INTRODUCTION As information and Communication Technology emerges, people’sinterest in ubiquitous Health care System increases. The demand for“anytime, anywhere” health care support attracted many researchersto 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 othermobile devices. In this service, the patients can freely move or transferlocation in the place they want. The IP enabled motes is attached to the patient’s body to get thebiomedical data such as ECG, pulse and temperature. IP-basedhealthcare system used 6lowpan stack on TelosB mote in TinyOSenvironment. TelosB motes are fully supported to the 6lowpan stackand existing IP-based networks. The motes fixed on the patient bodyfor transmitting continuously healthcare data such as heart rate, three-lead electrocardiography, body temperature, etc
BACKGROUND The system used IEEE 802.15.4 standard 6lowpan with integratedIPv6. For healthcare system we added LOAD (6lowpan Ad-hoc onDemand Distance Vector) and MAC (Medium Access Control) protocolsin Harvan’s 6lowpan stack. 6lowpan stack has ability to connect thephysical environment in real-world applications such as healthcare,wireless sensor network, network technology etc. IP-enable motes seton the patient body for retrieving biomedical from body in PAN. PANnetwork connected PC via gateway or base station for further analysisor to the doctor’s PDA (Personal Digital Assistant). The doctor canrecognize or analysis patient data from anywhere on globe by internetservice provider equipments (PDA). Result shows the performancebiomedical data packets in multi-hope routing as well as representsthe topology of the networks. TelosB motes were tested on octopussimulator in tinyOS2.02 for performance of biomedical datacommunication and network topology .
LOCATION BASED SERVICE LBS is an information or service, accessible with mobile devicesthrough the mobile network and utilizing the ability to make use of thegeographical position of the mobile device. LBS include services toidentify a location of a person or object, such as discovering thenearest banking cash machine or the whereabouts of a friend oremployee. LBS include parcel tracking and vehicle tracking services.LBS can include mobile commerce when taking the form of coupons oradvertising directed at customers based on their current location. Theyinclude personalized weather services and even location-based games.They are an example of telecommunication convergence. Now locationbased service is being design for Healthcare system where the demandfor healthcare services available anytime and anywhere.
IP-BASED UBIQUITOUS HEALTHCARE SYSTEM Design patients BAN (Body Area Network) haveset on TelosB sensor motes for continuouslycommunication biomedical data in a PAN. It would beconnected to the IPv6 based network via gateway orbase station. The multi-hop routing protocolwirelessly transmits all health related data to thegateway; it should be connected to the internet. Itwould be connected to the IPv6 based network viagateway or base station. The multi-hop routingprotocol wirelessly transmits all health related data tothe gateway; it should be connected to the internet. Itwould be connected to the IPv6 based network viagateway or base station . The IEEE 802.15.4standard defined reduced-function devices (RFDs) Physiciansuch as biological sensor motes and full-function Fig. 1 IP-based Ubiquitous Healthcare Systemdevices (FFDs) such as 6lowpan motes .
Internet Protocol version-6 over Low power Wireless Personal Area Networks(6LoWPAN) stack based biomedical sensor motes can be fixed on the patient body forretrieving health related data . The IEEE 802.15.4 standard defined reduced-functiondevices (RFDs) such as biological sensor motes and full-function devices (FFDs) such as6lowpan motes . The MAC layer beacons RFD motes commutate only FFD motes viamaster/slave topology and the FFD motes communicate both RFD and FFD via multi-hopto the gateway or base station connected to the PC. Doctor directly checks the currentsituation of his patient with the help of existing wireless technology or services such asGPRS on his PDA or Mobile cell. FFD connected to zero or more RFDs. It act as routers and connect the entire 6lowpannetwork in a multi-hop routing. Each IP enable motes have single coordinator, which mustbe FFD type and it’s responsible for address allocation and single 6lowpan. A PAN networkhas numbers of devices controlled by the gateway. TinyOS is the platform specifically designed for the wireless sensor networks. Itsarchitecture is based on components and lightweight threads. TinyOS is different fromother traditional embedded operating systems. When IPv6 Internet accesses to the sensornetwork, it needs to use a web interface and the serial forwarder that operates in theapplets enables reception/transmission of TinyOS packet over IPV6.
SERVICE MODEL OF HEALTHCARE SYSTEM Then the positioning of the patient will bestarted at the same time. Since the position data aswell as the biometric data have already been sent tothe hospital, we should transfer the patient as soonas possible. In the hospital, a doctor can take care ofa patient easily with the previously received Satelliteinformation about the patient. Hospital GPS helps Locate Ambulance, guides Ambulancedriver to destination Also, information on the time ofarrival of an ambulance reduces the preparation time Ambulanceloss, resulting in the fast medical treatment . Also, while at inside the ambulance there is aVideo Conf system IPv6 based Video conf system,which monitors the patient current condition thus, Patientthe physician monitoring the transfer of the patientcan give medical advice on how to treat a patient Fig. 2 Healthcare Servicewhile in the ambulance.

Fig. 3 Inside the Ambulance Scenario Above all things, custom healthcare service becomesavailable for the patient. Custom emergency medicaltreatment system is essential for the patient in the era ofUbiquitous .
CONCLUSION This new concept of IPv6 application for UbiquitousHealthcare plus Global Positioning System for Patient LocationBased Service is very ideal for fast treatment and real timemonitoring of patient. Ubiquitous healthcare and wirelessmonitoring system through IP-enable biomedical sensors seton the patient body area network idea was presented. TheService Model of Healthcare System was discussed. For thefuture, we want to work on the more efficient Positioningsystem and more defined platform IPv6 ubiquitous healthcarefor more Efficient Location based Service.
