Efficient Resource Allocation in Tactile-Capable Ethernet Passive Optical Healthcare LANs

Abstract

Communication networks for healthcare environments support various application types and should be capable of providing them with the required Quality of Service (QoS) in terms of reliable data delivery, considerable data rate and low latency. The introduction of Tactile Internet (TI) healthcare applications is expected to upgrade the level of provided services to patients. The requirements of these applications are very stringent and a major requirement is that the existing network infrastructure must support them. Passive Optical Networks (PONs) have been proposed as an ideal candidate to support such demanding environments. One of the major challenges of such networks, which significantly affects the provided QoS, is the effective resource allocation in both the time and the wavelength domains. The existing resource allocation algorithms for PONs were designed without considering the stringent requirements of TI applications thus making PON support for TI inefficient. In this paper, a new double per priority queue dynamic wavelength and bandwidth allocation algorithm is presented. This algorithm allocates the network resources efficiently and fairly using several techniques, in order to meet the QoS demands of Tactile and other types of healthcare applications. Extensive simulation results indicate the effectiveness of the proposed algorithm to provide the required QoS for medical applications under various simulation scenarios whereas other well-known schemes are shown to lack such support.

QoS-Aware Multicast for Crowdsourced 360° Live Streaming in SDN Aided NG-EPON

“…The network traffic model for AF, TI and BE is based on self-similarity and longrange dependence. The recent studies in [39] have assumed that tactile internet traffic is Pareto distributed. This model will originate with high-burst AF, TI and BE traffic with a Hurst parameter of 0.…”

A Comprehensive Survey of the Tactile Internet: State-of-the-Art and Research Directions

“…Due to their high bandwidth and flexibility, PONs are promising candidates with which to realize low-latency Tactile Internet applications, especially for fixed users. Several algorithmic works [99] [106], [144]- [147] have studied the problem of scheduling and bandwidth allocation for PONs. In addition, [99] and [106] have suggested their PON-based network architectures for the Tactile Internet, as discussed in Section III.A.4 and Section III.B.6, respectively.…”

“…In addition, [99] and [106] have suggested their PON-based network architectures for the Tactile Internet, as discussed in Section III.A.4 and Section III.B.6, respectively. However, it should be noted that the PON-based network architectures considered in [99][106], [144]- [147] share a similar design concept. These network architectures mainly consist of multiple ONUs integrated with wireless APs to interact with This paper has been accepted for publication in IEEE Communications Surveys & Tutorials.…”

Recent Development of Flexible Tactile Sensors and Their Applications

“…With the recent further development of technology, tactile sensors are being studied for their application in medical devices and artificial intelligence beyond conventional touch screens or motion sensing applications [ 26 , 27 ]. Tactile sensors required in the medical field are used in pulse oscillators, breast cancer screening devices, measurement of pressure distribution in humans, and pressure mats for preventing ascites [ 28 , 29 , 30 ]. In the case of artificial intelligence, tactile sensors with high spatial resolution and performance, such as the fingertips of robots, are required [ 31 , 32 ].…”
