Sensor Localization for Cooperative Spectrum Sensing in the Network with Random Geometric primary

Sensor localization in the sensor network with cooperative spectrum sensing is considered to detect a random geometric primary user (PU). The sensor's detection performance is an important issue which has attracted more attention in recent years. A crucial matter in this scenario is that we do not have any information about the position of primary user. Due to the random location of PU, we studied expectation of detection probability under OR fusion rule assumption and describe approximate theory for sensor's localization in the network. The simulation results confirm our theory on the various scenarios.
