A Named Data Network Approach to Energy Efficiency in IoT
Abstract
In the IoT, the trade-off between content availability and energy efficiency plays a crucial role. In this paper, we propose an energy-saving approach leveraging distributed caching for IoT content, based on an information-centric networking paradigm. We extend the NDN protocol with a variety of caching and replacement strategies, and we discuss alternative approaches for extending NDN to accommodate such IoT use cases. Based on experiments on real IoT hardware in a network gathering hundreds of nodes, we demonstrate these caching strategies can bring 90% reduction in energy consumption while maintaining IoT content availability above 90%.
