Abstract

Obstructive Sleep Apnea is a condition in which breathing stops momentarily during sleep and repeats several times. If this disorder is not treated further, it can cause complications in the form of lack of sleep, fatigue and eye problems. For now, sleep apnea examination can only be checked in a hospital and is expensive. Therefore, in this study a system for detecting obstructive sleep apnea was created which did not require too much money. The tools to be used are the Arduino Uno microcontroller as a place for the system program, the ECG AD8232 sensor to detect electrical activity in the heart which is attached to the chest using 3 electrodes, and a 16x2 LCD to display the final result. This study uses the Naive Bayes classification in classifying the electrical activity of the heart. The features in the classification of the naive Bayes method are the QT Interval and the PR Interval, the results of which will be displayed on the LCD in the form of "Normal" or "Sleep Apnea". There were 24 test data taken and 48 training data used in the Naive Bayes classification test. The results of the accuracy test using Naive Bayes were 87.5%. And the results of computational time testing were carried out 24 times with an average value of 1,044.2083 ms.

Abstract

Self-configure is unique to the MANET network, where the network is formed from independent nodes that communicate each other. In MANET, there is a standardized route determination mechanism in sending data packets called the routing protocol. Nodes in a MANET network require energy to communicate, while energy on nodes is limited. Therefore, when testing the network performance, energy consumption is a factor that needs to be taken into account. Temporally Ordered Routing Algorithm (TORA) is a routing protocol that can operate on MANET networks. This study aims to calculate the energy consumption of the MANET network by implementing the TORA protocol. The simulation is carried out with a scenario of increasing the number of nodes from 30, 50 to 70 in an area of ​​1000m x 1000m with an initial energy of 1000 Joules and a simulation time of 100 seconds. This scenario is performed on two different mobility models, namely the fixed grid model and the random waypoint model. From the simulation data, the average value of energy consumption in the fixed grid model for 30 nodes is 65.374 Joule, 50 nodes are 62.262 Joules and 70 nodes are 61.549 Joules. Whereas the random waypoint model for 30 nodes is 62.807 Joules, 50 nodes are 55.808 Joules and 70 nodes are 54.388 Joules. With the scenario of increasing the number of nodes there is a decrease in the average value of energy consumption in the two mobility models, this is due to the multi-route mechanism in the TORA.

Abstract

Monitoring system is common this time. However, security system needs attention. Because if unauthorized people controls the data from monitoring system, it can endanger owner of monitoring system. Aspect that need to guarded in monitoring system is confidentiality. SPECK algorithm can fulfill confidentiality security and has advantage of low specifications system. SPECK algorithm is implemented in monitoring system on manager and agent when sending and receiving data. Tests includes test vectors, performance, sniffing attacks and known plaintext attacks. Time for monitoring system process encryption has an average 1,780.738 ms on Raspberry Pi 0 W, 799.173 ms on Raspberry Pi 2 and 481.7921 ms on Raspberry Pi 3. Time to process decryption has an average 2,007.717 ms on Raspberry Pi 0 W, 880.4057 ms on Raspberry Pi 2 and 508.9488 ms on Raspberry Pi 3. Data amount before and after encryption is 524 byte in resource, network and disk scenarios. Results of test vector test is same as the SPECK paper so they declared successful. Sniffing test also successful because when checked using Wireshark application, contents of the packet is ciphertext. In known plaintext attack test, the test was successful because the resulting ciphertext failed to decrypt by brute force.
