Abstract

How to realize the cognitive capability is a key point to realize the cognitive wireless network. The research of cognitive wireless network is still at the primary stage, even not having a unique, accepted network architecture and implementation method. The construction of knowledge base in cognitive wireless network based on network situation-aware in the paper is deeply investigated in unfixed establishment network such as Ad hoc. The combination of NSGA-II and fuzzy decision is applied to constructing the knowledge base in cognitive wireless network from the aspect of network situation-aware and protocol configuration. Simulation result shows that: with variation of channel quality and network traffic load, performance will greatly be improved when the mechanism of reconfiguration is adopted, the average time delay will be decreased to 50% above that of worst performance; the ratio of calling success will be increased to 100%, and the throughput will be increased to 20%.
