This book was released on 2017-08-18 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an in-depth discussion on how to efficiently manage resources of heterogeneous wireless networks and how to design resource allocation algorithms to suit real world conditions. Efficiently managing resources of the networks is more crucial now, than ever before, to meet users’ rapidly increasing demand for higher data rates, better quality-of-service (QoS) and seamless coverage. Some of the techniques that can be incorporated within heterogeneous wireless networks to achieve this objective are interworking of the networks, user multi-homing and device-to-device (D2D) communication. Designing resource allocation algorithms to suit real world conditions is also important, as the algorithms should be deployable and perform well in real networks. For example, two of the conditions considered in this book are resource allocation intervals of different networks are different and small cell base stations have limited computational capacity. To address the first condition, resource allocation algorithms for interworking systems are designed to allocate resources of different networks at different time-scales. To address the second condition, resource allocation algorithms are designed to be able to run at cloud computing servers. More of such conditions, algorithms designed to suit these conditions, modeling techniques for various networks and performance analysis of the algorithms are discussed in the book. This book concludes with a discussion on the future research directions on the related fields of study. Advanced-level students focused on communication and networking will use this book as a study guide. Researchers and experts in the fields of networking, converged networks, small-cell networks, resource management, and interference management, as well as consultants working in network planning and optimization and managers, executives and network architects working in the networking industry will also find this book useful as a reference.

Abstract: Abstract of the thesis entitled "Mobility and Radio Resource Management in Heterogeneous Wireless Networks" submitted by Xiaoshan Liu for the degree of Doctor of Philosophy at the University of Hong Kong in October 2006 Future generation wireless communication systems are characterized by ubiquitous access and Quality of Service (QoS) guarantees. They consist of IP-based heterogeneous wireless networks (HWN) with overlaid coverage to provide users with a broad range of access services. In a wireless communication system, mobility and radio resource management are essential system functions to support seamless global roaming. However, the functions in HWN systems are very different from those employed in traditional homogeneous wireless networks, and presents new challenges. First, the complexity and large dimension of an HWN system adds to the latency of signaling when signals traverse the component networks. When mobile users make handoffs in HWN, long handoff delay and heavy packet loss will be caused by this prolonged signaling exchange, seriously compromising QoS. Second, every component network is deployed following its own architecture and the characteristics of its particular technology. Therefore, the underlying radio resource management (RRM) functions need to be coordinated in admission control to improve users' experience and system performance. In this study, we propose methods in architecture, protocol and algorithms to solve the above problems in an HWN system. We first introduce a mobility management architecture with an Edge Mobility Agent (EMA) to improve the performance of handoffs between different networks. In the architecture, an EMA is introduced at the edge of the low-tier network to provide a transition area for handoff signaling exchange that effectively eliminates delay and packet loss during a vertical handoff. We also propose a Service Differentiated Handoff Protocol (SDHP) to handle handoffs between cells of the same network. In SDHP, we classify connections' QoS requirements into two classes and propose to use different handoff schemes to handle these connections to satisfy their different QoS requirements. With SDHP, we strike a balance between users' handoff experience and efficiency of radio resource utilization. To optimize radio resource utilization and access selection, we propose two joint admission control schemes to allocate connection requests to different component networks. In one scheme, the bandwidth to be allocated for each user is adaptive to the current resource utilization of every access network. A profit function is established to evaluate the profits gained from a handoff and the target network is selected accordingly. In another scheme, we formulate the joint admission control problem as a Semi- Markov Decision Process, and employ bandwidth adaptation to improve users' experience. We propose to use multi-agent system reinforcement learning to optimize SMDP. With this method, the system will learn an optimal policy from its experience that matches the characteristics of system capacity and user traffic, and maximizes a policy-based system reward. With the above proposals in architecture, protocol and algorithms, we provide a solution combining mobility and radio resource management and realize seamless global roaming with QoS support in HWN systems.

Book excerpt: Due to the great success and enormous impact of IP networks, In ternet access (such as sending and receiving e-mails) and web brows ing have become the ruling paradigm for next generation wireless systems. On the other hand, great technological and commercial success of services and applications is being witnessed in mobile wire less communications with examples of cellular, pes voice telephony and wireless LANs. The service paradigm has thus shifted from the conventional voice service to seamlessly integrated high quality mul timedia transmission over broadband wireless mobile networks. The multimedia content may include data, voice, audio, image, video and so on. With availability of more powerful portable devices, such as PDA, portable computer and cellular phone, coupled with the easier access to the core network (using a mobile device), the number of mobile users and the demand for multimedia-based applications is increasing rapidly. As a result, there is an urgent need for a sys tem that supports heterogeneous multimedia services and provides seamless access to the desired resources via wireless connections. Therefore, the convergence of multimedia communication and wireless mobile networking technologies into the next generation wireless multimedia (WMM) networks with the vision of "anytime, anywhere, anyform" information system is the certain trend in the foreseeable future. However, successful combination of these two technologies presents many challenges such as available spectral bandwidth, energy efficiency, seamless end-to-end communication, robustness, security, etc.

This book was released on 2008-09-18 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heterogeneous wireless networking, which is sometimes referred to as the fourth-generation (4G) wireless, is a new frontier in the future wireless communications technology and there has been a growing interest on this topic among researchers and engineers in both academia and industry. This book will include a set of research and survey articles featuring the recent advances in theory and applications of heterogeneous wireless networking technology for the next generation (e.g., fourth generation) wireless communications systems. With the rapid growth in the number of wireless applications, services and devices, using a single wireless technology such as a second generation (2G) and third generation (3G) wireless system would not be efficient to deliver high speed data rate and quality-of-service (QoS) support to mobile users in a seamless way. Fourth generation (4G) wireless systems are devised with the vision of heterogeneity in which a mobile user/device will be able to connect to multiple wireless networks (e.g., WLAN, cellular, WMAN) simultaneously. This book intends to provide a unified view on the state-of-the-art of protocols and architectures for heterogeneous wireless networking. The contributed articles will cover both the theoretical concepts and system-level implementation issues related to design, analysis, and optimization of architectures and protocols for heterogeneous wireless access networks.

This book was released on 2014-03-21 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SpringerBrief provides an in-depth look at the key issues that affect the performance of heterogeneous networks and presents schemes that can effectively tackle these issues. In particular, this book discusses unbalanced traffic load among the macro and micro Base Stations (BSs) caused by the transmit power disparity, and a load-balancing based mobile association scheme to balance the traffic load among the macro and micro BSs. This book also introduces a fractional frequency reuse (FFR) scheme with proper power control to help reduce interference at the UEs which are most vulnerable to such intra-cell interference. The last section investigates radio resource allocation issues for heterogeneous networks with cooperative relays, and proposes a resource allocation framework that could achieve proportional fairness among the UEs. Numerical results are provided to demonstrate the effectiveness of the proposed solutions in tackling the problem and improving network performance. Resource Management for Heterogeneous Networks in LTE-A Systems is designed for researchers and professionals working in networking and resource management. The content is also valuable for advanced-level students in computer science and electrical engineering.

Download or read book Radio Resource Management Strategies in UMTS written by Jordi Perez Romero and published by John Wiley & Sons. This book was released on 2005-10-31 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: The key feature of future mobile communication systems is the ability to deliver wideband and high bit-rate multimedia services alongside the traditional radio services such as voice, messaging and slow rate data. The broad range of services expected to be supported can be divided into different Quality of Service (QoS) classes. However, the provision of such mobile multimedia services under QoS guarantees will not be possible without a utilization of the air interface resources by means of Radio Resource Management (RRM) strategies that ensure the target QoS, the planned coverage area and that offer a high system capacity. Under this framework, the book focuses on the RRM concepts, including the theoretical background that serves as a basis for the description of specific RRM algorithms. The RRM problem for UMTS is presented, and more specifically, for the FDD mode, which is based on a WCDMA scheme. More specifically, the different aspects that are covered include: Introduces the mobile communications sector and UMTS, including the evolution towards 4G systems, with an overview of the QoS concept which is key for the definition of RRM strategies Offers a detailed description of the radio interface in UMTS, as the basis for the implementation of RRM strategies Provides the fundamental concepts related with the development of RRM strategies in WCDMA networks Analyses particular RRM algorithms in a variety of scenarios, trying to identify the key parameters and factors that influence their performance Explores the evolution of UMTS towards Beyond 3G systems and the concept of Common RRM in heterogeneous networks with the aid of some algorithm examples This comprehensive title is essential reading for engineers and managers in radio engineering departments of UMTS network operators and UMTS equipment manufacturers. It will also prove insightful to researchers in the field of 3G and Beyond 3G systems and academics in any of these areas.

Download or read book Radio Resource Management for Mobile Traffic Offloading in Heterogeneous Cellular Networks written by Yuan Wu and published by Springer. This book was released on 2017-01-03 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SpringerBrief offers two concrete design examples for traffic offloading. The first is an optimal resource allocation for small-cell based traffic offloading that aims at minimizing mobile users’ data cost. The second is an optimal resource allocation for device-to-device assisted traffic offloading that also minimizes the total energy consumption and cellular link usage (while providing an overview of the challenging issues). Both examples illustrate the importance of proper resource allocation to the success of traffic offloading, show the consequent performance advantages of executing optimal resource allocation, and present the methodologies to achieve the corresponding optimal offloading solution for traffic offloading in heterogeneous cellular networks. The authors also include an overview of heterogeneous cellular networks and explain different traffic offloading paradigms ranging from uplink traffic offloading through small cells to downlink traffic offloading via mobile device-to-device cooperation. This brief is an excellent resource for postgraduate students studying advanced-level topics in wireless communications and networking. Researchers, engineers and professionals working in related fields will also find this brief a valuable resource tool.
