Abstract
This paper discusses changes to the Cognitive Space Gateway (CSG) approach to bundle routing to make it suitable for use with standard delay-tolerant networking (DTN) protocols and the High Rate DTN (HDTN) architecture. The revision removes the current convergence-layer information dependency of the CSG with an alternative mechanism that entails the exchange of performance-related data between adjacent nodes along the bundle path using extended canonical blocks. The proposed approach allows estimating learning rewards for the reinforcement learning method of the CSG using standard HDTN services. Possible changes to the HDTN architecture are also discussed to enable the implementation of dynamic routing decisions for bundles. The revised mechanisms are experimentally tested and the results both verify the suitability of the changes and offer a practical demonstration of cognitive routing capabilities with HDTN.
