论文摘要
我们介绍TDMH(TIME DESICEISTC多跳)协议,这是实时无线网络网络的完整堆栈。 TDMH为应用程序提供了一个面向连接的,有限的延迟通信模型。可以随时创建和破坏点对点数据流。可以选择引入路径冗余以提高可靠性。 TDMH利用了最新的低功率时钟同步和建设性干扰洪水,以构建网络拓扑的不断更新的图表,并在其上使用TDMA Channel访问来映射集中式调度程序数据流。我们意识到TDMH是单一代码库,我们在Omnet ++模拟器和Wandstem无线节点上都运行。结果,我们可以指出,在IEEE 802.15.4物理层上构建时,TDMH尽管可用的带宽有限,但TDMH仍可扩展到100个节点,10个啤酒花。
We present the TDMH (Time Deterministc Multi-Hop) protocol, a complete stack for real-time wireless mesh networks. TDMH offers to applications a connection-oriented, bounded-latency communication model. Point-to-point data streams can be created and destroyed at any time. Path redundancy can be optionally introduced to improve reliability. TDMH exploits state-of-the-art low power clock synchronisation and constructive interference flooding to build a continuously updated graph of the network topology, onto which a centralized scheduler maps data streams using TDMA channel access. We realised TDMH as a unitary codebase, that we ran on both the OMNeT++ simulator and WandStem wireless nodes. As a result we can state that when built atop the IEEE 802.15.4 physical layer, TDMH can scale up to 100 nodes, 10 hops and beyond, despite the limited available bandwidth.
