This presentation attempts to give an overlook of - What is BSN ? - Applications of WBSN -Challenges and Solution -Monitoring Pre-Schoolers using WBSN

1. Wireless Body Sensor
Networks
And its Applications
Presented By:

2. • Body Sensor Network (BSN) is used to
describe the application of motes that will
enable wireless communication between
several miniaturized Body Sensor Units (BSU)
and a single Body Central Unit (BCU) worn at
the human body

3. • BSN can be broken into three tiers:
Intra-BSN Inter-BSN Beyond-BSN

4. Type of sensor Function
Ear-worn activity
recognition (e-ar)
sensor
Used for capturing the
posture, gait and activity
of the patient
Wound healing
sensor
Used for monitoring the
Progress of healing for
burn patients
Blood pressure
sensor
Used for measuring the
Blood pressure for
patients with hypertension
Electromyograph
y (emg) sensor
Used for capturing the
muscle activities of
orthopaedic patient
Blood glucose
sensor
Used for measuring the
Glucose level of diabetic
patients
Heart rate sensor Used for detecting
abnormal
Heart conditions of cardiac
patients

5. • Human vision
restoration by retina
prosthesis.
• Proteus digital health’s
"ingestible sensor" (1
sq.mm chip).
• Biosensor Tattoo stops
athletes from crashing,
by reading lactate level
Implantable
Wireless Body
Area Network

6.  Pre-schoolers are very active
 Hard to keep track of them
 Bio sensors could help
 Tracking using Sensors
attached in name tags, wrist
band or belts.
 When they approach danger
teachers are informed via
access points and then to
their PDAs.
 Children’s health condition is
also monitored

7. • Unobtrusiveness
• Sensitivity of Sensors
• Effective Methods for Data Collection
• Compatibility Problems
• Transport Layer Challenges
• User-Friendliness
• Mobility
• Data Security and
• Privacy

8.  Data Security: Data is securely stored and transferred
 Data Privacy: Data can be used only by authorized people
 Application scenario:
◦ Emergency; paramedic reads RFID* tag to get the patient’s medical
records and his profile.
◦ WBAN is set up with wearable sensors
◦ Nurse reads health data from WBAN and uploads data onto local
network
◦ Patient’s gateway device is configured with an Access Policy (AP) that
grants access to records (also adapts automatically)
◦ Patient can adjust his AP to hide sensitive data

9. 1. Proposed by Wang et al.
2. Dynamic Integrity Check:
Each storage node computes
and broadcasts an algebraic
signature on one data shares
 Pros: Data confidentiality,
dependability and dynamic
integrity achieved simultaneously
 Cons: No third party (say, the
local server) can perform integrity
checks.

10. • BSN sensor will be integrated in the form
of a silicon chip of sub-millimetre size.
• By integrating analogue processing and
digital control onto the silicon chip,
significant power reduction and increase
in computation power can be achieved.
• BSN sensors will get more and more
pervasive, and sooner or later they will
gradually be weaved like a fabric in our
lives
