bool ns3::aodv::RoutingTable::DeleteRoute ( Ipv4Address dst )

Delete routing table entry with destination address dst, if it exists.

Parameters

dst	destination address

Returns: true on success

void ns3::aodv::RoutingTable::InvalidateRoutesWithDst ( std::map< Ipv4Address, uint32_t > const & unreachable )

Update routing entries with this destinations as follows:

The destination sequence number of this routing entry, if it exists and is valid, is incremented.
The entry is invalidated by marking the route entry as invalid
The Lifetime field is updated to current time plus DELETE_PERIOD.

bool ns3::aodv::RoutingTable::LookupRoute	(	Ipv4Address	dst,
		RoutingTableEntry &	rt
	)

Lookup routing table entry with destination address dst

Parameters

dst	destination address
rt	entry with destination address dst, if exists

Returns: true on success

bool ns3::aodv::RoutingTable::MarkLinkAsUnidirectional	(	Ipv4Address	neighbor,
		Time	blacklistTimeout
	)

Mark entry as unidirectional (e.g. add this neighbor to "blacklist" for blacklistTimeout period)

Parameters

neighbor	- neighbor address link to which assumed to be unidirectional
blacklistTimeout	- time for which the neighboring node is put into the blacklist

Returns: true on success
