Dynamic allocation system and method for avoiding the channel frequency interference

Channel dynamic allocation method for avoiding the interference are ubiquitous sensor network (Ubiquitous Sensor Network, USN) and WiFi (Wireless Fidelity, WiFi) to when the power in the channel dynamic allocation system using at the same time applying step in which the USN module and WiFi is activated and, USN module sends a message to the peripheral USN Emmett and the USN frequency channel receives the interference to the WiFi frequency channel by analyzing the step of identifying the USN Mott number information, WiFi frequency channel and USN frequency channel based on the response whether a step of detecting, WiFi module to search for nearby WiFi communication channel near to identify the channel scan information of the WiFi access points, and detects the remaining change USN frequency channels other than the USN frequency channel receives the interference corresponding to the channel scan information step and change to be transmitted to the USN Mott USN USN frequency of the frequency channel to the surrounding USN Emmett And a step of controlling to change the channel to transmit data.
