摘　　要：传统的无线传感器网络(Wireless Sensor Networks,WSNs)路由协议不能很好地适应多媒体数据流的传输.近来,提出了一些无线多媒体传感器网络(Wireless Multimedia Sensor Networks,WMSNs)路由协议.本文首先讲述了WMSNs服务质量保障路由问题及其面临的挑战,从五个方面归纳了传统的WSNs路由协议,在此基础上论述了WMSNs路由协议的QoS需求、设计原则、控制策略及其限制.然后,综述了当前典型的WMSNs服务质量保障控制路由协议,包括各协议的设计目标、核心思想、基本策略、主要内容及其优缺点;在列表比较的基础上,研究了存在的问题和缺陷.最后,指出了WMSNs路由协议研究的开放性问题及其发展方向.It is not suitable to use conventional wireless sensor networks（WSNs） routing protocols to transfer multimedia content such as video and audio streams on wireless multimedia sensor networks（WMSNs）.In order to address those problems,a few new routing protocols were introduced recently.The QoS guarantee routing problem for WMSNs is defined firstly and some facing challenges are discussed in the field.Secondly,after classifying conventional WSNs routing protocols into five groups according to their features,the QoS routing protocol requirements for WMSNs are analyzed,along with their design principles,strategies and limitations.Thirdly,as the main content,the representative QoS routing protocols for WMSNs are surveyed in detail,including their design objective,core idea,basic strategy,main procedure,advantages and drawbacks.Ultimately,open research issues for WMSNs routing protocol are also pointed out.
