摘　　要：嵌入式设备部署过程中选择合适的传感器节点位置和连接方式,有助于降低网络能耗,提高工作效率。为此,提出面向嵌入式设备部署的无线传感网络数据采集加速方法。以优化无线传感网络数据采集性能为目的,设计嵌入式设备部署星型拓扑。从拓扑中选取传感器节点完成采集任务,并从无线传感网络传输速率和传输延迟两方面更新无线传感网络传输协议参数。利用直线斜率与误差阈值尺度关系获取感知数据,设计提速流程实现网络数据采集加速。仿真结果表明,该方法采集时延小于200 ms,最大采集覆盖范围是50 m^(2),平均能量消耗低于920 mJ,丢包率低于12%。证明了所提方法能够提高网络数据采集速度,减少资源消耗。Choosing appropriate node locations and connection methods during the deployment process of embedded devices can help re-duce network energy consumption and improve work efficiency.To this end,a wireless sensor network data acquisition acceleration method for embedded device deployment is proposed.An embedded device deployment star topology is designed with the aim of optimi-zing the data collection performance of wireless sensor networks.Sensor nodes are selected from the topology to complete the collection task,and the wireless sensor network transmission protocol parameters are updated from two aspects,i.e.,transmission rate and transmis-sion delay.The relationship between the slope of the straight line and the error threshold scale is utilized to obtain perceptual data,and an acceleration process is designed to accelerate network data collection.The simulation results show that the acquisition delay of this method is less than 200 ms,the maximum acquisition coverage is 50 m^(2),the average energy consumption is less than 920 mJ,and the packet loss rate is less than 12%.It has been proven that the proposed method can improve the speed of network data collection and re-duce resource consumption.
