Abstract

This paper proposes an optimal packet size search method for multimedia transmission over multi-channel link in multi-class cognitive radio networks. Since the transmission power is limited for users, optimal packet size and corresponding power allocation is needed to maximize expected utility function. The performance is evaluated through the comparison with power-consuming method. Since our proposed method considers not only traffic pattern but also wireless channel characteristics over frequency channel, our simulation results show that the proposed scheme is more energy efficient.

Keywords: cognitive radio networks multi-class traffic multi-channel communications optimal packet size limited transmission power
