Abstract

The Wireless Sensor Network (WSN) has been implemented in several ways to improve quality of living in terms of environment sustainability. WSN in sports such as Taekwondo is applied to validate the points especially in competition. WSN system uses a sensor node (Piezoelectric Sensor) to detect a punch or kick on the body protector of a Taekwondo athlete, then sent by a sink node (ESP8266) to the Web Server. WSN architecture uses a Point to Point Topology that connects two nodes through an Access Point. The WSN Delivery Method uses the Message Queue Telemetry Transport (MQTT) Protocol with the publish / subscribe communication type and the Hypertext Transfer Protocol (HTTP) Protocol with the client-server communication type. The results of the MQTT Protocol test using Round Trip Time (RTT) and Quality of Service (QoS) parameters include Delay, Jitter, Throughput, Packet loss and memory condition parameters, resulting in stable RTT, good QoS delay, stable jitter, good throughput. continues to increase, and 0% packet loss. Then, the HTTP protocol tested the delay and transmission range of 2100 times from the sink node with a distance of 50 m to the access point resulting in an accuracy rate of 100%.
