Book Description
The convergence of the Internet and the multimedia communication will be expected in the next generation of mobile wireless networks. Supporting various applications with diverse traffic characteristics at an acceptable Quality of Service (QoS) is remaining a critical issue, especially in the mobile wireless environment. This book summarizes various networking technologies, architectures and mechanisms for QoS support. The author outlines the issues of QoS guarantees, presents key control mechanisms and enhanced techniques for QoS support and describes a general framework for QoS control mechanisms that can be used to evaluate and to develop mechanisms and architectures for providing QoS guarantees. This book gives a comprehensive view of key technologies, mechanisms and architectures and discusses various analytical techniques to help get the most out of network resources and to provide performance guarantees. Contents: Issues of Providing Quality of Service in the mobile wireless environments - Key mechanisms and architectures for Quality of Service support.

Book Description
QoS (Quality of Service) and Network Management are old topics. However, the fusion of IP style multimedia and wireless networks (3G) means that network managers who might previously have dealt with one or the other, must now manage and provide service guarantees for the both. This is where Managing Service Level Quality across Wireless and Fixed Networks steps in. It begins by examining the mechanisms that already existed in fixed IP data networks prior to the introduction of probe and agent technology. A look at these later developments is then supplemented with a real-world scenario of how real time application performance monitoring can not only provide service level management but can also aid in root cause analysis. This same model is then applied to a wireless environment examining which elements are required to be able to deliver multimedia services across 2nd and 3rd generation mobile networks, detailing the components of data networking that will assist in guaranteeing service level performance and the constraints placed on those guarantees when passing services over an air interface to a wireless-enabled device. It asks a simple question: will multimedia applications and the guaranteed levels of service required by them work when traversing from fixed to wireless networks? It tracks QoS components and mechanisms of both environments and looks at what will provide the glue in this brave new converged world and also provides empirical data to back up the conclusions drawn. First book available which applies QoS techniques and technologies to wireless/mobile networks 3G/UMTS Deals with the search for the real time information that constitutes the "customer experience" in terms of application performance so that service levels can be verified against measurable and relevant data in a true end-to-end manner across both fixed and wireless networks Presents probe and agent technology Features a real-world scenario of how real time application performance monitoring can not only provide service level management but can also aid in root cause analysis - this will be of particular interest to practitioner Analyses which elements are required in order to deliver multimedia services across 2nd and 3rd generation mobile networks Details the components of data networking that will assist in guaranteeing service level performance Essential reading for Wireless and IP data network professionals/practitioners, network managers and architects, technical consultants, quality assessment engineers, infrastructure vendors, application developers, portal designers, wireline operators, lecturers, postgraduates, senior undergraduate students and industry trainees.

Book Description
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.

Book Description
Provides extensive coverage of standardized QoS technologies for fixed and mobile ultra-broadband networks and services—bringing together technical, regulation, and business aspects The Quality of Service (QoS) has been mandatory for traditional telecommunication services such as telephony (voice) and television (TV) since the first half of the past century, however, with the convergence of telecommunication networks and services onto Internet technologies, the QoS provision remains a big challenge for all ICT services, not only for traditional ones. This book covers the standardized QoS technologies for fixed and mobile ultra-broadband networks and services, including the business aspects and QoS regulation framework, which all will have high impact on the ICTs in the current and the following decade. QoS for Fixed and Mobile Ultra-Broadband starts by introducing readers to the telecommunications field and the technology, and the many aspects of both QoS and QoE (Quality of Experience). The next chapter devotes itself to Internet QoS, starting with an overview of numerous technology protocols and finishing with business and regulatory aspects. The next three chapters look at QoS in NGN and Future Networks, QoS for fixed ultra-broadband, and QoS for mobile ultra-broadband. The book also provides readers with in-depth accounts of services in fixed and mobile ultra-broadband; broadband QoS parameters, KPIs, and measurements; network neutrality; and the QoS regulatory framework. Comprehensively covers every aspect of QoS technology for fixed and mobile ultra-broadband networks and services, including the technology, the many regulations, and their applications in business Explains how the QoS is transiting from the traditional telecom world to an all-IP world Presents all the fundamentals of QoS regulation, as well as SLA regulation QoS for Fixed and Mobile Ultra-Broadband is an excellent resource for managers, engineers, and employees from regulators, ICT government organizations, telecommunication companies (operators, service providers), ICT companies, and industry. It is also a good book for students and professors from academia who are interested in understanding, implementation, and regulation of QoS for fixed and mobile ultra-broadband.

Book Description
Overview and Goals Wireless communication technologies are undergoing rapid advancements. The past few years have experienced a steep growth in research in the area of wireless ad hoc networks. The attractiveness of ad hoc networks, in general, is attributed to their characteristics/features such as ability for infrastructure-less setup, minimal or no reliance on network planning and the ability of the nodes to self-organize and self-configure without the involvement of a centralized n- work manager, router, access point or a switch. These features help to set up a network fast in situations where there is no existing network setup or in times when setting up a fixed infrastructure network is considered infeasible, for example, in times of emergency or during relief operations. Even though ad hoc 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 scalability, quality-of-service, energy efficiency and security.
