Load balancing is a valuable approach to improve the energy efficiency of Wireless Sensor Networks (WSNs) that utilize the Routing Protocol for Low Power and Lossy Network (RPL). However, traditional RPL faces challenges in handling mobility, leading to disruptions in paths, increased energy consumption, and higher network delays. The integration of mobile nodes in Internet of Things (IoT) applications opens up opportunities for innovative services. This paper emphasizes the significance of load balancing and energy efficiency in RPL-based IoT networks and offers valuable insights into the ongoing research trends in this domain. Through load balancing and optimized energy consumption, RPL can enhance performance and prolong the operational life of IoT devices within networked environments.
