This chapter discusses the most recent solutions for accelerating mobile data delivery, focusing on the different issues for achieving this goal. These issues include the efficiency of mobile data offloading and in-network caching. By characterizing different offloading options from the aspect offloading efficiency, dynamically offloading cellular traffic onto cost-effective options is able to achieve great performance gains. On the other hand, with concerns on tightly coupled dependency on original data sources, mobile users could easily suffer from the scarcity of content object resources. Researchers further account for the possibility of decoupling content availability dependency from original content sources. And a key enabling factor could be the recently emerged technology (i.e., in-network caching) whereby the emerging information-centric networking (ICN) performs its critical functionalities. Coupling ICN with mobile cellular network could be an attractive solution in order to resolve the tension between the tremendous growth of mobile content traffic and backhaul bottleneck.

5G mobile systems can be comprehended as highly flexible and programmable E2E networking infrastructures that provide increased performance in terms of capacity, latency, reliability, and energy efficiency while meeting a plethora of diverse requirements from multiple services. Network slicing is emerging as a prospective paradigm to meet these requirements with reduced operating cost and improved time and space functionality. A network slice is the way to provide better resource isolation and increased statistical multiplexing. With dynamic slicing, 5G will operate on flexible zone of the network, permitting varying, adaptable levels or bandwidth and reliability. In this chapter, a comprehensive survey of network slicing is presented from an E2E perspective, detailing its origination and current standardization efforts, principal concepts, enabling technologies, as well as applicable solutions. In particular, it provides specific slicing solutions for each part of the 5G systems, encompassing orchestration and management in the radio access and the core network domains.

The advent of heterogeneous broadband wireless access networks (BWANs) has been to support the ever-increasing cellular networks' data requirements by increasing capacity, spectrum efficiency, and network coverage. The focus of this chapter is to discuss the implementation details (i.e., architecture and network components), issues associated with heterogeneous BWANs (i.e., handovers, network selection, and base station placement), and also the various resource allocation schemes (i.e., shared resource allocation in split handover and inter-RAT self-organizing networks) that can improve the performance of the system by maximizing the network capacity.

Cooperative strategies amongst network players can improve network performance and spectrum utilization in future networking environments. Game Theory is very suitable for these emerging scenarios, since it models high-complex interactions among distributed decision makers. It also finds the more convenient management policies for the diverse players (e.g., content providers, cloud providers, edge providers, brokers, network providers, or users). These management policies optimize the performance of the overall network infrastructure with a fair utilization of their resources. This chapter discusses relevant theoretical models that enable cooperation amongst the players in distinct ways through, namely, pricing or reputation. In addition, the authors highlight open problems, such as the lack of proper models for dynamic and incomplete information scenarios. These upcoming scenarios are associated to computing and storage at the network edge, as well as, the deployment of large-scale IoT systems. The chapter finalizes by discussing a business model for future networks.

The increase in multimedia traffic is likely to pose challenges for the 5G networks. The data bundles are likely to increase but also open the door to new applications which will increase the data consumption. This chapter discusses how multimedia adaptation could be improved in this context by considering the user and the contextual factors for multimedia adaptation. This could be used to deliver a more accurate trade-off between quality and price. As a result, this could reduce the network consumptions, reduce the cost the user has to pay, and improve user satisfaction with the multimedia services.

The next generation of mobile wireless communications represents a heterogeneous environment which integrates variety of network generation like third generation (3G), fourth generation (4G), and fifth generation (5G). The major challenge in this heterogeneous environment is to decide which access point to use when multiple networks are available. Process of roaming mobile user from one technology to anther different is called vertical handover. In this chapter, the authors propose a new mechanism based on graph theory and cost function in order to determine the best path for the end user in terms of quality of service (QoS) when the vertical handover process is needed. Then, they investigate the impact of some existing weighting methods in order to determine the suitable method which can be coupled with the cost function. The experiments evaluation by using Mininet emulator demonstrate that the proposed approach can achieve a significant improvement concerning four QoS metrics: throughput, packet lost, packet delay, and packer jitter for two services FTP and video streaming.

With the emerging mobile applications and needs of ever-increasing bandwidth, it is anticipated that the next-generation passive optical network (NG-PON) with much higher bandwidth is a natural path forward to satisfy these demands and to develop valuable converged fiber-wireless access networks for wireless network operators. NG-PON systems present optical access infrastructures to support various applications of many service providers. Hybrid passive optical networks (HPON) present a necessary phase to future PON networks utilized the optical transmission medium – the optical fiber. For developing hybrid passive optical networks, there exist various architectures and directions. They are specified with emphasis on their basic characteristics. For proposing reliable and survivable architectures, traffic protection schemes must be implemented. For converging Fi-Wi passive optical networks, an integration of optical and wireless technologies into common broadband access network must be considered. Finally, the HPON network configurator as the interactive software tool is introduced.

With the rapid increase in data traffic and high data rate demands from cellular users, conventional cellular networks are becoming insufficient to fulfill these requirements. Femto cells are integrated in macro cellular network to increase the capacity, coverage, and to fulfill the increasing demands of the users. Time required for handoff process between the cells became more sensitive and complex with the introduction of femto cells in the network. Public internet which connect the femto base station with the mobile core network induces higher latency if conventional handoff procedures are also employed in macro-femto cell network. So, handoff process will become slower and network operation will become insufficient. Some standards, procedures, and protocols should be defined for macro-femto cell network rather than using existing protocols. This chapter presents a comprehensive survey of handoff process, types of handoff in macro-femto cell network, and proposed methods and schemes for frequent and unnecessary handoff reduction for efficient network operation.
