Channel sensing in the cognitive radio networks is a very important function to avoid collision with primary users. MAC-layer sensing determines key parameters for channel sensing such as available sensing period and sensing duration. The sensing period and sensing duration affect on the data transmission. The shorter sensing period increases the sensing accuracy and reduces the possibility of packet collision with primary users. However, it can reduce the data transmission time and decrease the system throughput. Therefore, one of the important roles of MAC-layer sensing is to determine the sensing period. In this paper, we evaluate the sensing period to minimize the missing probability and interference probability to the primary users.
