Advantage of u-Health
Expansion of supplier and consumer
Expansion of time and space
Care of health at all times without special diagnosis time
Recognition of health out of the hospital
Several communication or healthcare companies can offer the medical service
Healthy people can also use the medical service

Advantage of u-Health – Contd.
Reduction of cost
Various services
Treatment, examination-> precaution, consultation, custom treatment
Reduction of medical cost by precaution of disease and minimization of movement
Daily healthcare
Change of concept about medical service Improvement of health

Current Research of Sensor Network– How can we raise the reliability of data?
– How can we avoid the collision of data?
– How can we put a device to sleep when there is no packet to
transmit?
– When we wake up a device? And how?
– How can we improve the delivery latency of end-to-end?
– How can we transmit when source node is far from sync
generator?
Research Topics of Sensor Network
11
BAN (Body Area Network)
Conventional Concept
Establishment of networks by
attaching sensors around a
person
One central node andseveral local nodes
Ref. : IMEC

USN vs. BAN
• What is the difference between USN and BAN?
USN
Many Nodes
Wide Environment
Low relation between data
packets
BAN
Several Nodes
High relation between data
packets
Person
Routing considering wide environment Routing considering biological signals
