An improvement in a simple MAC protocol for cognitive wireless networks

Abstract

Medium Access Control (MAC) is an important aspect of implementing a cognitive radio network. Ghasemi and Razavizadeh proposed a simple, elegant and efficient MAC protocol for cognitive wireless networks [1]. However, the Ghasemi’s algorithm does not consider the quality of the wireless channel in the decision process. In this paper, an improvement in Ghasemi’s algorithm is proposed to consider the behavior of the wireless channel in the decision process.
