To Mitigate with Trusted Channel Selection Using MOORA Algorithm in Cognitive Radio Network

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.
