This is a flexible framework that can be used to generate synthetic output of sensor networks. Nearly all aspects of it are modular and easily expandable, so it could also be used to generate arbitrary time series data.
It was originally written as part of my bachelor's thesis. The thesis can be found on my website.
This project uses Gradle to manage dependencies and build the application.
To build a stand-alone jar file run task fullJar in subproject 'standalone'.
java -jar <application> [<arguments>]
The following command-line arguments are available:
--help, -h
Prints a list of available commands.
--outputsize <long>, -n <long>
The amount of output that should be generated. Default: 1000
--output <string>, -o <string>
Sets the file the output will be written to. Default: "output.txt"
--buffersize <long>
Defines how many lines should be stored in the buffer at a time. Default: 500
--save, -s
Write the configuration to a file.
--load, -l
Load the configuration from a file.
--settinglocation <string>
The file to use for configuration reads/writes. Default: "settings.yml"
--createconfigonly
Only writes the config file and exits.
The settings file is generated using YamlBeans. It is written in yaml.
Each output object is represented as a single line in the output file. An object line looks like this, depending on
settings
and available data types:
0984 currentValue:34.055492,precision:0.5,measurementUnit:°C
This corresponds to
<timestamp> <data>
The application currently does not have full error handling. It should usually print information on errors to stdout. Some notes:
Exit code 2: writing outputs to disk failed.
