INTRODUCTION• Patients need continuous monitoring of their
health conditions
• Various vital and health care data are collected using sensors and sent to the hospital

Proposed Needs• Low complexity
• Low cost
• Data reliability
• Low power consumption

MEDIC• Acquire data from patients in real world• It sends data to the centralized server
and the centralized server forwards data to all the nodes
• It can be configured from the remote server
• Wearable sensors to patients for comfort ability

What is ZigBee??ZigBee technology is a low data rate, low power
consumption, low cost, wireless networking protocol targeted towards health care
Zigbee Alliance introduced Zigbee standard protocol in 2003
ZigBee is a technological standard, based on the IEEE 802.15.4 standard, which was created specifically for control and sensor networks.

The Zigbee Protocol Stack

What is ZigBee??• As can be seen in the figure, IEEE 802.15.4
develops the Medium Access Control (MAC) Layer and Physical (PHY) Layer, which address such things as the frequency and data rate specifications.
• ZigBee develops the Network Layer and Application Layer, which includes the Applications Support Sub layer, the ZigBee Device Object, and the Security Services.

BAYESIAN NETWORK ALGORITHM
• A set of variables independent of each other• The probability of these variables influence
the output• Symptoms are used to determine whether a
person has a disease• This is trained by the previous data used for
the treatment

Timezone CoordinatedSleep Scheduling Algorithm (TICOSS)
• coordinated sleeping through the division of the network into time zones• The time zones also provides coordinated
sleeping, through the V-table scheduling• The scheduling table allocates timeslots to
nodes in order to assign periods of node activity and inactivity

TOPOLOGY MODELS
• It manages all the sensors inside the network• It collects information from all the nodes and
forwards it to the centralized server

TOPOLOGY MODELS Fully functional device Any topology fits for fully functional device It can also act as a network coordinator, network
router
Reduced functional device It only fits perfectly for reduced functional device It cannot act as a network administrator

Future???ZigBee is seen as a key technology for home
automation and sensor networks, but its characteristics can be extremely valuable in some healthcare applications as well.
On July 24-27, 2006 in the Free scale Technology Forum, Orlando, FL, the wireless developer Cambridge Consultants demonstrated how ZigBee's unique networking attributes can be exploited to implement networks for healthcare.
