Outline

• What’s new?

• What’s next?

What’s New?• Introduction text has been cleaned• Taxonomy of components has been refined in

section 3– Elaborating on smart metering and distribution

monitoring contexts• Use cases (section 4) have been elaborated

– Yielding refined requirements on self-organization capabilities, periodic and unsolicited measurement contexts, and alert notification

• U-LLN application requirements section now introduces the need for anycast capabilities

• Security Considerations section has been elaborated

Smart Grid and Advanced Metering Infrastructure (AMI)

• Urban networks composed of smart meters and distribution monitoring sensors

• Forward and reverse traffic flows– interval data, alerts– demand response, service disconnect

• Internetworking (e.g. home network)

• Self-configuration and self-organization across large numbers of deployed nodes

On Autonomy

• Dynamically adapt to ever-changing conditions of communication (e.g. yielding QoS degradation)

• Dynamically compute, select and possibly optimize the (multiple) paths that convey traffic towards actuators and access points– According to service-specific, traffic-specific,

traffic engineering and security policies (among others)

Pending Issues and Next Steps

• Considerations on node mobility need to be provided

• Plan is to submit v02 after Dublin and suggest WG LC

• Comments are very much welcome!
