: This paper introduces an adaptive routing approach based on buffer status and distance in a mesh overlay network: Thermal Field is used for considering buffer stage and distance is applied to select routing policy. The path selection process considers the Thermal Field as a metaphor for the buffer usage based on probability in order to avoid message loss by overloaded peers or delay because of big queues, otherwise routing by the shortest way. In addition, the probability of Thermal Field consideration relies on leftover distance to the target instead of using a global constant. The experiment results substantiated our approach using the adaptive probability of routing mechanism works effectively.
