Abstract: Low-power and lossy networks (LLNs) are critical components of the IoT ecosystem. These networks are distinguished by common characteristics such as low resources and a high rate of packet loss. In 2012, the Routing Protocol for Low-Power and Lossy Networks (RPL) was suggested as a routing protocol for such networks. Even though RPL is now standardized and widely acknowledged, there are still areas for improvement, such as load balancing, stability, routing, and mobility support. This review work focuses the limitations and open challenge in RPL. Many researchers are attempted to address this issue in the literature by developing various routing measures that address various aims. This review work makes assessment of the RPL works, their strengths and shortcomings, and provides future directions on the issues.
Keywords: IoT, LLNs, RPL, Routing, Challenges.
