摘　　要：针对煤矿井下传感数据业务、语音业务和视频业务对传输时延、传输丢包率和传输能耗方面不同的服务质量需求,提出了一种煤矿井下无线多媒体传感器网络区分服务的路由协议.通过采用线性加权法在传输时延、传输丢包率和传输能耗归一化子服务质量评价函数上设置不同的权重,分别构建3种多媒体业务的总服务质量评价函数.按照传感数据业务最先、语音业务次之和视频业务最后的顺序,通过采用标记法分别利用改进差分进化算法优化3种多媒体业务总服务质量评价函数,来获得3种多媒体业务的传输路径.仿真结果表明：采用所提区分服务的路由协议获得了3条节点不相交路径,实现了煤矿井下3种多媒体业务的区分服务,保障了3种多媒体业务对传输时延、传输丢包率和传输能耗不同的服务质量需求.The services of sensing data,voice and video in underground coal mines require different quality of service（QoS） for transmission delay,packet loss rate and transmission energy consumption.According to the different QoS requirements,a differentiated service routing protocol of wireless multimedia sensor networks（WMSNs） for underground coal mines was proposed.By applying linear weighted method which set different weights in normalized sub QoS evaluation function of transmission delay,packet loss rate and transmission energy consumption,the total QoS evaluation functions of three multimedia services,i.e.the services of sensing data,voice and video,were constructed respectively.According to the sequence,i.e.the sensing data service first,voice service second and video service third,by applying marking method and improved differential evolution algorithm to optimize the total QoS evaluation functions of three multimedia services respectively,the transmission path of three multimedia services were obtained.Simulation results show that three node-disjoint paths are selected with the proposed differentiated service routing protocol which realize differentiated service and guarantee the QoS of transmission delay,packet loss rate and transmission energy consumption for three multimedia services.
