Existing optical and wireless networks designed to support today’s services may not be suitable for the emerging services, such as machine-to-machine applications of the Internet-of-Things paradigm and tactile-haptic applications of the Tactile Internet paradigm. Some of these applications must adhere to stringent quality of service requirements, especially an ultra-low end-to-end latency constraint of approximately 1 ms. In this paper, we investigate the feasibility of the wireless local area n...

The fifth generation (5G) wireless technology is designed to provide significantly faster Internet access, with lower latency, and ubiquitous mobile coverage compared to its predecessors. However, as there will be hundreds and thousands of wireless cells deployed in the 5G network, transporting the enormous volume of data instigated from high capacity 5G wireless cells to the core network in a cost-effective and greener manner with a low latency still remains one of the major hurdles. Therefore,...

The Internet has evolved a long way from transporting basic web data to transporting traffic instigated by new emerging applications that are available today. One such application is remote human-to-machine interaction, in which touch and actuation related information is delivered over the network. These applications are extremely sensitive to latency, with some reporting latency requirements in the millisecond range. Therefore, it is crucial to minimize latency experienced in each and every seg...

The Tactile Internet refers to the communication networks that have a closed control loop of tactile input and audio and/or visual feedback. Example applications include telerehabilitation and virtual training. To ensure that these applications have unnoticeable latencies and thus satisfied quality-of-service and quality-of-experience requirements, the Tactile Internet needs to guarantee round-trip latencies of approximately 1–10 ms. Such a stringent requirement cannot be met by today's technolo...

The development of the fifth generation (5G) wireless technology is in progress to address the increasing demands for high capacity, low latency, and ubiquitous mobile access instigated by next-generation mobile and machine-centric applications. The Centralized/Cloud-Radio Access Network (C-RAN) architecture exploiting the small-cell paradigm has been identified as a promising approach to address the benchmarks of 5G networks. However, providing a reliable, cost-effective, and quality of service...

The deployment of small cells has been identified as one of the future-proof solutions to cope with the increasing demand for higher data rate and ubiquitous access in mobile networks. However, providing a reliable and cost-effective backhaul connectivity for small cells has become a key challenge. It is identified that the cost efficiency of small-cell deployments can be improved by leveraging existing resources when planning the deployment. However, if not strategically planned the deployment,...

Optical---wireless convergence is becoming popular as one of the most efficient access network designs that provides quality of service (QoS) guaranteed, uninterrupted, and ubiquitous access to end users. The integration of passive optical networks (PONs) with next-generation wireless access networks is not only a promising integration option but also a cost-effective way of backhauling the next generation wireless access networks. The QoS performance of the PON---wireless converged network can ...

Today, video-on-demand (VoD) systems are challenged by a growing number of users, growing sizes of libraries, and increasing video streaming rates. Therefore, scalability and the bandwidth efficiency of VoD systems have become important considerations. In this paper, we propose a scalable and bandwidth efficient delivery scheme for VoD systems, which optimally exploits the storage and multicast capabilities to reduce the consumption of server capacity resources. Our proposed scheme, which we cal...
