Named Data Networking for Smart Grid Information Sharing

Abstract

The next generation of power systems, called commonly “Smart Grids”, is expected to be integrating various and several distributed power sources. Therefore, the system is becoming opened with several operators, users and actors instead of one main power system operator. To deal with this new aspect and keep the system operating safe, it is crucial to ensure an efficient communication infrastructure for information sharing across the whole system. In this paper, we propose a Content Centric Networking (CCN) based architecture called Named Data Networking (NDN) to enable the smart grid networking. This new concept presents many advantages, especially an efficient in-network caching and a content-centric paradigm instead of host-centric. A case of study has been developed to show the efficiency of the proposed information sharing networking for smart grid. Simulation results are presented to illustrate the impact of the content centric paradigm on the information sharing of the smart grid components. These results show that the use of NDN minimizes the bandwidth consumption over the network forwarders and speed up the data retrieval by dint of the in-network caching.
