M2M Applications
• M2M applications include [2]
–
–
–
–
Smart metering
Health monitoring
Vehicular
Maintenance
• Some application cases & related requirements
– Simultaneous transmissions of different traffics
– Devices with limited power
– High reliability transmission
Simultaneous Transmission of
Different QoS Traffics
• M2M devices may be transmitting traffics of different
QoS requirements.
– Smart metering
• Power outage notification
• User electricity consumption profile
– Health monitoring
• Vital problem warning
• Your walking distance
• Prioritized transmission is required
– Pre-emption is required for critical traffic
– Consider delay & reliability
Devices with Limited Power
• Most mobile devices are powered by batteries.
– Hand-held devices
– Sensors, public monitoring devices
• Energy saving is necessary
– MAC protocol should be integrated with power
saving mechanism
• To maximize power saving
– Efficient energy saving protocol
• For delay tolerant traffic
High Reliability Transmission
• The integrity of critical control message or
data should be ensured.
– Public warning devices & signals
– Emergent reporting for the M2M consumers
• Feedback is necessary to ensure the
transmission and reception.
– HARQ with ACK/NACK
– Fountain codes, network coding
Proposed Text to the IEEE 802.16p M2M SRD (1)
• 6.2.4 The 802.16p system shall support optimized signaling
for resource allocation for large numbers of M2M devices
individually or by group.
– 6.2.4.1 Pre-emptive resource allocation should be provided if
emergent signaling or data delivery is required.
• 6.2.5 The 802.16p system shall support efficient and reliable
control and data delivery to and from groups of devices.
– 6.2.5.1 Control and data delivery to and from groups of devices
shall be categorized, based on delay requirements and reliability
requirement.
– 6.2.5.2 Delay-bounded group data delivery mechanism shall be
provided to disseminate delay-sensitive information to/from a
group of M2M devices.
– 6.2.5.3 Feedback mechanism may be provided to ensure the
reliability of critical control and data delivery to/from M2M
devices for mission-critical M2M transmission.
Proposed Text to the IEEE 802.16p M2M SRD (2)
• 6.2.6 The 802.16p system shall support efficient mechanisms
for network access from large numbers of M2M devices.
– 6.2.6.1 Energy-efficient group data delivery mechanism shall be
provided to disseminate delay-tolerant information to/from a
group of M2M devices. The energy-efficient group delivery
mechanism shall be integrated with power saving mechanism of
M2M devices.
• 6.2.8 The 802.16p system shall provide mechanisms for
allowing access with different levels of priority for M2M
devices across different classes of M2M services.
– 6.2.8.1 The access of different M2M services shall be pre-emptive.
M2M transmission with higher priority level should be able to gain
access from low level ones.
