Abstract

Wireless Sensor Network is a technology used in obtaining data from physical conditions or environmental conditions with the help of sensors. Wireless Sensor Network consists of several nodes that will transmit data on the Gateway node. Wireless Sensor Network communication requires the same Channel to connect between nodes. Problems with the Wireless Sensor Network if the area is monitored widely and the nodehas multi- channels will require a lot of Gateway nodes according to the number of channels. Wireless Sensor Network communication like this is less concise and requires extra funds. Based on the problems mentioned in this research applied Wireless Sensor Network communication with multi-channel. Multi-channel will improve the performance of data transmission so that on the Gateway nodethere are several channels for communication with the node. The method in this study is another SPI (Serial Periperal Interface) on the node, I2C on the Gateway node. The results of Wireless Sensor Network communication with Multi-Channel method can improve the delivery and data reception performance. The node address specification has an important role in multi-channel communication to perform channel switches in receiving data on the server. Data obtained by the server successfully received at the same time, but it takes approximately 2 - 4 seconds of synchronization at the beginning communication.

Abstract

It's a common sense that the railways as a means of transportation is needed by all kind of people. In previous studies, GPS train tracking is done with XML RPC technology. For each train that will going to be tracked, it's being installed with an Android based mobile device that comes with an application which will sends GPS's signals that contains position data at a certain time's interval to a server via a webservice mechanism by utilizing XML RPC technology. The author believes, the method of publish/subscribe can be used to replace the method in the previous studies without having a result that inferior to XML RPC client-server. This study uses MQTT protocol (MQ Telemetry Transport) and Mosquitto broker to implement publish/subscribe architecture. Finally, it can be concluded that the quality of the produced delay is in compliance with the author's hypothesis, that the delays required to deliver messages generated by the publish/subscribe protocol are smaller than XML RPC protocol's delays, as has been shown in the preliminary research, where the resulting delay of XML RPC protocol are always greater than MQTT. This is being proved using 2 testing scenarios for each protocol, these are one-to-many testing and many-to-one testing.

Abstract

Virtualization is the process of creating forms in virtual versions of operating systems, networks and others that can run applications like physical devices. Resources in virtualization become an important factor to support server performance. Sometimes resources are not fully utilized when resource allocation remains. As a result, when the server requires more resources, unused memory allocations can not be used. With memory allocation, the system can manage memory usage to maintain and improve server performance that can sometimes change. Application of memory allocation can be facilitated by algorithm and k-means regression method to predict the use of memory resources. To that end, the authors have implemented a dynamic memory allocation system on computer-based k-means clustering system. From the test results, the system is able to make changes in the form of upgrades and downgrades with the help of tools Apache Jmeter with time 2.5 seconds. Based on the results of tests that have been done, hypervisor successfully upgraded at 36.5699 seconds from 1 GB to 2 GB. Then second to 153.1348 hypervisor upgrade again from 2 GB to 4 GB. After the request to the server stops, the hypervisor downgrades the seconds to 611.709 from 4 GB to 2 GB then downgrade again in seconds to 624.4994 from 2 GB to 1 GB.
