In this Paper, we had summed up the current problems of the wireless sensor network security based on the research of others. And with our research results, we had gave out a access model of trust-based trade-off mechanism for wireless sensor network. We also described the relevant theory, experimental methods and conclusions of the modal in detail. We hope to provide a new idea for wireless sensor network security research.%在其他人的研究基础上,总结出了无线传感器网络当前存在的安全问题,并根据自身的研究成果,提出了一种基于信任度权衡的无线传感器网络访问机制模型,详细阐述了该模型的相关原理、实验方法及结论,为无线传感器网络安全研究提供了一种新思路.
