Title: Wireless
Sensor Networks for Healthcare Monitoring Systems
Abstract
Healthcare systems
become a hot area for all of medical, computer, and networking field’s
researchers. They are trying to advance the existing healthcare services with
the improvement of sensor networks, medical devices, wireless communication,
middleware software, and end software applications. Health status monitoring
indoor and outdoor attracts many researchers in order to have early detection
of diseases, provide emergency help, and reducing the medical costs.
Due to properties of
wireless sensor networks, they are used widely in health monitoring systems.
Periodic physiological status of people must be collected using sensors and delivered
actors such as people under monitoring, doctors and coaches for several
purposes actors such as people under monitoring, doctors, and coaches for
several purposes through communication system. Beside this periodic data, these
systems must provide emergency status reporting under critical situations.
Different vital signs can be gathered depends on the purpose of healthcare
system and what it is concern. The commonly used vital signs are heart rate,
pulse oximetry, body temperature, electrocardiography and blood pressure.
In this seminar, I will present existing healthcare systems that
are based on wireless sensor networks and I will provide a discussion of
advantages, issues, and design consideration of implementing healthcare system.

Title: Wireless
Energy Harvesting Sensor Networks for the Smart Grid
Abstract
Wireless Sensor Networks (WSNs) are
promising option for monitoring the smart grid with low cost to cover large
geographic areas. In wireless sensor networks, nodes are very tiny in size and
store small amount of energy with limited powered battery that may make a
bottleneck in the performance for continuous monitoring. It is very important
to increase the lifetime for the battery as well as removing the option for
changing every time it runs out due to the difficulty of reaching the sensors.
From the recent past, it has been
observed that there were several incidents in the electrical power grid where
the major reason for the collapse was spread from one faulty line to another
one. So, this could be avoided if the initial faulty line was identified and
necessary measure was taken in time. Hence, the necessity of situational monitoring
tool is important to escape from large-scale interruption of electrical
services.
This model will be used for
replenishing the battery charge of the sensor nodes of wireless sensor network
based on Radio Frequency (RF) wireless energy transfer that uses
electromagnetic waves and operates in the data communication protocol medium.
There are some other researchers who emphasized on using the ambient energy
source for replenishing the battery power. But it is not controlled and
straightforward due to unavoidable environmental changes. Thus, RF-based
wireless energy transfer comes into the focus.
