Abstract

TSCH is a MAC protocol able to provide reliable wireless communication to IoT networks. For applications where mobility is necessary research has shown that TSCH presents a suboptimal performance. One of the main issues is that the time required for a device to join a TSCH network is unpredictable and theoretically has no upper limit. The joining process to a TSCH network can take several minutes in some cases which can ensue significant delay and power overheads. In this paper we examine how TSCH can be adapted to support mobile applications, by improving the joining and re-joining procedure. Relevant information about the network topology is aggregated throughout the network to be utilized during the joining process. The results show that the joining time can be reduced by 50% and the re-joining time by 90%.

以移动性为重点的TSCH网络加入

TSCH是一种MAC协议，能够为物联网网络提供可靠的无线通信。对于需要移动性的应用，研究表明TSCH的性能不是最优的。其中一个主要问题是，设备加入TSCH网络所需的时间是不可预测的，理论上没有上限。在某些情况下，加入TSCH网络的过程可能需要几分钟，这可能会导致严重的延迟和电力开销。在本文中，我们研究如何通过改进连接和重新连接程序来适应TSCH以支持移动应用程序。在加入过程中，将网络拓扑的相关信息聚合到整个网络中，以供使用。结果表明，该方法可使连接时间缩短50%，再连接时间缩短90%。
