摘要
传统 802.15.4存在着单信道、不支持多跳等问题，而工业互联网需要可靠性、准确性，故引入了802.15.4e 三大增强模式，分别为TSCH、DSME、LLDN，对于大规模多跳Mesh、工业监测、周期性数据采集场景，DSME协议相比TSCH、LLDN 协议更具适配性，因此测定DSME协议的吞吐量、丢包率等关键性能，对该类场景的网络部署与优化至关重要。现有研究中已存在用于评估 TSCH 协议性能的马尔可夫队列模型，考虑到DSME与TSCH 协议结构具有一定相似性，本文以现有评估TSCH性能的模型为基础，针对两者在时隙结构、收发机制、GTS调度等核心维度的差异，提出三大改进部分：时隙结构、收发机制、状态与马尔可夫适配，构建出一种可精确评估DSME协议各项性能的马尔可夫队列模型，为DSME协议在工业多跳场景中的性能分析提供理论支撑。
Abstract
Traditional 802.15.4 suffers from issues such as a single channel and lack of multi-hop support. In contrast, industrial internet requires high reliability and accuracy, leading to the introduction of the three enhanced modes of 802.15.4e: TSCH, DSME, and LLDN. For large-scale multi-hop mesh networks, industrial monitoring, and periodic data collection scenarios, the DSME protocol is more suitable than TSCH and LLDN. Therefore, measuring key performance metrics of the DSME protocol, such as throughput and packet loss rate, is crucial for network deployment and optimization in such scenarios. Existing research has proposed a Markov queueing model for evaluating the performance of the TSCH protocol. Considering the structural similarities between DSME and TSCH, this paper builds upon the existing TSCH performance evaluation model and proposes three major improvements to address the core differences between the two protocols in terms of time slot structure, transceiver mechanism, and GTS scheduling. These improvements include time slot structure, transceiver mechanism, and state and Markov adaptation, thereby constructing a Markov queueing model that can accurately evaluate various performance metrics of the DSME protocol. This model provides theoretical support for performance analysis of the DSME protocol in industrial multi-hop scenarios.关键词
