A Double per Priority Queue Dynamic Wavelength and Bandwidth Allocation Algorithm in Healthcare Applications Service

Abstract

The development of medical applications aims to upgrade the provision of services to patients and the healthcare staff involved. This upgrade can improve critical performance parameters of healthcare units such as reducing treatment time and saving both material and human resources. These state of the art applications, which include the Tactile Internet (TI) medical, have very high requirements from the communications network that supports them in order to ensure the required quality of services (QoS). The network infrastructure of healthcare units in turn needs to be upgraded in order to follow the evolution of the applications it must be able to support. Installing passive optical networks (PON) in healthcare environments is the best option for upgrading their telecommunication infrastructure. An important parameter for the performance of PONs is the effective allocation of their resources both in time and in frequency domain, with the entity responsible for the above operation to be the dynamic wavelength and bandwidth allocation (DWBA) algorithm. In this paper, we present a specially designed DWBA algorithm for healthcare environments that ensures the fair and efficient distribution of network resources, thus satisfying the required QoS to all categories of medical applications. The results of the simulation reveal that the implementation of the proposed algorithm in healthcare environments improves the metrics concerning the QoS provided, compared to others well known schemes from the literature.
