Edge-Assisted NDN-Based IoT Framework With Provider and Consumer Mobility Support

Abstract

The Internet of Things (IoT) mainly works based on point-to-point communications where the source performs an independent data delivery procedure to acquire data from the target. This leads to considerable data delivery costs and latency. The Named Data Networking (NDN) presents an efficient communication paradigm where multiple consumers can retrieve data from the optimal provider via one data delivery process, so we are motivated to exploit NDN to deliver IoT-based data and improve efficiency of data retrieval. However, it is challenging to deploy NDN in IoT due to essentially different architectures and features. Especially, mobility of IoT providers and consumers leads to frequent IoT-based data delivery failures. In this paper, we propose an Edge-assisted NDN-based IoT framework with Provider and Consumer mobility support (ENIPC) to overcome these challenges and reduce IoT-based data delivery costs, latency and failure rates. To overcome resource limitations of IoT devices, ENIPC integrates IoT with edge computing so that edge devices can help achieve NDN in IoT and multiple consumers can exploit reverse paths to retrieve multiple data via one data delivery process with provider and consumer mobility support. The experimental results demonstrate that ENIPC effectively decreases IoT-based data delivery costs and delays.
