Sejong University (CSE)Protocols & Standards

Health

IEEE 802.15.4

Defines the operation of LR-WPANs (PHY & MAC)

10-meter range and a transfer rate of 250 kbps

RT suitability by reservation of guaranteed time slots

Collision avoidance through CSMA/CA

Three possible frequency bands: 868/915/2450 MHz.

Zigbee and BLE

Applications: Medical device data collection, healthcare, fitness, beacons, security, and home entertainment industries.

6LoWPAN Standard

Sejong University (CSE)Protocols and Standards

6LoWPAN– “IPv6 over Low-Power Wireless Personal Area Networks”

A networking technology or adaptation layer that allows IPv6 packets to be carriedefficiently within small link layer frames, such as those defined by IEEE 802.15.4. T

RPL: Routing for Mesh topology network to achieve long range communications

RPL is located at the IPv6 and is not interfaced directly to the lower level protocols, sothat it's easy to integrate to any connectivity solutions

UDP Fragmentation

Constrained Application Protocol (CoAP)

CoAP has lower communication overhead compared to HTTP

CoAP headers are represented using binary coding to minimize payload overheads

HTTP transaction bytes are 10 times higher than CoAPtransaction bytes

User Datagram Protocol (UDP)

Packets are transmitted over UDP instead of TCP

UDP is suitable for lossy networks with limited bandwidth

Sizes of UDP headers are smaller than TCP headers

UDP does not require 3-way handshake

ISO/IEEE 11073 Health Informatics Standard

Enables communication between medical, health care and wellness devices and with external computer systems.

Personal health and fitness devices: Glucose monitors, pulse oximeters, weighing scales, medication dispensers and activity monitors.

Continuing and acute care devices: Pulse oximeters, ventilators and infusion pumps.

MIDI- Medical Data Information Base; CMDISE- Common Medical Device Information Service Element; ACSE- Association Service Control Element

RT plug-and-play interoperability.

Efficient exchange of care device data.

RT plug-and-play interoperability.

Efficient exchange of care device data.
