Information-Centric Approach for Smart Grid Communications
An information-centric approach for smart grid communications is being explored within the C-DAX Consortium, funded by the European Union. This approach focuses on leveraging information-centric networking (ICN) to enhance the delivery of various data services in the smart grid context, aiming to reduce complexity and improve efficiency. Through ICN, the network becomes aware of the content it delivers rather than just the end-hosts, enabling new interaction models like publish/subscribe and facilitating benefits such as multicast, mobility, and in-network caching. The publish/subscribe basics and the use of brokers further enhance the architecture, enabling decoupling of data production and consumption across a multitude of communicating devices.

Smart grid context Smart grid context Consume smart meter data Energy Data Services Multiple applications Consume EV charging data E-Mobility Service Provider Produce EV charging data Multiple actors Multitude of communicating devices Produce monitoring data Consume monitoring data Produce smart meter data Consume smart meter data Limited human intervention High configuration / management complexity
Information Information- -centric networking (ICN) centric networking (ICN) The network becomes aware of what it delivers, not where Primarily referring to named information objects (IOs), not end-hosts Routing and/or forwarding decisions based on IO names New interaction model: publish/subscribe Decoupling of communicating entities No end-to-end communication sessions Network mediates for the delivery of information Benefits Multicast, Mobility In-network caching and processing (if needed) Reduced application configuration complexity
Publish/subscribe basics Publish/subscribe basics Publisher Decoupling data production and consumption in space and time Communicating end-points need not know each other Asynchronous communication possible 1 2 3 Broker discovery service Broker Core components Publisher client: produces data Subscriber client: consumes data Broker: stores and forwards data Broker discovery service: indicates broker to publishers and subscribers - Can optimize its location - Can perform e.g., filtering/aggregation 4 4 4 2 1 Subscriber Subscriber Subscriber Basic interactions Broker discovery Client join Data dissemination Join message Data Broker Pub/sub middleware Application
