Routing Requirements for Urban Sensor Networks draft-ietf-roll-urban-routing-reqs-01.txt D. Barthel G. Chegaray M. Dohler (Ed.) C. Jacquenet G. Madhusudan T. Watteyne (Ed.) T. Winter (Ed.)

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!
