Thesis Proposal Csc 2015 Optimization of Spectrum Sensing Mechanisms for Hybrid Satellite/terrestrial Sensor Networks

Context: in many sensor systems, the information collected by sensors is transmitted to ground receivers via a satellite link: emergency communication systems, control and acquisition systems [1]. When the sensor network is a cognitive network, secondary sensors can use network resources when primary sensors, i.e., high priority sensors, do not use them. One of the major concerns in this context is the allocation of the resources between primary and secondary sensors. We focus here on opportunistic spectrum access (OSA) schemes where secondary sensors scan the wireless channel and
