Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: In this article,  consider a cognitive radio (CR) relay network where one source secondary user (SU) communicates with its corresponding destination SU with the help of relay SUs. Conventionally, equal bandwidth and/or por are allocated to each relay SU, which may not be efficient for the CR with limited bandwidth and por. Therefore, this article presents bandwidth and por allocation with amplify-and-forward (AF) or decode-and-forward (DF) relaying protocol to (1) maximize the sum network throughput; (2) minimize the total transmit por of the CR network with considering the fairness of por drain of relay SUs; (3) maximize the energy efficiency of the CR network. It is shown that DF relaying protocol can achieve better performance when the decoding rate constraint is not considered. In contrast, when considering the decoding rate constraint in DF relaying protocol,  propose the hybrid relaying protocol that combines AF and DF relaying protocols.  formulate the joint bandwidth and por allocation problem with hybrid relaying protocol to maximize the sum network throughput. A greedy algorithm is developed to solve the joint optimization problem, which has much less computational complexity. It is shown that the greedy algorithm has comparable performance to the exhaustive search algorithm. Finally, numerical results are provided to endorse our proposed algorithms.
