Summary
This study introduces novel power management strategies for wireless e-Health systems to mitigate electromagnetic interference (EMI). Optimized relay placement using a genetic algorithm significantly reduces network outages, enhancing healthcare communication reliability.
Area of Science:
- Wireless communication
- Healthcare technology
- Electromagnetic interference (EMI) mitigation
Background:
- Wireless applications in electronic health (e-Health) offer benefits like faster data delivery and reduced costs.
- Electromagnetic interference (EMI) is a significant challenge in sensitive healthcare environments.
- Existing power management methods for EMI reduction can be inaccurate and increase network complexity.
Purpose of the Study:
- To propose new power management approaches for wireless e-Health systems in healthcare settings.
- To address the trade-off between reducing transmission power for EMI avoidance and maintaining quality of service.
- To decrease the probability of network outage in wireless healthcare communications.
Main Methods:
- Developed two power management approaches based on per-user location and hospital sectoring.
- Proposed the use of relays to decrease the probability of outage.
- Employed a genetic algorithm to determine optimal relay placement, considering delay and blind spot coverage.
Main Results:
- Simulations demonstrated the effectiveness of the proposed methods in reducing network outage probability.
- The genetic algorithm successfully identified optimal relay positions for enhanced network performance.
- The new approaches aim to improve the reliability of wireless healthcare communications.
Conclusions:
- The proposed power management and relay placement strategies effectively mitigate EMI and reduce outages in wireless e-Health systems.
- Optimized relay deployment is crucial for maximizing benefits in wireless healthcare networks.
- This research contributes to more reliable and efficient e-Health service delivery.

00:59Hospitals-II
Hospitals provide inpatient and outpatient services. Inpatient services provide care to patients that stay in the hospital for an extended period, ranging from days to months. Examples of inpatient services include intensive care units, hospital wards, or surgeries. Outpatient services provide care to patients who come to a hospital for a diagnostic or treatment but do not stay overnight —for example, diagnostic tests, surgical procedures, or health education.

01:28Hospitals-I
Hospitals offer medical and surgical care to the sick and injured, along with accommodation while they recover. At the same time, they also provide outpatient, emergency, psychiatric, and rehabilitation services to meet various community needs. In addition to providing medical care, hospitals also act as hubs for medical research and training. Hospitals use clinical procedures and evidence-based practice standards to deliver patient care. To deliver safe and efficient care, a nurse must stay up...
01:20Integrated Healthcare System
An integrated healthcare system (IHS) is a set of organizations that provides for or arranges to provide coordinated and continuous service to a defined population. The IHS takes responsibility for that particular population's health status and outcome, both clinically and fiscally. An integrated healthcare system is a well-organized, well-coordinated, and collaborative network. The integrated delivery system is a network that connects different healthcare providers to deliver organized,...
01:21Tertiary Healthcare System
Specialized care provided over an extended period is called tertiary care. Usually, a primary or secondary care physician will refer a patient to tertiary care. A patient's maximum physical and mental function is restored in tertiary care, which is caused due to the impact of a chronic illness or condition. Tertiary care aims to achieve the highest level of functioning possible while managing chronic illness. For example, a patient who falls and fractures their hip will need secondary care to...
01:26Methods Of Healthcare Delivery System
At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is limited...
