Abstract

Cognitive networks are becoming extremely popular in the network domain. This paper proposes a novel concept in cognitive network management and protocol configuration, where any protocol of the TCP/IP protocol reference model can be extended to dynamically tune its configuration parameters based on "immediate past" performance. The approach is focused on inter-node cognitive adaptation which is fostered by the proposed Cognitive Information Service (CIS). Performance evaluation results are obtained for cognitive adaptation of main TCP flow control parameters and show good agreement with design objectives.
