摘　　要：作为一种全新的信息获取和处理技术,无线多媒体传感器网络在军事、工业、商业、环保中具有广阔的应用前景.无线多媒体传感器网络感知媒体丰富、数据量大,处理任务复杂等显著特点,使其QoS保障问题的研究极具挑战性.本文就此问题,总结了无线多媒体传感器网络的QoS需求及其当前所面临的技术挑战.从MAC层、网络层、传输层、应用层、交叉层以及中间件六个方面,着重描述了无线多媒体传感器网络QoS保障的国内外研究进展.最后,分析了当前亟待解决的问题以及未来的研究趋势.Wireless multimedia sensor network is a novel information acquiring and processing technology. Its potential applications span a wide spectrum from military to industrial, from commercial to environmental monitoring. The distinct features of wireless multimedia sensor networks, such as various media category, great data amount, complex processing task, make the issue of QoS guarantee in wireless multimedia sensor networks is challenging. This paper explores this issue, and discusses the QoS requirements and technical challenges faced in this field. In particular, this paper summarizes the current research progresses from six aspects： MAC layer, network layer, transport layer, application layer, cross layer and middieware. Finally, the problems to be solved and the research trend are also pointed out.
