论文摘要
在许多物联网部署中，远程无线电通信是首选的，因为它避免了多跳无线网络的复杂性。洛拉（Lora）是一种流行的节能无线调制，但其网络底物洛拉万（Lorawan）对用户产生了严重的限制。在本文中，我们介绍并彻底分析了DSME-LORA，这是一种以IEEE 802.15.4 DSME作为MAC层的Lora系统设计。 DSME-Lora提供了无缝的客户到客户通信的优势，而不是纯粹以网关为中心的Lorawan传播。我们通过在流行的Riot操作系统上的全堆栈实现来评估其可行性，在分析随机马尔可夫模型中评估其稳态数据包流，并使用大型网络模拟在大规模通信方案中量化其可扩展性。我们的发现表明，DSME-LORA确实是一种强大的方法，它可以在许多维度上向标准网络层开放，并在许多方面都优于劳拉万。
Long range radio communication is preferred in many IoT deployments as it avoids the complexity of multi-hop wireless networks. LoRa is a popular, energy-efficient wireless modulation but its networking substrate LoRaWAN introduces severe limitations to its users. In this paper, we present and thoroughly analyze DSME-LoRa, a system design of LoRa with IEEE 802.15.4 DSME as a MAC layer. DSME-LoRa offers the advantage of seamless client-to-client communication beyond the pure gateway-centric transmission of LoRaWAN. We evaluate its feasibility via a full-stack implementation on the popular RIOT operating system, assess its steady-state packet flows in an analytical stochastic Markov model, and quantify its scalability in massive communication scenarios using large scale network simulations. Our findings indicate that DSME-LoRa is indeed a powerful approach that opens LoRa to standard network layers and outperforms LoRaWAN in many dimensions.
