英文摘要： Recent research and tests show that interference has significant impact on performance of cognitive wireless mesh networks, and the intrinsic relationship between them is not clear. However, existed work only concentrates on physical layer and one-hop networks, and there is an urgent requirement for effective methods to improve the performance of cognitive wireless mesh networks with interference. Focusing on the issue of performance deterioration of cognitive wireless mesh networks with interference, this project will explore the key factors of affecting the protocol performance and traffic performance, reveal the essential relationship among interferecne, degree of freedom of antenna configuration, frequency division multiplexing of channel configuration, space division multiplexing of power configuration, and concentrate on performance optimization of cognitive wireless mesh networks based on interference tolerance and interference cancellation, including: employing hierarchical and cross-layer design method, formulate performance model based on interference temperature; combined with adaptive interference temperature-aware and scheduling techniques, seek interference tolerate-aware throughput optimization techniques; based on successive interference cancellation and optimization, explore resource reservatio
