Sebagai salah satu teknologi capaian spektrum dinamik, "teknologi radio kognitif," yang bertujuan untuk meningkatkan kecekapan spektrum, telah dikaji. Dalam rangkaian radio kognitif, setiap nod mengenali keadaan radio, dan menurut mereka, mengoptimumkan laluan komunikasi wayarlesnya. Sistem radio kognitif mengintegrasikan sistem wayarles heterogen bukan sahaja dengan menukarnya tetapi juga mengagregat dan menggunakannya secara serentak. Kawalan adaptif penggunaan tukar ganti dan penggunaan serentak pelbagai sistem wayarles akan menawarkan komunikasi wayarles yang stabil dan fleksibel. Dalam kertas kerja ini, kami mencadangkan skim kawalan laluan trafik adaptif yang menyediakan perkhidmatan berkualiti tinggi (QoS) untuk teknologi radio kognitif, dan mengkaji prestasi skim yang dicadangkan melalui ujian lapangan dan simulasi komputer. Keputusan ujian lapangan menunjukkan bahawa kawalan laluan adaptif mengikut keadaan radio meningkatkan daya pemprosesan IP pengguna sebanyak lebih daripada 20% dan mengurangkan kelewatan sehala kepada kurang daripada 1/6 dengan penggunaan serentak IEEE802.16 dan IEEE802.11. XNUMX media tanpa wayar. Selain itu, hasil simulasi dengan mengandaikan beratus-ratus terminal mudah alih mendedahkan bahawa bilangan pengguna yang menerima QoS perkhidmatan suara melalui IP (VoIP) yang diperlukan dan jumlah pemprosesan rangkaian pengguna FTP meningkat lebih daripada dua kali pada masa yang sama dengan algoritma yang dicadangkan. Skim kawalan laluan trafik adaptif yang dicadangkan boleh meningkatkan prestasi teknologi radio kognitif dengan menyediakan laluan komunikasi yang sesuai untuk pelbagai aplikasi untuk memenuhi QoS yang diperlukan.

Abstract: As one of the dynamic spectrum access technologies, "cognitive radio technology," which aims to improve the spectrum efficiency, has been studied. In cognitive radio networks, each node recognizes radio conditions, and according to them, optimizes its wireless communication routes. Cognitive radio systems integrate the heterogeneous wireless systems not only by switching over them but also aggregating and utilizing them simultaneously. The adaptive control of switchover use and concurrent use of various wireless systems will offer a stable and flexible wireless communication. In this paper, we propose the adaptive traffic route control scheme that provides high quality of service (QoS) for cognitive radio technology, and examine the performance of the proposed scheme through the field trials and computer simulations. The results of field trials show that the adaptive route control according to the radio conditions improves the user IP throughput by more than 20% and reduce the one-way delay to less than 1/6 with the concurrent use of IEEE802.16 and IEEE802.11 wireless media. Moreover, the simulation results assuming hundreds of mobile terminals reveal that the number of users receiving the required QoS of voice over IP (VoIP) service and the total network throughput of FTP users increase by more than twice at the same time with the proposed algorithm. The proposed adaptive traffic route control scheme can enhance the performances of the cognitive radio technologies by providing the appropriate communication routes for various applications to satisfy their required QoS.
