Forwarding Strategies in NDN-based IoT Networks: A Comprehensive Study

Abstract

Named Data Networking (NDN) is a new communication model that proposes to shift the manner to do networking by fetching data by names instead of host addresses. This data-driven architecture is considered promising for the Internet of Things (IoT) applications due to its inherent characteristics, such as naming, caching, and stateful forwarding, which give NDN the power to support natively, without adaptation mechanisms, the major requirements of the IoT environments. Nevertheless, particular management should be provided by the forwarding protocols when handling the limited resources of the IoT objects. This paper is devoted to investigating NDN-based forwarding strategies for the IoT, along with a comprehensive comparative study, followed by a simulation of some representative schemes. Insights on the main observations learned from the conducted evaluation are presented in the paper, highlighting the strengths, weaknesses, and suitability of every benchmarked solution in the context of NDN-IoT twinning.
