IRTF icnrg interim meeting, 1/13/2015  Intuitively, data objects are a match for the requirements of applications using sensor networks, as opposed to communication endpoints and sessions  The characteristics of sensors and related network technologies may not match the requirements of IP very well  ICN architecture is feasible for sensor networks; where are the specific advantages in implementation, deployment, operation and application support?  If ICN is going to have an impact in the sensor network space, it has to do something better than current technologies. Why is ICN for Sensor Networks interesting?

Does ICN require fewer resources (CPU, memory, energy) for a stack/application implementation? Are there opportunities to take advantage of specific characteristics of the MAC/PHY transport to optimize the ICN application/stack? Opportunities in Wireless Mesh Networking

IRTF icnrg interim meeting, 1/13/2015  Routing IP in a mesh network requires mesh establishment, ongoing route management and other overhead. Can ICN name-based routing and object forwarding reduce overhead by using on-demand or geoloc routing?  There is overhead is associated with address assignment and management. Can ICN reduce overhead by using named objects rather than host addresses? Routing and Addressing

IRTF icnrg interim meeting, 1/13/2015  The IP model requires session security, access controls and other security features in a constrained device. Can ICN reduce or refactor operational overhead by using purely object security? Object Security… Application

IRTF icnrg interim meeting, 1/13/2015  Before ICN replaces IP, there will have to be a gateway function somewhere between ICN sensor networks and IP networks Can a “secure object” architecture bridge the gap?

IRTF icnrg interim meeting, 1/13/2015  …or, more generally, a push model for data object delivery  Not directly related to “what can ICN do better”, but some way is needed to address applications that currently don’t fit the Interest/Object message paradigm Is there an ICN solution for “push” model that is an improvement over the existing IP models? Designing for Actuators
