Available in PDF, EPUB and Kindle. Book excerpt: Next generation heterogeneous wireless networks are expected to interwork with Internet Protocol (IP)-based infrastructures. Conventional network services operate like silos in that a specific set of services are offered over a specific type of access network. As access networks evolve to provide IP-based packet access, it becomes attractive to break these "service silos" by offering a converged set of IP-based services to users who may access these services using a number of alternative access networks. This trend has started with third generation cellular mobile networks, which have standardized on the use of the IP Multimedia Subsystem (IMS) to manage user access to a wide variety of multimedia services over the mobile Internet, while facilitating interworking of heterogeneous wireless and landline access networks. The future users of communication systems will subscribe to both IP-based and Circuit Switched (CS) based services and in the foreseeable future a single database that handles user profiles across all domains will be required. Home Subscriber Server (HSS) as an evolved version of Home Location Register (HLR) is one of the key components of IMS. In deploying HSS as a central repository database, in a fully overlapped heterogeneous network setting, changes of access mode are very frequent and conveying this information to HSS imposes excessive signaling load and delay. In our proposed scheme we introduce an Interface Agent (IA) for each location area that caches the location and information about the access mode through which a user can be reached. This method results in significant amount of savings in signaling cost and better delay performance. The existing call delivery approaches in cellular networks may not be well suited for future communication systems because they suffer from unnecessary usage of network resources for call attempts that may fail which adds to excessive signaling delays and queuing costs. Reducing the number of queries and retrie.

Download or read book Resource Management for Heterogeneous Wireless Networks written by Amila Tharaperiya Gamage and published by Springer. 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.

Download or read book Efficient Resource Allocation and Network Design in Heterogeneous Wireless Networks written by Haiping Liu and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless networks provide flexible and ubiquitous access to the telephone networks or the Internet. Multiple technologies have been developed to provide wireless access including cellular/3G/LTE, WiFi, and WiMAX. The cellular network is the most popular network, which provides the stable and constant service under most types of mobility. Its future version, LTE Advanced, is the most advanced wireless access technology, and supports the current or future bandwidth-sensitive and/or delay-sensitive applications, such as Voice over IP and real-time video streaming. The WiFi network has been aggressively deployed in many areas and provide access to laptops, PDAs and smartphones. These are referred to as WiFi hotspots. The basic WiFi infrastructure usually offers flexible and easy to deploy wireless access inside a small area at a low cost. The WiMAX network has its own advantages to provide higher transmission speed for a point-to-point communication over longer transmission distances. In many areas, these wireless networks co-exist, overlap and interlace with one another to create a heterogeneous wireless network. Instead of functioning independently, significant benefits can be accrued through cooperation and coordination among these networks by leveraging their unique advantages. This is possible as user devices come with multiple network interfaces to connect to each of these networks. In order to exploit the advantages of these heterogeneous networks, it is important to implement an efficient resource allocation algorithm to coordinate the resources of multiple wireless networks and also have a good design of the heterogeneous network. The dissertation makes contributions in both the above areas. In current WiFi networks, the overall spectrum is divided among multiple overlapping channels. The adjacent access points need to operate on orthogonal channels to avoid the interference. In Chapter II, we give a precise analysis of the interference among different channels and discuss the potential possibility of utilizing partially overlapping channels in the multi-hop mesh networks. It is possible to optimize different network performance metric, such as throughput, by balancing parallel transmissions and partially received transmission power offers the best system performance, such as throughput. In the multi-hop mesh networks, some mesh nodes are highly congested either due to the interferences from multiple neighbors, or when they are located at the intersection of multiple routing paths. These highly congested mesh nodes significantly degrade the network performance, since the throughput of a path is limited by the node with minimum capacity. In Chapter III, we discuss the efficient cooperation between a WiFi-based mesh network and a WiMAX network to mitigate the impact of congested nodes. The WiMAX network, with its longer transmission range, can be leveraged to bypass the traffic from some highly congested mesh nodes. The load balancing makes the throughput of the heterogeneous network higher than the sum of the throughput from the WiFi and WiMAX networks if they operate independently. In the widely deployed wireless networks, the infrastructure mode is used, where customer devices only communicate with the base stations. This mode is suitable for normal Internet access. However, some emerging applications, such as P2P file sharing, teleconferencing, network games, require frequent communications among terminals that may be in the coverage of the same base station. The exiting infrastructure mode of the network architecture results in high resource waste due to the unnecessary transmissions via the base station even when both the user could directly communicate. In Chapter IV, we propose a novel network architecture, Local-Interest-Group (LIG), in which all nodes can communicate in any ways according to the application requirements. The real-time algorithm and protocol minimize the interferences among co-existing LIGs and maximize the bandwidth utilization, which greatly improves the overall system performance under multiple performance metrics. In network planning, it is difficult to efficiently locate base stations due to the inaccuracies in the prediction of the traffic density. The movement of traffic to different parts in the city during different times of a day makes fixed base stations either operate at very low load or become highly congested at different time periods. Fortunately, the detailed analysis based on network measurement shows that the movement of traffic density is predicable. In Chapter V, we propose a new network component, Traffic-Tracing Gateway (TTG), which works as the base station but traces the traffic movement taking the advantage of the heterogeneous wireless networks. By following the optimal trajectories, TTGs cover the maximum traffic and provide much better system performance in both single-hop or multi-hop networks. This dissertation proposes efficient resource allocation methods in heterogenous wireless access network with partially overlapping channels and the cooperation between WiFi and WiMAX networks. In the dissertation, we also propose the novel network designs based on local-interest-groups and traffic-tracing gateways, to augment existing wireless access networks and making them more resource efficient while providing higher end-to-end performance.

Book excerpt: Heterogeneous wireless networks (HWNs) provide flexible and diversified wireless network access (e.g., cellular, IEEE 802.11) by integrating cellular networks, wireless LANs, and ad hoc networks with the Internet. It has been emerging as a promising solution to offer a variety of exciting applications, anytime and anywhere. The flexibility and benefits of the HWN, for example, is to extend the service coverage of the existing cellular and WLAN infrastructure, to improve the communication throughput, and reduce packet transmission latency, based on availability of different types of radio network in the roaming area (cellular, WLAN, or others). In the study, we answer some fundamental questions in the design and deployment of a HWN. The first is how to effectively operate a mobile terminal in ad hoc mode to access the Internet through a cellular network, WLAN or other underlying wireless access networks. The second is how to design ubiquitous seamless mobility support for a roaming user, allowing ubiquitous and bi-directional Internet accessibility, connectivity, and mobility. Finally, it answers the questions that what is the security threats for a mobile terminal that is operating in the ad hoc mode, and how to provide information confidentiality for a continuously moving mobile terminal.
