Evaluación del establecimiento de la métrica de enrutamiento WCETT en una red de radio cognitiva

This paper presents an evaluation of the WCETT (Weighted Cumulative Expected Transmission Time) routing metric setup for a cognitive radio network. This metric setup is based on the software application called CRCN (Cognitive Radio Cognitive Network Simulator), which runs over the simulation environment called NS2 (Network Simulator 2). Comparative experiments to assess throughput values were conducted for the following protocols: MAC802.11, MACCON, MACN, Simple and TDMA.
