Hop count, ETX and energy selection-based objective function for image data transmission over 6LoWPAN in Internet of Things

Abstract

Internet of Things (IoT) is a technology which connects millions of things to the internet for collecting data and controlling things. 6LoWPAN is designed with the idea to connect resource-constrained IoT devices. The current design of 6LoWPAN poses several challenges to support multimedia IoT devices such as cameras and audio recorders. This paper addresses one of the challenges in the area of parent selection with a new hop count, ETX and energy selection-based Objective Function (OF) for multimedia data traffic. The performance of the proposed OF is compared with existing OF with respect to packet delivery ratio, control traffic overhead, energy consumption and latency running simulations on different topologies in Cooja. The results of the simulations indicate the proposed OF performs better than existing methods in all the areas measured. Experimental results mention that the proposed HEE-OF improves PDR, overhead and energy parameters by 4%, 6% and 3%, respectively. © 2024 Inderscience Enterprises Ltd.
