The tremendous increase in wireless communication networks in the last few decades has lead to spectrum scarcity, which has already set the needs for efficient spectrum utilization. The juvenile and upcoming field of Cognitive Radio (CR) networks is the promises to alleviate the spectrum scarcity problem, by allow devices to share the spectrum with secondary users. This improves the inefficient spectrum utilization in the bands reserved for the licensed users. This paper investigates the use of proposed TCP-friendly protocol for variation in spectrum availability with time and periodic spectrum sensing done by the CR users.
