提出了一种基于自适应传输距离的拓扑控制（ATRTC）方案，以降低时延和提高对时延和损耗敏感的无线传感器网络数据采集的时延和可靠性。ATRTC方案的核心思想是扩大传输范围，加快数据采集速度，提高数据采集的可靠性。本文的主要创新点有：(1)提出了一种自适应传输距离调整方法，提高了数据采集的可靠性，减少了数据采集的延迟。传输范围的扩大可以让更多的接收方接收到数据包，从而提高数据传输的可靠性。另一方面，通过扩展传输范围，数据包可以以更少的跳数传输到sink。从而减少了数据采集的延迟，提高了数据传输的可靠性。扩大传输范围会消耗更多的能量。幸运的是，我们发现了网络能耗的不平衡。当网络死亡时，仍有大量的能量剩余。本文提出的ATRTC方案可以充分利用剩余能量来扩展节点的传输范围。由于传输范围的扩大，网络中的节点形成多条路径进行数据采集到汇聚节点。因此，减少了近汇聚节点接收和发送的数据量，降低了近汇聚节点的能耗，延长了网络的生存时间。(2)根据本文的分析，与CTPR方案相比，ATRTC方案最大能耗降低9%，网络寿命提高10%，数据采集可靠性提高7.3%，网络数据采集时间减少23%。
An Adaptive Transmission Range Based Topology Control (ATRTC) scheme is proposed to reduce delay and improve reliability for data collection in delay and loss sensitive wireless sensor network. The core idea of the ATRTC scheme is to extend the transmission range to speed up data collection and improve the reliability of data collection. The main innovations of our work are as follows: (1) an adaptive transmission range adjustment method is proposed to improve data collection reliability and reduce data collection delay. The expansion of the transmission range will allow the data packet to be received by more receivers, thus improving the reliability of data transmission. On the other hand, by extending the transmission range, data packets can be transmitted to the sink with fewer hops. Thereby the delay of data collection is reduced and the reliability of data transmission is improved. Extending the transmission range will consume more energy. Fortunately, we found the imbalanced energy consumption of the network. There is a large amount of energy remains when the network died. ATRTC scheme proposed in this paper can make full use of the residual energy to extend the transmission range of nodes. Because of the expansion of transmission range, nodes in the network form multiple paths for data collection to the sink node. Therefore, the volume of data received and sent by the near-sink nodes is reduced, the energy consumption of the near-sink nodes is reduced, and the network lifetime is increased as well. (2) According to the analysis in this paper, compared with the CTPR scheme, the ATRTC scheme reduces the maximum energy consumption by 9%, increases the network lifetime by 10%, increases the data collection reliability by 7.3%, and reduces the network data collection time by 23%.
