Protokol Kawalan Akses Sederhana (MAC) teragih mudah untuk rangkaian wayarles kognitif dicadangkan. Adalah diandaikan bahawa rangkaian berslot, spektrum dibahagikan kepada beberapa saluran, dan model trafik agregat statistik rangkaian utama pada setiap saluran diberikan oleh pembolehubah rawak Bernoulli bebas. Objektif MAC kognitif adalah untuk memaksimumkan eksploitasi slot masa terbiar saluran. Pengguna kognitif boleh mencapai matlamat ini dengan melompat yang sesuai antara saluran pada setiap peringkat keputusan. Protokol yang dicadangkan adalah berdasarkan peraturan kegagalan terkecil yang digunakan oleh setiap pengguna secara bebas. Menggunakan peraturan ini, pada setiap peringkat keputusan, saluran dengan bilangan perlanggaran yang direkodkan paling sedikit dengan pengguna utama dan pengguna kognitif lain dipilih untuk eksploitasi. Prestasi protokol yang dicadangkan untuk berbilang pengguna kognitif disiasat secara analitikal dan disahkan melalui simulasi. Ia ditunjukkan bahawa apabila bilangan pengguna meningkat, keputusan pengguna di bawah protokol ini hampir kepada keputusan optimum untuk memaksimumkan penggunaannya sendiri. Di samping itu, untuk meningkatkan penggunaan peluang dalam kes sejumlah besar pengguna kognitif, lanjutan kepada protokol MAC yang dicadangkan dibentangkan dan dinilai melalui simulasi.

Abstract: A simple distributed Medium Access Control (MAC) protocol for cognitive wireless networks is proposed. It is assumed that the network is slotted, the spectrum is divided into a number of channels, and the primary network statistical aggregate traffic model on each channel is given by independent Bernoulli random variables. The objective of the cognitive MAC is to maximize the exploitation of the channels idle time slots. The cognitive users can achieve this aim by appropriate hopping between the channels at each decision stage. The proposed protocol is based on the rule of least failures that is deployed by each user independently. Using this rule, at each decision stage, a channel with the least number of recorded collisions with the primary and other cognitive users is selected for exploitation. The performance of the proposed protocol for multiple cognitive users is investigated analytically and verified by simulation. It is shown that as the number of users increases the user decision under this protocol comes close to the optimum decision to maximize its own utilization. In addition, to improve opportunity utilization in the case of a large number of cognitive users, an extension to the proposed MAC protocol is presented and evaluated by simulation.
