Energy Efficient Context based Forwarding Strategy in Named Data Networking of Things
Lenord Melvix J.S.M., Vikas Lokesh, George C. Polyzos · 2016
Named Data Networking (NDN) of Things has gathered interest among the Internet-of-Things (IoT) research community due to its hassle-free deployment and configurability. This approach to interconnecting devices provides the network with additional information about the data transported, which can be used for improved efficiency. This is one of the targets for mass IoT or Machine-to-Machine (M2M) communications modes of 5G. In this paper, we propose a context based forwarding strategy that makes forwarding decisions based on the tolerance to inaccuracies in data defined for the application requesting it. We also propose a modification to the hierarchical naming scheme by appending the name of the application generating the interest. In addition to faster context based forwarding, this modification simplifies the naming as it is easier to understand the context under which the interest was generated, even with generic names. We demonstrate an improvement in energy efficiency of the system using the proposed technique compared to an IP based implementation. In addition, the proposed technique offers a platform to implement application level access control and Quality-of-Service (QoS) support.
