Abstract: Abstract Spectrum-Map-empowered Opportunistic Routing (SMOR) systems have been created to accomplish dynamic opportunistic links and dependable end-to-end transmission in Cognitive radio ad-hoc networks (CRAHNs). However, only delay has been considered in the mathematical analysis of SMOR in both regular and large-scale networks which results in degraded routing performance. This work examines the transmission delay and the network throughput is evaluated and the relationship between them to develop modified SMOR algorithm by incorporating the concept of acknowledgment (ACK) for each node in the routing link. The Modified SMOR for regular CRAHN utilizes Diffusion approximation based Markov chain modeling and queuing network theory while for large-scale CRAHN utilizes sparse approximation based stochastic geometry and queuing network theory for examining delay and throughput. The Modified SMOR-1 and Modified SMOR-2 are proposed for satisfying the opportunistic routing mechanisms. The experimental results illustrate that the modified SMOR improves the reliability and dynamic routing performance.
