【摘要】 作为传感器网络的高级形式,音视频传感器网络具有广泛的应用前景。本文首先提出一种基于簇的音视频传感器网络体系结构,针对上述体系结构我们设计了一个灵活的、分布于各类音视频传感器节点的中间件—AuViM,并详细描述了中间件中各模块功能以及两种主要工作模式。最后,通过典型应用实例说明了本文设计的AuViM不仅能够为用户提供一种灵活定制QoS的机制,满足用户不同的QoS需求,而且还能很好地支持音视频传感器网络应用的实现。更多还原

【Abstract】 As the advanced form of sensor networks, Audio/video sensor networks can provide rich multimedia information, which doubtlessly benefit a plethora of data hungry applications such as environment monitoring, health care, emergency response, and video security. First, we propose a kind of audio/video sensor networks architecture based on a single hop cluster. Particularly, aiming at the above architecture, we design an Audio/Video sensor networks Middleware, named as AuViM, which deployed on each type of node flexibly. Furthermore, we detail the functions of each middleware and two kinds of working modes. Finally, we describe a typical application case to show that our AuViM not only flexibly meet user’s QoS requirements, but also support the realization of audio/video sensor networks applications effectively.更多还原
