Performance comparison of Wi-Fi and LTE for Internet of Things on named data networking

The Internet of Things (IoT) is connecting tons of devices connected to internet, with high dynamicity and heterogeneity devices. IoT presents significant challenges from the wireless communications perspective besides the limitation in IP resource. It calls for new connection architecture based on data-centric approaches, namely Named Data Networking (NDN). Besides the Wi-Fi connection that widely used in IoT, NDN is challenged by the opportunity to re-architect the latest mobile network, that is Long-Term Evolution (LTE), through named-based communication. LTE could be a solution of limitation on Wi-Fi coverage area. In this paper, the experiment is conducted to compare the performance of NDN architecture over Wi-Fi and LTE, in order to show the possibility of LTE running over NDN. NdnSIM tool has been used to simulate the scenarios on IoT devices. Due to its simulation performed in a small-scale network for the simulation scenario, the result shows that the collection time between Wi-Fi and LTE over NDN, with varied number of producers, is the same. However, LTE has an advantage in further coverage distance that Wi-Fi connection cannot achieved or performed.
