Abstract

In this work methods and mathematical algorithms applied to the Cognitive Radio (CR) technology are tested through the  development  of a  CR  simulator applied  to WiFi  and  Long Term  Evolution  (LTE) mobile wireless networks,  structured with each of the four stages of a system CR, using mathematical tools evaluated  in  previous  works  individually.   The implementation of the CR simulator jointly adapts to different algorithms, which are: Singular Value Decomposition (SVD), Coalition Game Theory and Handoff of technologies by Received Signal Strength Indicator (RSSI). The Network Simulator 3 software (NS-3) is used as an environment for the development and execution of a heterogeneous cognitive network based on the created simulator. Results  are obtained,  numerical  data  shown  in  files  for  the SVD methods,  coalition  game and RSSI, these allow to evaluate their  performance comparing them with other theoretical CR algorithms. Validations and comparisons of the detection stage are shown for functional verification of the simulator.
