Abstract

The development of WSN is getting advance according to the needs of IoT. the amount of data flow in the system will be greater. This massive WSN requires a backbone transmission that has low latency and large bandwidth. Fiber optics is one solution for it. This paper proposes the Hybrid WSN using ZigBee and Fiber Optic (FO) system, and discuss its performance evaluation and characteristics. To obtain information related to system evaluation, system testing is carried out by observing the performance of data transmission. The main system design consists of two ZigBee routers, one ZigBee gateway, two E/O media, an optical fiber cable, and a computer as a display monitor. Data retrieval is done by sending text data and sensor data with 1000ms in interval per-each package data. The indicators analyzed for evaluation are throughput, interval delay per meter, package loss and error. Data results are also compared with the commonly ZigBee to WiFi system. The results obtained from testing the throughput, interval delay per meter, and package loss and error. Based on the results, it can be concluded that a ZigBee-FO hybrid system is implemented, and results better performance in lower latency, and higher throughput than commonly WSN-WiFi systems.
