In this paper, we propose a new approach which uses CR for improving realtimeapplication performance related to only one cognitive radio mobile terminal (CRMT). We also present a synthesis of research relating to dynamic spectrum allocationand sharing in the context of CR networks using multi-agent systems. In our future work, we will seek to improvereal-time application performance related to many CRMT.frcognitive resourceradioresourceArticle
