Edinburgh Napier University Edinburgh Napier University Edinburgh Napier University Edinburgh Napier University The IPv6 Routing Protocol for Low-power and Lossy Networks (RPL) has been recently standardized as the de facto solution for routing in the context of the emerging Internet of Things (IoT) paradigm. RPL, along with other standards, has provided a baseline framework for IoT that has helped advance communications in the world of embedded resource-constrained networks. However, RPL still suffers from issues that may limit its efficiency such as the absence of an efficient load-balancing primitive. To address this problem, a novel load- balancing scheme is introduced that ensures a fair distribution of traffic among nodes while minimizing overhead
