Wibed User Tutorial


The users can access the Wibed testbed through the wibed server The wibed server provides a set of services that enable the execution and debugging of experiments. In its current state the wibed server supports the following features:

The Experiments page shows information about the running and executed experiments. Through it, information about each separate experiment can be accessed. This page is the starting point of deploying a new experiment.

The Nodes page shows information about the testbed nodes. Through it, information about each separate node can be accessed.

The Admin page allows the execution of commands in any of the nodes that are connected and do not participate in any experiment. It can be used in order to perform administrative operations wihtout having to connect to the node.

The Firmwares page provides information about the firmwares installed on the nodes and is the starting point of doing a firmware upgrade.

The following section describes a generic experiment run, in order to get familiar with the environment. For a more specific example you can take a look here.

Running An Experiment
