On the Design of Location-Invariant Sensing Performance for Secondary Users

Executive Summary

In this paper, the authors consider the setting of one-shot spectrum hole detection for a uniformly distributed secondary network under fading and path loss. They separate the sensors that are used to detect spectral holes from the secondary transmitters, thus allowing each secondary transmitter to benefit from the decisions of multiple (shared) sensors. The detection performance of the sensors varies with the distance from the primary transmitter. Thus a secondary listens to different average number of sensors as it moves around the cell, making the fusion rule complicated.
