Cognitive radio sensor networks (CRSNs) exploit the cognitive radio concept to allow wireless sensor networks to dynamically access the available channels. However, existing channel sensing techniques developed for cognitive radios are not applicable to the energy-constrained sensor nodes. In this paper, we present two energy-efficient cooperation schemes(More)
Incorporating the cognitive radio (CR) concept to cognitive radio wireless sensor networks (CRSNs) allows wireless sensor networks (WSNs) to overcome the spectrum scarcity problem and dynamically access the available channels. However, existing CR channel sensing techniques are not efficient to the energy-constrained WSNs nodes. In this paper, we present(More)
This study aimed to determine the aerosolization behavior of a nanodispersion of budesonide, prepared using microfluidic reactors. The size and morphology of budesonide nanoparticles were characterized by photon correlation spectroscopy (PCS) and transmission electron microscopy (TEM). Processing/formulation parameters for formation of the nanoparticles(More)
