Abstract:

The node access has been paid more attentions in network decision making. An accurate evaluation of wireless channel was investigated. A method based on the process of sensing that is a trade-off between the accuracy of channel sensing and channel idle time, was employed to evaluate the wireless channel. Furthermore, the impact of the sensing parameters including sensing time, sampling frequency on the channel quality was analyzed. An optimal sensing time and sampling frequency was derived to maximize the value of channel quality. Simulations verify the analysis validity.

Key words: autonomic wireless network, channel quality, sampling frequency, sensing time
