中文摘要：

针对移动传感网中的突发事件,提出一种QoS路由协议（EQMR）.EQMR路由协议主要由三个阶段组成：网络初始化、路径发现和建立、数据通信和路径维护.在网络初始化阶段,EQMR协议将网络分成两层：主干网和传输子网.在路径发现与建立阶段,附属骨干节点寻找多条不相交路径中综合代价最小的路径.在数据通信与路径维护阶段,利用ACK确认机制来处理路径选择失败的问题.仿真结果表明,在相等数据发送率的前提下,EQMR路由协议比AODV协议在数据传输成功率、数据延时、网络剩余能量方面均有不同程度的提高.

英文摘要：

As to some disruptive events in mobile sensor network,a QoS routing protocol is proposed（EQMR）.EQMR protocol consists of three phrases： network initialization,route discovery and establishment,data communication and route maintenance.In the first phrase,network is divided into two parts： backbone network,sensing subnet.In the second phrase,related backbone node will find minimum-cost path among multiple disjoint paths.In the third phrase,data transmission and route maintenance are conducted for failure of route selection under ACK confirmation mechanism.Simulation result shows that EQMR protocol can make some improvements for the ratio of successful data delivery,data delay and network residual energy,compared to AODV protocol.
