A Scheme of Optimal Channel Selection with Channel Evaluation for WSNs

With the rapid development of wireless communication technology, the application of Wireless Sensor Networks becomes more and more widely. However, there may be many wireless devices working together in a small space, causing interference and congestion problems for Wireless Sensor Networks. The frequency hopping technology is widely used in Wireless Sensor Networks with the security becomes more and more important. Channel evaluation is important for adaptive frequency hopping system and the authors proposed a scheme of optimal channel selection with channel evaluation, which can get an accurate and comprehensive channel evaluation by analyzing the Signal-To-Noise Ratio (SNR), loss rate and delay.
