ETXRE: Energy and delay efficient routing metric for RPL protocol and wireless sensor networks

IET Wireless Sensor Systems, Volume 13, Issue 6, Page 235-246, December 2023., 2023
Expected transmission count remaining energy (ETXRE) is a new routing metric based on the combination of expected transmission count and the remaining energy routing metrics. ETXRE shows a great potential to save up on the consumed energy and lowering the delay, and gives exceptionally competitive results in the other areas (i.e. packet delivery ratio,
