Abstract

ZigBee is widely used in wireless network in Internet of Things (IoT) applications to remotely sensing and automation due to its unique characteristics compared to other wireless networks. According to ZigBee classification of IEEE 802.15.4 standard, the network consists of four layers. The ZigBee topology is represented in second layer. Furthermore, the ZigBee topology consists of three topologies, star, tree and mesh. Also there are many transmission bands allowed in physical layer, such as 2.4 GHz, 915 MHz, 868 MHz. The aim of this paper is to evaluate the effect of ZigBee topologies on End to End delay and throughput for different transmission bands. Riverbed Modeler is used to simulate multiple ZigBee proposed scenarios and collect the results. The results of the study recommend which topology should be used at each transmission band to provide lowest End to End delay or obtain maximum throughput, which is case sensitive in some IoT applications that required for example minimum delay time or sending high amount of data.

物联网应用中不同传输频带对ZigBee拓扑结构吞吐量和端到端延迟影响的评估

ZigBee由于其与其他无线网络相比的独特特性，被广泛应用于物联网（IoT）应用中的无线网络中，用于遥感和自动化。根据IEEE802.15.4标准的ZigBee分类，该网络由四层组成。ZigBee拓扑结构在第二层中表示。此外，ZigBee拓扑结构由三种拓扑结构组成，星形、树状和网状。此外，在物理层中允许许多传输频带，例如2.4GHz、915MHz、868MHz。本文的目的是评估ZigBee拓扑结构对不同传输频带的端到端延迟和吞吐量的影响。RiverbedModeler用于模拟ZigBee提出的多个场景并收集结果。研究结果建议在每个传输频带使用哪种拓扑结构来提供最低的端到端延迟或获得最大吞吐量，这在一些需要足够的最小延迟时间或发送大量数据的物联网应用中是区分大小写的。
