Power Management Technique for Energy-Efficient Communication Systems in Telemedicine

An embedded system is a specialized computer that is resource constrained to sense and control its environment. Embedded systems usually consist of hardware and software. The mostly used hardware materials are processors, peripheral communication devices, actuators, sensors, power supplies, and memory storage. The application-specific algorithms, device drivers, and operating systems are the typically used in software section. Normally need a standard protocol to communicate the particular type of embedded system, for example, nodes in sensor networks are the specialized embedded systems. Sensor nodes with wireless communication capabilities can form wireless sensor networks (WSN). Normally two types of wireless networks are used, such as personal area networks (PAN) and wireless sensor networks (WSN). The WSN can contain hundreds or even thousands of sensor nodes. The WSN used in industrial applications and can be deployed in hazardous environments, such as in battlefields, volcanoes, and wildfires. Personal area networks usually require measurement, and minimization devices are implemented in small numbers. PAN devices are designed for Wi-Fi and Bluetooth common-use technologies and standard protocols, for use such as web browsing, file transfer application, audio and video streaming application. Today’s research in WSN focuses on generating large-scale network system of electricity using very specialized algorithms. They usually feature exhibits for science, hospital, military, and professional use usage scenarios. Therefore, this research work introduces hybrid method to reduce the power consumption of WSN used in hospital based on patient healthcare monitoring system. To reduce the power consumption in wireless sensor networks (WSNs) for healthcare systems has generated tremendous efforts in recent years. In any case, in a large portion of these investigations, sensor information handling assignments, for example, health decision-making and emergency reaction, the message is sent by the remote server. The proposed system consists of sensor nodes, central processing control module, and transmitter with indicator and receiver module. This research work uses direct power management technique to control the base station – to disable the working of unused nodes, and self-executing path resource allocation (SERA) method is used to detect the active nodes through WSN in receiver side. The direct power management (DPM) technique is used to reduce the power consumption in sensor nodes for base station. The DPM is the effect of initializing the energy of each sensor node without significantly degrading performance when reducing system power consumption. The basic idea is to turn off or not need to sleep mode devices and wake them up when needed. If the energy and performance overhead of the sleep-state transition is negligible, the genetic algorithm is executed so that the idle speed will be perfect when the system enters deep sleep state. A large sensor networks that are environments also require the deployment of a large number of sensors such as for intelligent patient monitoring, object tracking, and low power consumption or high battery life using energy-efficient cluster formation algorithms. The proposed wireless sensor network system using self-executing path resource allocation (SERA) strategy is used to implement in the hardware implementation using ARM Cortex-A 72 controller. This implements an analysis of the energy consumption of the system. The experimental and simulation results of proposed system shows low-power energy-efficient data transmission with security, reduce the packet losses, and improve the throughput ratio.

Influence of Reduced Noise Levels on Human Health During Quarantine Lockdown

The coronavirus disease (COVID-19) pandemic is one of the greatest challenges humanity must overcome and a defining global health crisis of our time. With the initial outbreak in December 2019, the acute respiratory disease has had an exponential rate of infection and a staggering death toll. There is experimental evidence suggesting an interaction between environment and virus mechanism using the aggregation-disaggregation process. As a result of this, risks factors for humans being infected increases. For example, in the current scenario, the COVID 19 virus and air pollutants both result in acute respiratory infection among humans. Hence, it becomes impendent to understand the interactional patterns of relationship between the environment and human beings. With the advent of urbanization and technological advancement, there has been a high amount of depletion rate of the environment in terms of pollution, climate change, inadequate natural resources. This chapter brings in a distinct focus on environmental noise and its impact on humans. Noise is an unwanted sound characterized by intensity, frequency, periodicity and duration. Environmental noise pollution has become widespread in the form of industrial noise, traffic noise, to name a few. Chronic noise can be placed at parallels with chronic psychological stress and can affect general health and well-being. Further, noise pollution has also been seen to lead to medical, psychological and social issues. To minimize the spread of community transmission of the disease, several countries including India underwent periods of lockdowns and everyone was confined to their homes. The pandemic with its chaos and unpredictability also brought a drastic change in the environment as man-made activities were at its lowest during the quarantine/lockdown periods. This chapter aims to highlight these changes concerning decreased environmental noise. Further, using the lockdown activities as baseline, we propose a positive psychology perspective and principles of mindfulness that can bring about the pro-environmental behaviour during this crucial period.

Green Technologies for Handling and Management of Biomedical Waste

Biomedical waste management is of great significance because biomedical waste can adversely affect health, causing serious implications for people who come into contact with it. Segregation, storage, and safe disposal of biomedical waste is the key to effective management of it in a workplace. The health of a community or a society is estimated according to the health status of each individual residing in it. Various factors affect community health. One of the major factors associated with it is waste generated by health care institutions. Waste generated by health care activities includes a broad range of materials, from used needles and syringes to soiled dressings, body parts, diagnostic samples, blood, chemicals, pharmaceuticals, and radioactive materials. The biomedical waste that is generated may carry risks of various infections and diseases (typhoid, cholera, human immunodeficiency virus, hepatitis, etc.) in the long run. Therefore, use of proper storage, disposal, and treatment techniques are needed in order to minimize waste generation by hospitals. Effective management procedures should be employed for proper prevention and control of these types of waste. Various methods are used for treatment of biomedical waste, such as chemical methods, mechanical processes, biological processes, and irradiation processes. Green technologies—such as water treatment, solid waste treatment, and air purification—also play major roles in management of biomedical waste. Governments need to make arrangements for dedicated trash bins to be provided for disposal of hazardous waste. Appropriate management strategies are crucial for preservation of an equilibrium between the environment and mankind.

Patients’ Health Surveillance Model Using IoT and 6G Technology

To upgrade the healthcare infrastructure, it is now possible to collaborate Information and Communication Technology (ICT) and the medical field together. After the pandemic of Covid-19 worldwide, it has been more crucial to renovate a new dimension to make the healthcare system more predictable, controllable, and handy. This chapter focuses on a patients’ health monitoring system model based on the advantages on IoT and 6G technology. It identifies a cluster of patients for whom a continuous surveillance over health is priority. About 30–35% of deaths occur each year because of the time delay in getting the right treatment or having obstacles and less facilities in the rural area. Lack of an even distribution of a sound treatment everywhere in the country is a big challenge. To overcome the geographical barriers and human intervention, we propose a wireless health monitoring model where treatment is possible from any location without thinking about physical distance or networking barriers. On one hand, Internet of Things (IoT) is making life easier in every sector including healthcare and disease management system. On the other hand, 6G technology is a newly known terminology in the field of wireless cellular communication. It can provide a sustainable healthcare system for the citizens and make wireless devices more viable to the community, even in the remote area. This chapter aims to combine the idea of these two utmost new technologies to provide a better health monitoring system for a sustainable future and also discusses healthcare system establishing challenges and possible solutions for a better health service and support. The major contribution we provide here is the deployment of two biggest technologies in the health sector to provide higher degree of automation, reduced operating costs, and fastest decision-making process.

Applications of Machine Learning and Internet of Things in Agriculture

With the rapid advancement of technology, people are passionate to get more intelligent living. Since agriculture is one of the significant industries that need to be developed in order to feed rapidly growing population. Thus, there is a need to support agriculture with technology in order to get the best yield. In recent years, automated field irrigation systems have been introduced to replace the traditional agricultural system. Lots of research have been carried out in smart agriculture. The intelligent agriculture is becoming one of the biggest applications of the Internet of things (IoT). IoT and machine learning have helped researchers to develop smart and reliable systems. There are many different systems such as crops irrigation system and crop health predication systems. These systems assist farmers to increase the productivity. The irrigation system can be categorized either manually or automatically. Manual irrigation needs a lot of time and effort. In comparison with automated irrigation, the automated irrigation system can conserve water and increase productivity because water is supplied only when it is needed with limited or no human assistance. Moreover, the plant may suffer from diseases, which negatively affects the yield. Therefore, it is necessary to identify the disease in the early stages and find an appropriate cure. Machine learning allows systems to learn and improve automatically from experiences. Hence, intelligence can be applied in interpreting agricultural data obtained and accordingly analyze data for predicting the output.

Internet of Things for Environment Protection and Sustainable Living

With the growing years, rapid changes are seen in both technology and the environment. But the issue is that these both diverse factors were never in hand with each other, that is, whenever growth is seen in technology, harm happened to the environment and considering the present pandemic situation where nature is reclaiming, all sectors are halted. So, the question arises as to how technology and the environment go hand in hand with each other. An intelligent answer to this would be the Internet of Things (IoT). IoT is a combination of different things such as devices, smart wearable objects, and interiors, which are embedded with sensors, actuators, software, and other technologies where interaction happens between them. Due to the connectivity between them, data are transferred. This book chapter presents algorithms that would help in the prevention of environmental issues and how the Internet of Things would help in the reduction of the harm that happened to the environments as well as how we protect the environment using technology. One of the important features of IoT is its ability to monitor real-time systems which would help us in keeping track of the environment’s actions. Vast disasters can be avoided, immediate rescues can be performed, and proper maintenance can be taken using the IoT. The main focus of this book chapter is on three factors – prevention, reduction, and protection. Each factor would display different algorithms and systems which would help in protecting the environment. Environmental impact assessment (EIA) and fault tree analysis can be used in evaluating and preventing any damages beforehand. After preventing the damage, reducing the harm is crucial. The waste reduction algorithm (WAR) helps in evaluating environmental impacts. Later on, the protection is done using IoT models.
