Abstract

Human activity recognition technology allows a system to detect simple activities by humans, such as standing, sitting, lying, walking, running and others using a camera or sensor. The camera-based human activity recognition system has a lack of adaptability to light so that the accuracy obtained is not good, while wearable sensor-based systems that use multiple sensors cause discomfort when used and battery life problems. In this study a system can be made that can classify simple activities carried out by humans using the MPU6050 sensor which has an accelerometer and gyroscope sensor and uses the k-Nearest Neighbor classification method. Input from this system is the value of the accelerometer and gyroscope sensor readings sent using the NRF24L01 wireless communication module to Arduino Mega as a device that classifies and displays the classification results in Serial Monitor Arduino IDE. In this study the test was carried out using one sensor and two sensors. From the results of the tests performed, obtained the highest accuracy results of 93.75% for systems that use one sensor with sensor placement on the thighs and 96.25% for systems that use two sensors with sensor placement on the thighs and waist. For testing the computation time of the k-Nearest Neighbor method in classifying human activities, the average time taken was 173.6 milliseconds for classification using one sensor and 353.2 milliseconds for classification using two sensors.

Abstract

Software defined network (SDN) is a centralized and flexible network concept compared to traditional networks that exist today. SDN has been developed in the last few years and has been widely implemented, one of which is routing networks. Routing is the process of finding the communication path used to send packets from the sender to the recipient. The implemented routing algorithm is tasked to determine the shortest paths, namely Dijkstra, Bellman-Ford, and Floyd-Warshall algorithms. The three algorithms will be implemented using the Mininet and Ryu controller emulators. For determining the path required the determination of the link or cost weight. Cost in this study is based on the calculation of the reference bandwidth of 1000 Mbps and the bandwidth link that uses three types of capacity quantities, namely 10 Mbps, 100 Mbps, and 1000 Mbps. Testing is done with parameters, namely validation, convergence time, throughput, recovery time and packet loss. Based on the results of validation, the system runs according to the calculation of the manual calculation of each algorithm. In convergence time testing, Dijkstra was superior with an average of 0.0087 seconds compared to Bellman-ford 0.0094 seconds and Floyd-Warshall 0.02025 seconds. In testing the three throughput algorithms do not have far distinction. Based on recovery time testing, the Floyd-Warshall algorithm has faster recovery time than other algorithms. Based on the testing of packet loss Dijkstra is still superior in handling packet loss when sending.
