摘　　要：分析造成WSN（无线传感器网络）能量消耗的主要原因,总结无线传感器网络MAC（媒体访问控制）协议的节能技术并进行分类,研究采用不同节能技术的典型MAC协议,并进行能效、特点和应用范围的比较。最后,展望无线传感器网络MAC协议节能技术的进一步研究策略和发展趋势。＂Learning-society＂ is a lifelong education society which takes lifelong education as the foundation, learners as the centre, and everyone can learn lifelong. Self taught examination is a guarantee from the system, environment, organization and other aspects of the provision to receive higher education equity and achieve the social members＇ continuing education requirements. Self-taught examination is basically consistent with the ＂learning-society＂ features in the form of higher education. This article from the perspective of the examination management mechanism, discuss the self-taught exam orientation and reform which adapt to ＂ learning-society＂ construction.
