Introduction Wextool is a toolkit that allows to manage a wireless experimentation using a single interface. Wextool v1.0 provides the following functions: Experimentation description Data capture Data filtering Data storing in DB Data post filtering & analyzing Graphical generation
Architecture of Wextool IHM DB manager Storing Pre-processingControl FilteringDisplay Description Execution
Installation First, make sure that: Clients/server stations have the following libs installed: glib2.0 or newer and libxml2.0 or newer. The server station has a php server (Apache or other) and a mysql server
Installation Client side: It is responsible for executing the experimentation scenario on this node It is available as a rpm so, the installation can be done by your software manager. You should install the CREATE_DB (rpm) in your clients in order to allow distributed management of the DB.
Installation Server side It is composed of three part: mysql file, a web site and the application CREATE_DB To install the server: Create a database ´scheduler´ in your DB server Create a database ´joomla´ in your DB server Create a database ´wextool´ in your DB server Use your client mysql to execute the DB files. Deploy the web site in your php server (e.g. in www/wextool, this will correspond to your homepage) After deployment of the web site, you must configure two configuration files: configure.php in the root directory and configure.php in wextool/Create_Schedule
Scenario description To describe the scenario corresponding to your experimentation, you need to define the following parameters using an XML format. Nodes (Stations involved in the experimentation) Acts (software that a node can execute ) Actions (one Act and its environment parameters) Scenario (a group of Actions) Experimentation (a group of nodes and its scenario )
Scenario description: Node Node: 1 # node identifier wlab13 # host name user # user name XXXXX # pwd 22 # port of connection station # station,AP,probe
How to generate XML scenarios? You can write your XML files using your favorite editor, based on xml samples provided. A tool will be available soon to automatically generate XML using a graphical interface. Later on, python script will be another option.
Experimentation phase The experimentation phase corresponds to the execution of your scenario Do not forget to include probes in your scenario. You can use the templates provided along with the sample scripts to configure your hardware and driver
Saving/synchronizing traces simplexml allows to both synchronize and store traces in the database. Storing can be distributed, every probe can run simplexml in the same database Synchronization is automatic because simplexml ensures that the packet exists before possible insertion in the database. Parameters used: File name, e.g. /mnt/radio15/test_07070800.xml DB name, e.g. packet_03 User name, e.g. root User password, e.g. xxx DB server, e.g. localhost AP MAC address, e.g. 0620a64effed
Saving/synchronizing traces Saving & synchronizing trace can be an action in your experimentation: 4 simplexml /mnt/radio15/test_07070800.xml packet_03 root xxx localhost 0620a64effed
Manage Data Traces Data traces can be easily handled using two different tools: Phpmyadmin: the usual mysql admin Fabrik : a plugin that allows you to specify how you want to represent your data
