This paper presents a dynamic frequency allocation method which aims at optimizing the spectrum assignment in cognitive wireless sensor networks used for avionic control applications. The main objective is to improve the frequency utilization of the avionic bands by enabling the sensor nodes (i.e. secondary users or SUs) sharing the spectrum with primary(More)
This paper presents the design of a wireless sensor network architecture suitable for structural health monitoring of air-crafts. The main objective is to improve airplane safety by detecting flutter phenomenon along the wings and communicating this information to the cockpit computer to react before vibration reaches resonance. Therefore, study of network(More)
