<span style="font-size:12.0pt;color:black">Cognitive networking enables the creation of a self-adaptive network that can help to significantly reduce the manual configuration efforts needed to run the system. By implementing a continuous observation of the
network state, a cognitive network can independently recognize and adapt to changes in the environment or user demand. These properties can be particularly attractive for the reliable transmission of data bundles in challenged networks that can be affected
by erratic factors. In this talk, I will present our ongoing research efforts on cognitive networking methods for improving space communications. First, I will introduce a performance evaluation study of the Licklider Transport Protocol–a common convergence
layer choice. Through the use of analytical and computational methods not previously used for the study of LTP, we identify theoretical performance limitations and optimization opportunities with this protocol. Second, I will introduce a neuromorphic computing
approach leading to the design of a cognitive network controller. The controller uses a recurrent spiking neural network structure to learn and to decide the next optimal action. To demonstrate the main results of this study, I will then present the benefits
of introducing a self-optimizing block segmentation process to LTP through a simulation study of a space link. Our approach to cognitive networking offers a unique avenue for achieving an optimal use of space communications links. </span><o:p></o:p></p>
