Resilient routing within low-power and lossy networks is essential to ensure the continuous and reliable operation of IoT devices. Standard RPL may struggle to adapt quickly and effectively to rapid changes in network conditions, such as link quality fluctuations, link failures, and varying traffic patterns, leading to suboptimal routing decisions, which can affect the QoS. In addition, IoT applications may express different QoS requirements that should be integrated within the routing decision. In this paper, we introduce a new extension of RPL, called Adaptive QoS-RPL, which can effectively adapt to changes in network conditions and node QoS requirements when building the DODAG. The experiments conducted using COOJA reported results that demonstrate the effectiveness of our solution compared to similar protocols.
