This document discusses wireless body area networks (WBANs) and their applications. It first describes how WBANs can continuously monitor health and share information with remote care providers. There are two types of WBAN applications - medical and non-medical. Medical sensors include wearable sensors like pulse oximeters and electrocardiography sensors, as well as implantable sensors like glucose monitors and neural stimulators. The document also discusses WBAN challenges like power efficiency and security protocols. It concludes that WBANs have potential to improve healthcare by enabling early problem detection and improving quality of life.

2. • A system that can continuously monitor
the health condition of the people and
share information with remote care
providers or hospitals will be in great
demand.
• As an effort of catching up with this
trend, wireless body area network
(WBAN) has been emerged.

5. Pulse Oximetry:
It is a medical device that indirectly
measures the oxygen saturation levels in an
individual’s blood as well as the changes in
blood volume.
Electrocardiography:
The ECG waveform provides a non-
invasive means for investigating heart
function. ECG measurements using wireless
sensors are generally for ambulatory
applications.

6. Blood Pressure:
Measures the blood pressure of a person.

7. Glucose Monitoring:
Continuous monitoring was enabled by
placing an implantable sensor covered with a
multilayered membrane in the subcutaneous
tissue of the abdomen.
Implantable Neural Stimulators:
Implantable neural stimulators send electrical
impulses into the brain or spinal cord for the
treatment of Parkinson’s disease, intractable
epilepsy and chronic pain.

8. • WBANs must sense, process and
communicate data in a power efficient
manner.
• The majority of work in this area has been
on developing energy-efficient medium
access control (MAC) protocols.
• The protocol uses a strategy for data
routing between the sensor and the
gateway and a time division multiple
access (TDMA)-based MAC protocol.
8

9. Contention-based MAC protocols:
such as carrier sense multiple access/collision
avoidance(CSMA/CA).
Schedule-based MAC protocols:
such as TDMA, , access to the channel is
divided into time slots that are of fixed or
variable duration.
There are two main schemes used for
MAC protocols of sensor networks.

10. Bluetooth :
Bluetooth is a widely used
communication protocol for topologies
with master-slave architecture in
WBANs.
ZigBee:
Zigbee is used primarily in a star
topology of nodes, provides lower power
consumption, lower data rates and
longer battery life than Bluetooth.

14. •Signal & Path Performance
One might expect, the signal and path loss
inside the human body is drastically different
than the rules in plain space.
•Usability
Zheng's group classified this as usability
flaw, as the usefulness of emergency
detection sensors is in their detection of
emergencies that are not planned.

15. A WBAN is expected to be a very useful
technology with potential to offer a
wide range of benefits to patients and
early detection of possible problems.
Step by step, the evolutions will bring
us closer to a fully operational WBAN
that acts as an enabler for improving
the Quality of Life.
