3. INTRODUCTION
As information and Communication Technology emerges, people’s
interest in ubiquitous Health care System increases. The demand for
“anytime, anywhere” health care support attracted many researchers
to conduct a deep study for optimized Location Based Service (LBS).
The patient’s location can be tracked by Global Positioning System
(GPS) through mobile devices such as PDA, cellular phones and other
mobile devices. In this service, the patients can freely move or transfer
location in the place they want.
The IP enabled motes is attached to the patient’s body to get the
biomedical data such as ECG, pulse and temperature. IP-based
healthcare system used 6lowpan stack on TelosB mote in TinyOS
environment. TelosB motes are fully supported to the 6lowpan stack
and existing IP-based networks. The motes fixed on the patient body
for transmitting continuously healthcare data such as heart rate, three-
lead electrocardiography, body temperature, etc

4. BACKGROUND
The system used IEEE 802.15.4 standard 6lowpan with integrated
IPv6. For healthcare system we added LOAD (6lowpan Ad-hoc on
Demand Distance Vector) and MAC (Medium Access Control) protocols
in Harvan’s 6lowpan stack. 6lowpan stack has ability to connect the
physical environment in real-world applications such as healthcare,
wireless sensor network, network technology etc. IP-enable motes set
on the patient body for retrieving biomedical from body in PAN. PAN
network connected PC via gateway or base station for further analysis
or to the doctor’s PDA (Personal Digital Assistant). The doctor can
recognize or analysis patient data from anywhere on globe by internet
service provider equipments (PDA). Result shows the performance
biomedical data packets in multi-hope routing as well as represents
the topology of the networks. TelosB motes were tested on octopus
simulator in tinyOS2.02 for performance of biomedical data
communication and network topology [1].

5. LOCATION BASED SERVICE
LBS is an information or service, accessible with mobile devices
through the mobile network and utilizing the ability to make use of the
geographical position of the mobile device. LBS include services to
identify a location of a person or object, such as discovering the
nearest banking cash machine or the whereabouts of a friend or
employee. LBS include parcel tracking and vehicle tracking services.
LBS can include mobile commerce when taking the form of coupons or
advertising directed at customers based on their current location. They
include personalized weather services and even location-based games.
They are an example of telecommunication convergence. Now location
based service is being design for Healthcare system where the demand
for healthcare services available anytime and anywhere.

6. IP-BASED UBIQUITOUS HEALTHCARE SYSTEM
Design patients BAN (Body Area Network) have
set on TelosB sensor motes for continuously
communication biomedical data in a PAN. It would be
connected to the IPv6 based network via gateway or
base station. The multi-hop routing protocol
wirelessly transmits all health related data to the
gateway; it should be connected to the internet. It
would be connected to the IPv6 based network via
gateway or base station. The multi-hop routing
protocol wirelessly transmits all health related data to
the gateway; it should be connected to the internet. It
would be connected to the IPv6 based network via
gateway or base station [1]. The IEEE 802.15.4
standard defined reduced-function devices (RFDs) Physician
such as biological sensor motes and full-function Fig. 1 IP-based Ubiquitous Healthcare System
devices (FFDs) such as 6lowpan motes [8].

7. Internet Protocol version-6 over Low power Wireless Personal Area Networks
(6LoWPAN) stack based biomedical sensor motes can be fixed on the patient body for
retrieving health related data [8]. The IEEE 802.15.4 standard defined reduced-function
devices (RFDs) such as biological sensor motes and full-function devices (FFDs) such as
6lowpan motes [4]. The MAC layer beacons RFD motes commutate only FFD motes via
master/slave topology and the FFD motes communicate both RFD and FFD via multi-hop
to the gateway or base station connected to the PC. Doctor directly checks the current
situation of his patient with the help of existing wireless technology or services such as
GPRS on his PDA or Mobile cell.
FFD connected to zero or more RFDs. It act as routers and connect the entire 6lowpan
network in a multi-hop routing. Each IP enable motes have single coordinator, which must
be FFD type and it’s responsible for address allocation and single 6lowpan. A PAN network
has numbers of devices controlled by the gateway.
TinyOS is the platform specifically designed for the wireless sensor networks. Its
architecture is based on components and lightweight threads. TinyOS is different from
other traditional embedded operating systems. When IPv6 Internet accesses to the sensor
network, it needs to use a web interface and the serial forwarder that operates in the
applets enables reception/transmission of TinyOS packet over IPV6.

8. SERVICE MODEL OF HEALTHCARE SYSTEM
Then the positioning of the patient will be
started at the same time. Since the position data as
well as the biometric data have already been sent to
the hospital, we should transfer the patient as soon
as possible. In the hospital, a doctor can take care of
a patient easily with the previously received Satellite
information about the patient. Hospital
GPS helps Locate Ambulance, guides Ambulance
driver to destination Also, information on the time of
arrival of an ambulance reduces the preparation time Ambulance
loss, resulting in the fast medical treatment [3].
Also, while at inside the ambulance there is a
Video Conf system IPv6 based Video conf system,
which monitors the patient current condition thus, Patient
the physician monitoring the transfer of the patient
can give medical advice on how to treat a patient Fig. 2 Healthcare Service
while in the ambulance.

Above all things, custom healthcare service becomes
available for the patient. Custom emergency medical
treatment system is essential for the patient in the era of
Ubiquitous [3].

10. CONCLUSION
This new concept of IPv6 application for Ubiquitous
Healthcare plus Global Positioning System for Patient Location
Based Service is very ideal for fast treatment and real time
monitoring of patient. Ubiquitous healthcare and wireless
monitoring system through IP-enable biomedical sensors set
on the patient body area network idea was presented. The
Service Model of Healthcare System was discussed. For the
future, we want to work on the more efficient Positioning
system and more defined platform IPv6 ubiquitous healthcare
for more Efficient Location based Service.
