This review presents the integration of security analysis with Quality of Service (QoS) support in the Routing Protocol for Low power and Lossy networks (RPL). This study highlights the importance of the security and QoS. A methodology for security analysis and evaluation of QoS support was proposed. An algorithm for integrating security analysis and QoS support in RPL is presented, addressing the vulnerability assessment and dynamic adaptation of route selection. This review highlights the significance of research on enhancing security and QoS support in RPL and its potential to contribute to the field of low-power and lossy networks.
