这里研究了一种能满足服务质量(QoS,Quality of Service)需求的能量有效的多路径多速率路由算法EAMM,该算法能结合节点地理位置、延迟时间、丢包率和剩余能量信息,选择符合要求的若干条路径,满足数据传输的可靠性和实时性要求,为不同应用的数据提供不同等级的可靠性和实时性传输质量。仿真结果显示,该算法不仅能保证各等级可靠性和实时性的数据传输,还能均衡网络的能量消耗,延长了网络的生存时间。 In this paper, we study an energy efficient multi-path multi-rate routing algorithm EAMM that can meet the quality of service (QoS) requirements. This algorithm can be combined with the node geographical location, delay time, packet loss rate and residual energy information, The required number of paths to meet the reliability of data transmission and real-time requirements for different applications provide different levels of data reliability and real-time transmission quality. The simulation results show that this algorithm can not only ensure the reliability and real-time data transmission at all levels, but also balance the energy consumption of the network and prolong the lifetime of the network.
