Development of Intelligent Core Network for Tactile Internet and Future Smart Systems

One of the main design aspects of the Tactile Internet system is the 1 ms end-to-end latency, which is considered as being the main challenge with the system realization. Forced by recent development and capabilities of the fifth generation (5G) cellular system, the Tactile Internet will become a real. One way to overcome the 1 ms latency is to employ a centralized controller in the core of the network with a global knowledge of the system, together with the concept of network function virtualization (NFV). This is the idea behind the software defined networking (SDN). This paper introduces a Tactile Internet system structure, which employs SDN in the core of the cellular network and mobile edge computing (MEC) in multi-levels. The work is mainly concerned with the structure of the core network. The system is simulated over a reliable environment and introduces a round trip latency of orders of 1 ms. This can be interpreted by the reduction of intermediate nodes that are involved in the communication process.

Multilevel cloud based Tactile Internet system

Far from the traditional Internet in which audio and visual senses can be transferred, the Tactile Internet will introduce a way for transferring touch and actuation in real time form. However, the fifth generation of the mobile cellular system (5G) will be a great support for realizing Tactile Internet, the 1 ms round-trip-delay still a great challenge in the way of the Tactile Internet realization. Mobile edge computing (MEC) is a solution introduced to reduce the round trip latency and provide a way for offloading computation from the cellular network. In this paper we introduce a novel approach toward a multi-level cloud based cellular system, in which the small cells are connected with micro-cloud units with small capabilities to present the edge computing facilities. The micro-clouds are connected to mini-cloud units which have greater capabilities. The core network cloud connects the mini-clouds in the whole system. Introducing more levels of clouding reduces the round trip latency and the network congestion.

System Model for Multi-level Cloud Based Tactile Internet System

With the realization of 5G system which will become a fact by 2020, there is a great demand to achieve the Tactile Internet system. Tactile Internet system should handle a 1 ms communication latency, which is the main problem of the system realization. One of the proposed system structures to achieve such latency is to build the system based on the multilevel cloud architecture and the 5G network structure. In this work, we build a system model for a multi-level cloud based Tactile Internet system. The model is used to find the system latency and evaluate the system performance. The proposed system is simulated and the results show that the system will achieve a lower latency than other known architectures. The proposed model also reduces the overall network congestion. It can be used to optimize the number of clouds in the system to achieve the best system performance.

IoT-fog based system structure with SDN enabled

IoT is a new communication paradigm that gains a very high importance in the past few years. Fog computing is a form of edge computing that is developed to provide the computing, storage and management capabilities near to users. Employing Fog computing in IoT networks as an intermediate layer between IoT devices and the remote cloud becomes a demand to make use of the edge computing benefits. In this work, we provide a framework for IoT system structure that employs an edge computing layer of Fog nodes. The system employs SDN network with a centralized controller and distributed OpenFlow switches; these switches are enabled with limited computing and processing capabilities. The network is operated based on a data offloading algorithm, that allocates certain processing and computing tasks to some OpenFlow switches that has unused resources. The proposed work achieves various benefits to the IoT network such as the latency reduction and higher efficiency of resources utilization. We perform an experiment over a developed testbed to validate the proposed system and results show that the proposed system achieves higher efficiency in terms of latency and resource utilization.

Key solutions for light limitations: toward tactile internet system realization

Enabling haptic communication as well as voice and data over the future 5G cellular system become a demand. Tactile Internet is one of the main use cases of the 5G system that will allow the transfer of haptic communications in real time. The end-to-end latency of 1ms remain the main challenge toward the Tactile Internet system realization, not only for the processing and coding delays but mainly for the limitations of light. In this work, we analyze the key solutions to overcome the light limitations and enable the Tactile Internet over any distances with the required latency. Building a virtual model or model mediated for the remote environment at the edge cloud unit near to the end user is the main solution. By means of AI the virtual model can predict the behavior of the remote environment and thus the end user can interact with the virtual environment with a high system experience. We review the exiting work for the model mediated bilateral systems and discuss its availability for the Tactile Internet system. Finally, we suggest a structure for the Tactile Internet system with the deployment of model mediated.

Multi-level Cluster Based Device-to-Device (D2D) Communication Protocol for the Base Station Failure Situation.

With the massive increase of wireless devices and the challenges associated, device-to-device (D2D) communication becomes a vital solution. Employing D2D communication achieves higher throughput, better cell coverage, increases the spectrum efficiency and other valuable benefits for the cellular networks. In this paper, D2D communication is used to overcome the problems occurred in the situation of Base station (BS) failure and maintain the communication inside the cell without BS. An energy efficient multi-level cluster based D2D communication protocol is introduced to maintain the cell operation even if the Base station is out of use. The protocol employs D2D communication and multi-level clustering to provide communication paths through the neighbouring cells and BSs. The proposed work also efficient if there is a catastrophic situation.
