Detailed Description

Helper class used to assign positions and mobility models to nodes for a group mobility configuration.

This helper can be used for group mobility configuration and installation onto a group of nodes, in which there is a reference (parent) mobility model that is the same for all nodes, and similarly configured (but distinct) child mobility models.

Constructor & Destructor Documentation

◆ GroupMobilityHelper()

ns3::GroupMobilityHelper::GroupMobilityHelper ( )

Construct a group mobility helper.

Definition at line 30 of file group-mobility-helper.cc.

◆ ~GroupMobilityHelper()

ns3::GroupMobilityHelper::~GroupMobilityHelper ( )

Destroy a group mobility helper.

Definition at line 35 of file group-mobility-helper.cc.

Member Function Documentation

◆ AssignStreams()

int64_t ns3::GroupMobilityHelper::AssignStreams	(	NodeContainer	c,
		int64_t	stream )

Assign a fixed random variable stream number to the random variables used by the mobility models on these nodes.

Return the number of streams (possibly zero) that have been assigned. The Install() method should have previously been called by the user.

Note: If the PositionAllocator used contains random variables, they will not be affected by this call to AssignStreams because they are used earlier during Install() time. If the user needs to assign a fixed stream number to a PositionAllocator used with this helper, the user should instantiate it outside of the helper, call AssignStreams() on it, and then pass the pointer of it to this helper.

Parameters

c	NodeContainer of the set of nodes containing the MobilityModels that should be modified to use a fixed stream
stream	first stream index to use

Returns: the number of stream indices assigned by this helper
