Abstract
Healthcare applications are life-critical and the network infrastructure should be able to provide them the required Quality of Service (QoS) in terms of reliable data delivery, considerable data rate, and low latency. Tactile Internet medical applications are expected to upgrade the capabilities which medical experts can provide to patients. The requirements of such applications which include telediagnosis, telesurgery, and telerehabilitation are very stringent and Passive
Optical Networks (PONs) have been proposed as an ideal candidate to support such demanding environments. The effective resource allocation in both time and wavelength domains is a crucial factor in order to preserve the provided QoS. In this paper, a new Double per Priority Queue Dynamic wavelength and bandwidth allocation algorithm is presented, which fairly allocates the network resources, in order to meet the QoS demands of Tactile and other types of medical applications. Extensive simulation results are presented, that indicate the effectiveness of the proposed algorithm, which is shown to outperform other well-known schemes.
