This paper introduces an analytical uplink modeling for cognitive wireless sensor network (CWSN). For such network, we derive the outage probability, throughput, affected area, and delay‐sensitive area spectral efficiency (DASE). In addition, we investigate the DASE maximization problem and also obtain an optimal solution of transmission power and code rate. Finally, numerical results demonstrate that DASE is maximized for optimal transmission power compared with code rate.
