摘　　要：随着微机电、无线通信等关键支撑技术研究的持续发展,无线传感器网络的研究也进一步深化。无线传感器网络适用的领域越来越广,有人适时提出多媒体无线传感器网络的概念,以满足人们在传感器网络平台下对图像、语音,甚至视频数据等信息传输的需求。如何实现无线传感器网络在多种应用环境及同一环境下多工作模式的智能化转换,软件无线电技术无疑是一种较好选择。就软件无线电技术引入传感器网络进行一些探讨,对PHY层MAC层的技术进行了研究。最后,展示了一个简单的传感器网络软件无线电演示平台。Developing with micro- mechanical and micro - electric tecnologies and wireless comminications, the study on wireless sensor networks has been deepened. Wireless sensor networks have been used in more and more fields. The multimedia wireless sensor network is proposed to satisfy the demand for transmitting image and voice, even video over wireless sensor network. No doubt, software radio is a way to achieve the transmission between multi - surroundings or multi - working modes in wireless sensor network. This paper introduces software radio into wireless sensor network, discusses on some technologies of MAC and PHY. The demonstrating system of a simple wireless sensor network based on software radio is showed.
