ScenarioManager

simple module

ScenarioManager is for setting up and controlling simulation experiments. You can schedule certain events to take place at specified times, like changing a parameter value, changing the bit error rate of a connection, removing or adding connections, removing or adding routes in a routing table, etc, so that you can observe the transient behaviour.

ScenarioManager executes a script specified in XML. It has a few built-in commands, while other commands are dispatched to be carried out by given simple modules. (The C++ class of these simple modules' needs to implement the IScriptable interface, and the processCommand() method must be redefined accordingly).

An example script:

<scenario>
    <set-param t="10" module="host[1].mobility" par="speed" value="5"/>
    <set-param t="20" module="host[1].mobility" par="speed" value="30"/>
    <at t="50">
        <set-param module="host[2].mobility" par="speed" value="10"/>
        <set-param module="host[3].mobility" par="speed" value="10"/>
        <connect src-module="host[2]" src-gate="ppp[0]"
                 dest-module="host[1]" dest-gate="ppp[0]"
                 channel-type="ned.DatarateChannel">
            <param name="datarate" value="10Mbps" />
            <param name="delay" value="0.1us" />
        </connect>
    </at>
    <at t="60">
        <disconnect src-module="host[2]" src-gate="ppp[0]" />
        <disconnect src-module="host[1]" src-gate="ppp[0]" />
    </at>
</scenario>

Built-in commands: <set-param>, <set-channel-attr>, <at>.

All commands have a t attribute which carries the simulation time at which the command has to be carried out. You can group several commands to be carried out at the same simulation time using <at>, and then only the <at> command is needed to have a t attribute.
