FlexRout: Dynamic Routing in Blockchain Networks

Blockchain is highly dependent on network topology and routing paths for efficient operation. The speed and effectiveness of mining are impacted by network topology, as a well-defined routing path improves the speed of mining by the faster exchange of data for verification. However, high traffic on the path, caused by the exchange of messages among the miners leads to delays in the routing path and lengthens the time needed for mining data. Moreover, the dynamic addition and termination of miners from the network affect the topology, further contributing to delays in the mining process and transactions. To address these challenges, we present a novel system called <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">FlexRout</i> that dynamically predicts the optimal routing path to increase the speed of the mining process. It firstly predicts miners (nodes) who can leave mining by checking their resource availability. Simultaneously, it also grants a reward or a penalty depending upon the right or wrong prediction made respectively. Experimental results demonstrate that <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">FlexRout</i> can significantly reduce traffic by almost 49% and latency by 50%.
