Performance analysis of RPL protocol in different nodes positioning using Contiki Cooja

The routing protocol for low-power and lossy networks (RPL) protocol, tailored for the internet of things and wireless sensor networks, enhances communication efficiency in low-power and lossy networks. This study employs the Contiki Cooja simulator to analyze RPL performance across random, linear, and elliptical node positions. Parameters, including power consumption, duty cycles, inter-packet times, packet reception, and routing metrics, are evaluated. Linear positioning demonstrates superiority across critical parameters, including power consumption, inter-packet time, packet loss, and routing efficiency.
