Spectrum sensing is a key enabling technology of cognitive radio. Reliable detection increases access opportunity to temporarily unused bands and prevents harmful interference to the licensed users. Due to the receiver noise, signal attenuation, and multi-path fading effect, however, it is usually not possible to determine the existence of primary signal with absolute certainty. Without the information...
The problem of optimal (fixed) wireless sensor network (WSN) design for distributed detection of a randomly-located target is addressed. This is an extension of the previous work reported in [1] where the problem was addressed for a one-dimensional (1D) network assuming wireless channels between sensors and the fusion center undergo only the path-loss attenuation. In this paper we consider both one...
