英文摘要： For the coexistence and optimization problem of Wireless Sensor Networks (WSNs) based on ISM band, a combination method of "top-control" and "remedy afterwards" is proposed to guarantee the network availability and performance stability. This method includes the following original achievements: 1) using the information entropy theory to extract and model the factor features that affect the coexistence performance; 2) dividing the coexistence region based on the adaptive path loss model and the interference coupling decomposition among networks; and 3) cooperative coexistence and optimization method based on the coperative busy signal and shared fitness. These achievements will form a theory and method system for cooperative coexistence and optimization of WSNs on ISM band. In addition, the simulation and experiment platforms will be developed to verify the correctness and effectiveness of the proposed technologies and methods, which will further guide the practical applications.
