High Throughput Spectrum-aware Routing for Cognitive Radio Networks

Abstract—Dynamic spectrum networks enable fast deployment of new wireless technologies by effectively utilizing allocated yet unused wireless spectrum. By sensing and utilizing available wireless channels, cognitive radio devices can provide high throughput, low latency communication. Existing schemes for channel assignment suffer drawbacks in throughput and reachability in the presence of loca...

IMPACT OF TERRAIN AWARE INTERFERENCE MODELING ON THE THROUGHPUT OF COGNITIVE Ka-BAND SATELLITE SYSTEMS

The impact of including the diffraction loss in the interference modeling on the system throughput is assessed in the context of cognitive Ka-band satellite systems. In particular, we focus on the cognitive satellite downlink, where Geostationary (GEO) Fixed Satellite Service (FSS) terminals receive interference from the incumbent Fixed-Service (FS) microwave links. We present numerical results...

interference management in cognitive radio satellite networks based on time and spectrum sensing

in this paper, an interference management for multi-beam satellite network to enhance spectral efficiency is studied. first, a two-satellite for future generation satellite network using cognitive radio technology is provided.this network is composed of a secondary satellite and aprimary satellite where the primary satellite system does not suffer from severe destructive interferences coming fr...
