MAFC: Multi-Agent Fog Computing Model for Healthcare Critical Tasks Management

Abstract

In healthcare applications, numerous sensors and devices produce massive amounts of data which are the focus of critical tasks. Their management at the edge of the network can be done by Fog computing implementation. However, Fog Nodes suffer from lake of resources That could limit the time needed for final outcome/analytics. Fog Nodes could perform just a small number of tasks. A difficult decision concerns which tasks will perform locally by Fog Nodes. Each node should select such tasks carefully based on the current contextual information, for example, tasks’ priority, resource load, and resource availability. We suggest in this paper a Multi-Agent Fog Computing model for healthcare critical tasks management. The main role of the multi-agent system is mapping between three decision tables to optimize scheduling the critical tasks by assigning tasks with their priority, load in the network, and network resource availability. The first step is to decide whether a critical task can be processed locally; otherwise, the second step involves the sophisticated selection of the most suitable neighbor Fog Node to allocate it. If no Fog Node is capable of processing the task throughout the network, it is then sent to the Cloud facing the highest latency. We test the proposed scheme thoroughly, demonstrating its applicability and optimality at the edge of the network using iFogSim simulator and UTeM clinic data.

An IoT and Fog Computing-Based Monitoring System for Cardiovascular Patients with Automatic ECG Classification Using Deep Neural Networks

“…Each of the sensor nodes acquires ECG, respiratory rate and body temperature, and then transmits this data to an intelligent gateway, which communicates wirelessly with the system to analyze the information and make an automatic decision. Mutlag et al [ 36 ] developed a Multi-Agent Fog Computing (MAFC) model for healthcare critical tasks management, which significantly manages Fog computing resources by providing two levels of task prioritization (local and global). The MAFC model mapped between three decision tables to optimize the scheduling of critical tasks by assigning tasks with their priority, network load and network resource availability.…”

Artificial Intelligence and Internet of Things Enabled Disease Diagnosis Model for Smart Healthcare Systems

“…Numerous works have been conducted earlier to develop system that senses the physiological variables and health indicators to assess severe cases and accidents. Initially, Magaña Espinoza et al [5] applied Wireless Body Sensor Network (WBSN) to observe the heart rate and movement of users, whenever they require, even from remote areas. In this study, edge node is connected with internet and it forwards an alert (mobile phone) to family members, whenever important changes occur (early prediction of falls, tachycardia, or bradycardia).…”

“…Under the application of Artificial Intelligence (AI) models, surgical devices, and mixed reality applications, both diagnosis and disease treatment are highly robust [4,5]. By using AI, specific outcomes are attained from Clinical Decision Support System (CDSS) such as the diagnosis of hepatitis, lung tumor, and skin cancer.…”

A New Method With Swapping of Peers and Fogs to Protect User Privacy in IoT Applications

“…The number of devices that are connected to the internet is estimated in the billions [21]. With so many devices, cloud computing can no longer provide prompt response to the huge amount of smart applications, especially medical Apps, which are sensitively dependent on time [22], [23]. To meet such requirements, many solutions such as mobile clouds or multiple clouds and fog computing emerged [24] in 2012.…”
