PPT: A Push Pull Traffic Algorithm to Improve QoS Provisioning in IoT-NDN Environment

Abstract

Internet of Things (IoT) is the convergence of connecting people, things, data, and processes. Named data networking (NDN) is a recent paradigm perceived for the future internet architecture to tackle the exponential increase in the volume of global IoT traffic. Traditionally, NDN supports PULL traffic, but IoT applications embrace both PULL and PUSH traffic. In this letter, we propose a hybrid PUSH-PULL traffic (PPT) model, for efficient data exchange in IoT applications. Simulation results indicate that our PPT algorithm can reduce the network load by 50% compared with the traditional IPv6, which in turn helps in almost 98% packet delivery ratio and no packet drop. The average throughput of our PPT model is 50% better than the IPv6 approach, which ensures a reliable IoT model.
