摘要

低功耗和有损网络(LLN)用于许多物联网(IoT)应用。针对工业物联网的需求,IEEE指定了时隙信道跳频(TSCH)媒体访问控制(MAC)。TSCH支持不可靠无线环境下的确定性通信,并平衡能量、带宽和延迟。此外,最小6TiSCH配置定义了低功耗和有损网络(RPL)的路由协议,目标函数为0 (OF0)。来自RPL操作的固有因素,如加入过程、父节点交换和涓流定时器波动,可能会引入开销并使控制消息使网络过载。应用程序和RPL控制数据可能会导致不可预测的网络瓶颈,从而可能导致网络不稳定。因此,稳定的RPL操作有助于健康的TSCH操作。在本文中,我们探讨了TSCH MAC和RPL指标,以确定导致性能下降的因素,并指定指标来预测网络紊乱,以提高工业物联网的可靠性。TSCH调度函数可以使用识别的方面来预测干扰,主动分配适当数量的单元,并避免网络拥塞。

Towards the support of Industrial IoT applications with TSCH
Low-power and Lossy Networks (LLN) are utilised for numerous Internet of Things (IoT) applications. IEEE has specified the Time-slotted Channel Hopping (TSCH) Media Access Control (MAC) to target the needs of Industrial IoT. TSCH supports deterministic communications over unreliable wireless environments and balances energy, bandwidth and latency. Furthermore, the Minimal 6TiSCH configuration defined Routing Protocol for Low power and Lossy networks (RPL) with the Objective Function 0 (OF0). Inherent factors from RPL operation, such as joining procedure, parent switching, and trickle timer fluctuations, may introduce overhead and overload the network with control messages. The application and RPL control data may lead to an unpredicted networking bottleneck, potentially causing network instability. Hence, a stable RPL operation contributes to a healthy TSCH operation. In this paper, we explore TSCH MAC and RPL metrics to identify factors that lead to performance degradation and specify indicators to anticipate network disorders towards increasing Industrial IoT reliability. A TSCH Schedule Function might employ the identified aspects to foresee disturbances, proactively allocate the proper amount of cells, and avoid networking congestion.
