Abstract: demands are also increasing. Hence patient health monitoring

Abstract:
The recent advancements in
technology and the availability of the Internet make it possible to
connect various devices that can communicate with each other and
share data. The Internet of Things (IoT) is a new concept that allows
users to connect various sensors and smart devices to collect
real-time data from the external environment.

IoT is able
to provide advanced level of services to society, business. Things
get interesting when smart devices combined with smart services to
create compound application.
IoT devices are
used in many fields. They make the users’ day to day life more
comfortable.
IoT
can be used in different areas such as manufacturing or business,
retailing and security.

As
population is increasing day by day, caretaking demands are also
increasing. Hence patient health monitoring systems are gaining
importance these days. It’s important to
monitor various medical parameters. Hence the IOT can play a major
role in Healthcare applications. Different
sensors are used to collect temperature, blood pressure, sugar level
etc., which are used to evaluate the health condition of the patient.
Communicating the collected information to the doctor, making
accurate decision on the data collected and notifying the patient is
the challenging task in the IoT.

INTRODUCTION

Health
is one of the most important challenges for human being. In hospitals
there are doctors and caretakers for continuous monitoring the
patients. Their ECGs, heartbeat, temperature are continuously
monitored. There is no provision to check the parameters when the
patients return to home. Patient’s data (temperature, heart rate,
ECG, position) can be frequently measured and sent to server. Period
of transmission can be set. Using webpage, doctor can view his
patient’s health status. When any of the parameter goes beyond the
threshold value he will get an alert notification.

Internet
is very important part in our day to day life. Internet has changed
how people live, work, play and learn. It serves for much purpose
finance, educations, Business, Entertainment, Industries, Shopping,
Social Networking, etc. Internet of Things (IOT) is the next new mega
system of Internet. This visualizes a world where several objects can
sense, communicate, share information over an Internet Protocol (IP).
The objects which are connected collect the data, analyze and used to
initiate required action which provides an intelligent network for
analyzing, planning and decision making. It is generally considered
as connecting objects to the Internet and using that connection for
control and remote monitoring of those objects. This definition was
only a part of IOT evolution considering the machine to machine
market today. Actual definition of IOT is creating a brilliant
invisible network which can be controlled and programmed through
internet. Products developed based on IOT including embedded
technology which allows them to exchange information among each other
or the Internet and it is assumed that around 8 to 50 billion devices
would be connected by the end of 2020. Since these devices come
online, they provide better life style, create safer, more engaged
communities and revolutionized healthcare. This entire concept of IOT
stands on wireless network, sensors and gateway, which enables user
to communicate and access the application/information consequently
add to an IOT framework which gives secure health awareness checking.
