Evaluation of ZigBee Topology Effect on Throughput and End to End Delay Due to Different Transmission Bands for IoT ApplicationsPublished online: Jul 22, 2020
ZigBee is widely used wireless network in Internet of Things (IoT) applications to remotely sensor 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, which is the network and security 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, … etc. The study use Riverbed Modeler to evaluates the effect of ZigBee different topologies on different transmission bands regarding the performance of throughput and end to end delay. The results of the study show which topology should be used at each transmission band to obtain maximum throughput or provides lowest end to end delay, which is case sensitive in some IoT applications that required for example minimum delay.
