This work addresses the integration of today's infrastructure-based networks with infrastructure-less networks. The resulting Hybrid Routing System allows for communication over both network types and can help to overcome cost, communication, and overload problems. Mobility aspect resulting from infrastructure-less networks are analyzed and analytical models developed. For development and deployment of the Hybrid Routing System an overlay-based framework is presented.

With 5G, telecommunications networks have entered a new phase. 5G mobile networks use unique concepts and technologies to deliver current and future applications across a wide spectrum, from high bit-rate smartphones to high-availability car-to-x and mass IoT applications. This book on 5G technology starts with the evolution of mobile networks to 5G. It then addresses basic concepts and technologies such as NGN, IMS, virtualization with NFV and MEC, SDN, and Service Function Chaining. The 5G environment is comprehensively presented, starting with use cases and usage scenarios and moving on to concrete requirements, as well as the standardization at ITU and especially 3GPP, including regulation. In this context, the 5G system design, the 5G access networks with their high-performance transmission technology, and the core network with the innovative concepts of Service Based Architecture and Network Slicing play a significant role. A 5G system is presented here in an integrated view, rounded off by an overview of all relevant IT security aspects. The overall view is concluded by looking at the environmental influences of electromagnetic radiation and the energy and raw material resources requirements. Furthermore, the future development of 5G up to 6G is outlined. The book's main objective is to provide people interested in 5G technology and application scenarios with a well-founded knowledge for an introduction to 5G and encourage further discussion of this topic. The target audience is generally technically interested persons, mostly employees of public and private network operators. This book should be of particular interest, especially within the IT departments of potential 5G user companies, and of course, among computer science and electrical engineering students.

Anycast offers a method for making a service IP address available to a routing system from several locations at once. It is used today to provide important services, such as naming and content delivery, in an economic, scalable, and simple to operate manner. The appeal and clear benefits of anycast to service providers have motivated a number of recent experimental studies on its potential performance impact. All studies have, to the best of our knowledge, focused on wired networks, despite the growing dominance of mobile as the most common and sometimes only form of Internet access. In this paper, we present the first study of anycast performance for mobile users. In particular, our evaluation focuses on three distinct anycast services, K- and F-Root, each providing part the DNS root zone, and Google DNS. Our research revolves around three axes. First, we show that mobile clients are frequently routed to suboptimal replicas in terms of latency and that this issue is not limited to specific regions or ASes of the world. Second, we find that clients are often redirected to a DNS server hosted very far away from her. This happens more frequently while on a cellular connection than on WiFi, with a significant impact on performance. Our study reveals that this is not simply an issue of not having better alternatives, and that the problem is not localised to particular geographic areas or particular ASes. We investigate root causes of this phenomenon and describe three of the major detected classes of anycast anomalies. Third and finally, we explore IP assignment dynamics of mobile clients and find that recurrent IP changes on the client side lead to significant perceived variations of anycast latency.

The Second International Conference on Networks and Communications (NeCoM 2010), the Second International Conference on Wireless and Mobile Networks (WiMoN 2010), and the Second International Conference on Web and Semantic Technology (WeST 2010) were held in Chennai, India, during July 23–25, 2010. They attracted many local and int- national delegates, presenting a balanced mixture of intellects from the East and from the West. The goal of these conferences is to bring together researchers and practitioners from academia and industry to focus on understanding computer networks, wireless networks, mobile networks and the Web, semantic technologies and to establish new collaborations in these areas. Authors are invited to contribute to the conference by submitting articles that illustrate research results, projects, survey work and industrial experiences describing significant advances in the areas of all computer networks and Semantic Web technologies. The NeCoM 2010, WiMoN 2010 and WeST 2010 committees rigorously invited submissions for many months from researchers, scientists, engineers, students and practitioners related to the relevant themes and tracks of the workshop. This effort guaranteed submissions from an unparalleled number of internationally recognized top-level researchers. All the submissions underwent a strenuous peer-review process which comprised expert reviewers. These reviewers were selected from a talented pool of Technical Committee members and external reviewers on the basis of their expertise. The papers were then reviewed based on their contributions, technical c- tent, originality and clarity.
