The Routing Protocol for Low-Power and Lossy Networks (RPL) is a standard routing protocol designed for resource-constrained environments like the Internet of Things (IoT). RPL is a distance-vector routing protocol that establishes a Destination-Oriented Directed Acyclic Graph (DODAG) to route packets between nodes. However, RPL does not explicitly consider node mobility, which can lead to performance degradation in mobile IoT networks. To address this issue, AI-powered mobility-aware RPL protocols in cooja projects have been proposed. These protocols use AI algorithms to predict node mobility and proactively adapt the DODAG to maintain connectivity and minimize packet loss.

Cooja Simulation

Cooja is a network simulator specifically designed for simulating the Contiki operating system, which is widely used in IoT devices. Cooja provides a realistic simulation environment to evaluate the performance of RPL under various network conditions, including node mobility. AI Algorithms for Mobility Prediction

Various AI algorithms can be used for mobility prediction in RPL. Common algorithms include:

" Machine learning: Machine learning algorithms can learn patterns in historical mobility data to predict future node movements. For example, a support vector machine (SVM) can be trained to classify nodes as stationary or mobile based on their movement patterns.

" Reinforcement learning: Reinforcement learning algorithms can learn optimal mobility prediction strategies by interacting with the simulated network. For example, a Q-learning algorithm can learn to predict node movements based on rewards and penalties received for its predictions.
