Abstract 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. Keywords Channel decision Cognitive radio Data transmission Multiple criteria decision making (MCDM) Cognitive radio Multi-objective optimization based on ratio analysis (MOORA)
1 Introduction The invention of cognitive radio network was put forward by Mitola in 1998 and later published by Mitola and Maguire (1999). The dynamic CRN system consists of spectrum sensing and spectrum decision. Spectrum sensing composed of finding the unutilized spectrum holes and also responsible for searching and analyzing the attributes of available spectrum (Akyildiz et al. 2009). In cognitive radio, the distributed spectrum sensing algorithm chooses the spectrum that allows extreme information rate for the cognitive user, while the cooperative algorithm chooses the spectrum which will be advantageous for the overall system throughput (Patel et al. 2018; Mishra et al. 2006; Muthukkumar and Manimegalai 2017). In spectrum decision, spectrum access judgment and spectrum handoff take place.

In the beginning of twenty-first century advances in wireless technologies like Wi-Fi, Bluetooth and mobile telephony achieved an extraordinary focus around the world. Cognitive radio innovation can extensively participate with its essential role in the field of wireless communication and also in an Internet-based applications (Awathankar et al. 2016). To maintain good quality of services these technologies need an efficient transmission spectrum band. With the over increasing demand of spectrum by current and upcoming technologies fixed spectrum allocation (FSA) may face a problem of frequency scarcity (Basnet et al. 2019). According to the re
