In ant-based routing protocols, the routing exponent controls how ants hop from node to node to discover routes based on pheromone values. It has been shown that stable multi-route solutions for small routing exponent values are dynamically connected to stable single-route solutions for large routing exponent values. These stable single-route solutions correspond to paths that have the smallest hop count. In this paper, we leverage this idea to improve the performance of ant-based routing protocols by dynamically adjusting the routing exponent. The results are validated via simulation.
