP Wireless and Mobile Networking Conference (WMNC 2008), held in Toulouse, France, from September 30 to October 2, 2008. MWNC 2008 and PWC 2008 topics were subsequently revised with a view to covering the whole spectrum of hot issues in wireless and mobile networking. As a result, IFIP WG 6. 8 decided to add WSAN as another WMNC track.
Book Synopsis Future Mobile Communication by : Raphael T. L. Rolny
Download or read book Future Mobile Communication written by Raphael T. L. Rolny and published by Logos Verlag Berlin GmbH. This book was released on 2016-03-31 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing demand for ubiquitous data service sets high expectations on future cellular networks. They should not only provide data rates that are higher by orders of magnitude than today's systems, but also have to guarantee high coverage and reliability. Thereby, sophisticated interference management is inevitable. The focus of this work is to develop cooperative transmission schemes that can be applied to cellular networks of the next generation and beyond. For this, conventional network architectures and communication protocols have to be challenged and new concepts need to be developed. Starting from cellular networks with base station cooperation, this thesis investigates how classical network architectures can evolve to future networks in which the mobile stations are no longer served by base stations in their close vicinity, but by a dynamic and flexible heterogeneity of different nodes. With the transition from classical cell-based networks to relay enabled post-cellular networks, we trade off node complexity with density. Aggressive spatial multiplexing can thereby deliver high data rates to large areas in a very efficient way, even when the backhaul capacity is limited or when in certain areas no backhaul access is available at all. The beneficial performance scaling shows that such post-cellular networks can offer a flexible and dynamic solution for mobile communication of future generations.
