Time Slotted Channel Hopping (TSCH) is one of the five access behavior technologies defined in the IEEE 802.15.4e standard. Research shows that the wireless sensor network with single dynamic and static channel allocation in TSCH mode has higher performance. The clogging rate results in unnecessary energy waste. Therefore, this paper proposes an adaptive hybrid channel allocation strategy (AHCA) to measure the link quality change of wireless sensor networks in TSCH mode. The strategy estimates the part of the channel quality and determines whether the node wants to transmit on this channel and the optimal channel for node information transmission. According to the change of the amount of information transmitted, the hybrid channel allocation scheme of the dynamic and static channel ratio is adaptively adjusted to reduce the energy consumption of the information transmission process. This article performs experimental simulation on Contiki-NG. The experimental results show that the proposed scheme has shorter transmission time and lower congestion rate than the single dynamic static channel allocation wireless sensor network. The more reasonable and effective measurement, analysis and use of channel resources can fundamentally increase the amount of information transfer in wireless sensor networks per unit time, and thus extend the lifetime of wireless sensor networks.

时隙信道跳频（TSCH）是IEEE 802.15.4e标准中定义的五种访问行为技术之一。研究表明，在TSCH模式下具有单个动态和静态信道分配的无线传感器网络具有更高的性能。堵塞率导致不必要的能量浪费。因此，本文提出了一种自适应混合信道分配策略（AHCA），用于测量TSCH模式下无线传感器网络的链路质量变化。该策略估计一部分信道质量，并确定节点是否要在此信道上传输以及用于节点信息传输的最佳信道。根据传输的信息量的变化，动态和静态信道比的混合信道分配方案被自适应地调整以减少信息传输过程的能量消耗。本文在Contiki-NG上进行实验仿真。实验结果表明，与单动态静态信道分配无线传感器网络相比，该方案传输时间短，拥塞率低。信道资源更合理，更有效的测量，分析和使用可以从根本上增加每单位时间无线传感器网络中信息传输的数量，从而延长无线传感器网络的寿命。实验结果表明，与单动态静态信道分配无线传感器网络相比，该方案传输时间短，拥塞率低。信道资源更合理，更有效的测量，分析和使用可以从根本上增加每单位时间无线传感器网络中信息传输的数量，从而延长无线传感器网络的寿命。实验结果表明，与单动态静态信道分配无线传感器网络相比，该方案传输时间短，拥塞率低。信道资源更合理，更有效的测量，分析和使用可以从根本上增加每单位时间无线传感器网络中信息传输的数量，从而延长无线传感器网络的寿命。
