A helper to make it easier to create a grid topology with p2p links.


Constructor & Destructor Documentation

ns3::PointToPointGridHelper::PointToPointGridHelper ( uint32_t  nRows,
uint32_t  nCols,
PointToPointHelper  pointToPoint 
)

Create a PointToPointGridHelper in order to easily create grid topologies using p2p links

Parameters:
nRowstotal number of rows in the grid
nColstotal number of colums in the grid
pointToPointthe PointToPointHelper which is used to connect all of the nodes together in the grid

Member Function Documentation

void ns3::PointToPointGridHelper::AssignIpv4Addresses ( Ipv4AddressHelper  rowIp,
Ipv4AddressHelper  colIp 
)

Assigns Ipv4 addresses to all the row and column interfaces

Parameters:
rowIpthe Ipv4AddressHelper used to assign Ipv4 addresses to all of the row interfaces in the grid
colIpthe Ipv4AddressHelper used to assign Ipv4 addresses to all of the row interfaces in the grid
void ns3::PointToPointGridHelper::BoundingBox ( double  ulx,
double  uly,
double  lrx,
double  lry 
)

Sets up the node canvas locations for every node in the grid. This is needed for use with the animation interface

Parameters:
ulxupper left x value
ulyupper left y value
lrxlower right x value
lrylower right y value
Ipv4Address ns3::PointToPointGridHelper::GetIpv4Address ( uint32_t  row,
uint32_t  col 
)

This returns an Ipv4 address at the node specified by the (row, col) address. Technically, a node will have multiple interfaces in the grid; therefore, it also has multiple Ipv4 addresses. This method only returns one of the addresses. If you picture the grid, the address returned is the left row device of all the nodes, except the left-most grid nodes, which returns the right row device.

Parameters:
rowthe row address of the node desired
colthe column address of the node desired
Returns:
Ipv4Address of one of the interfaces of the node specified by the (row, col) address
Ptr<Node> ns3::PointToPointGridHelper::GetNode ( uint32_t  row,
uint32_t  col 
)
Parameters:
rowthe row address of the node desired
colthe column address of the node desired
Returns:
a pointer to the node specified by the (row, col) address
void ns3::PointToPointGridHelper::InstallStack ( InternetStackHelper  stack)
Parameters:
stackan InternetStackHelper which is used to install on every node in the grid
