COGNITIVE RADIO BASED VEHICULAR COMMUNICATION IN A
no vote
Cognitive network communication is a promising
technique for efficient utilization of scarce radio resources and guaranteeing
quality of services (QoS) in industrial wireless networks. This project is
aimed at introducing network heterogeneity to the existing WSN in an effort to
reduce the problem of over crowdedness of wireless devices in the ISM band. For
heterogeneity to be of an advantage for process monitoring in industry there is
need to incorporate cognitive radio technology to the sensors so as to provide
Dynamic Spectrum Access (DSA). In this project we study the applicability of
cognitive radios in the harsh industrial environment characterised by multiple
obstacles, interference produced by heavy machinery and interference caused by
other communicating devices. The evaluation is conducted in the ISM band (2.4
GHz), cellular band (1.9 GHz) and Wi-Fi band (5GHz). Opt
