Abstract:
The novel proposed method as a combination of Time Division Multiple Access (TDMA) and Orthogonal Frequency Division Multiple Access (OFDMA) called Orthogonal Frequency Division Most Congested Access First (OFDMCAF) provides spectrum sharing, buffer management and improves the throughput. In this work the power consumed by activating each cognitive method is analyzed in addition to the throughput improvement provided by each method used with OFDMCAF. It is shown at the end of the analysis that activation of each method also decreases the average power consumption even the same routing algorithm is used in all cases.
