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.

具有触觉功能的以太网无源光医疗 LAN 中的高效资源分配

医疗保健环境的通信网络支持各种应用程序类型,并且应该能够在可靠的数据传输、可观的数据速率和低延迟方面为它们提供所需的服务质量 (QoS)。触觉互联网 (TI) 医疗保健应用程序的引入有望提升为患者提供的服务水平。这些应用程序的要求非常严格,一个主要要求是现有的网络基础设施必须支持它们。无源光网络 (PON) 已被提议作为支持此类苛刻环境的理想选择。此类网络的主要挑战之一是时域和波长域中的有效资源分配,这会显着影响所提供的 QoS。现有的 PON 资源分配算法的设计没有考虑 TI 应用的严格要求,从而使得 PON 对 TI 的支持效率低下。在本文中,提出了一种新的双优先级队列动态波长和带宽分配算法。该算法使用多种技术有效且公平地分配网络资源,以满足 Tactile 和其他类型的医疗保健应用程序的 QoS 需求。广泛的模拟结果表明,所提出的算法在各种模拟场景下为医疗应用提供所需的 QoS 的有效性,而其他众所周知的方案则缺乏这种支持。提出了一种新的双优先级队列动态波长和带宽分配算法。该算法使用多种技术有效且公平地分配网络资源,以满足 Tactile 和其他类型的医疗保健应用程序的 QoS 需求。广泛的模拟结果表明,所提出的算法在各种模拟场景下为医疗应用提供所需的 QoS 的有效性,而其他众所周知的方案则缺乏这种支持。提出了一种新的双优先级队列动态波长和带宽分配算法。该算法使用多种技术有效且公平地分配网络资源,以满足 Tactile 和其他类型的医疗保健应用程序的 QoS 需求。广泛的模拟结果表明,所提出的算法在各种模拟场景下为医疗应用提供所需的 QoS 的有效性,而其他众所周知的方案则缺乏这种支持。
