In cognitive radio network, channel decision is critical assignment to utilize the unused spectrum band as secondary user without interfering with the primary user. Thus different criteria of available spectrum are exploited as per the requirement of secondary user to establish connectivity with the network for data transmission. Here multi-objective optimization based on ratio analysis (MOORA) algorithm is proposed as multiple criteria decision-making method for channel decision in cognitive radio environment. MOORA method acquires contradictory appearances such as criteria and alternative available. A matrix of response of alternatives to the criteria is considered, and ratio analysis is performed to find ranking of available channel. Finally a decision-making problem with different weighted matrix based on user application and criteria is illustrated, and results show that proposed MOORA algorithm outperforms similar other algorithms in terms of diverse criteria features, complexity and practicality.

在认知无线电网络中使用 MOORA 算法通过可信信道选择进行缓解

在认知无线电网络中，信道决策是将未使用的频段用作次要用户而不干扰主要用户的关键分配。因此，根据次要用户的要求，利用可用频谱的不同标准与网络建立连接以进行数据传输。这里提出了基于比率分析（MOORA）算法的多目标优化作为认知无线电环境中信道决策的多准则决策方法。MOORA 方法获得了矛盾的外观，例如标准和可用的替代方案。考虑对标准的备选响应矩阵，并执行比率分析以找到可用信道的排名。
