提出一种基于环形线路的低时延数据收集(LDCR)方法,使sink节点沿环形路线移动,减少部分数据分组等待传输的时间,并在sink节点到达停留点时立即发送HELLO消息,使其通信范围内的传感器节点及时发送数据分组.性能分析结果表明:与现有的sink节点使用往复路线的数据收集方法相比,提出的LDCR方法在数据分组平均端到端时延、吞吐量、分组传送成功率和存储空间占用等方面的性能得到整体提升.
A low delay data collection (LDCR) method based on a ring line is proposed, which moves the sink node along the ring route to reduce the waiting time for some data packets and transmits the HELLO message immediately when the sink node reaches the stay point The sensor nodes in the range send the data packets in time.The performance analysis results show that compared with the existing sink node using the reciprocal routing data collection method, the proposed LDCR method in the data packet average end-to-end delay, throughput, packet transfer The success rate and storage space occupancy and other aspects of the overall performance improvement.
