Due to their high computation and communication, traditional protocols such as Optimized Link State Routing (OLSR) often struggle with frequent topology changes and limited resources. We propose Adaptive Hello OLSR (AH-OLSR) and Adaptive Hello Expected Transmission Count (AH-ETX), which dynamically adjust control message intervals based on neighboring nodes’ mobility. Our approach minimizes overhead and improves network throughput without modifying the message structure of OLSR. Simulation results demonstrate that AH-OLSR and AH-ETX significantly enhance efficiency (throughput normalized by control overhead), achieving up to a 143% increase compared with OLSR with static intervals. These advancements make AH-OLSR and AH-ETX suitable for real-world robotic swarm applications, supporting robust communication in challenging conditions.
