Member Function Documentation

uint32_t ns3::dsr::RreqTable::CheckUniqueRreqId ( Ipv4Address dst )

The following code generates new request id for each destination

Definition at line 157 of file dsr-rreq-table.cc.

References NS_LOG_DEBUG, NS_LOG_INFO, and NS_LOG_LOGIC.

bool ns3::dsr::RreqTable::FindSourceEntry	(	Ipv4Address	src,
		Ipv4Address	dst,
		uint16_t	id
	)

Find the source request entry in the route request queue, return false if not found

Parameters

src	the source address we just received the source request
dst	the destination address the request is targeted at
id	the identification number for this request

Clear the received source request entry

Check if we have found one duplication entry or not

if this entry is not found, we need to save the entry in the cache, and then return false for the check

Definition at line 254 of file dsr-rreq-table.cc.

References NS_LOG_FUNCTION, and NS_LOG_LOGIC.

BlackList * ns3::dsr::RreqTable::FindUnidirectional ( Ipv4Address neighbor )

Verify if entry is unidirectional or not(e.g. add this neighbor to "blacklist" for blacklistTimeout period)

Parameters

neighbor - neighbor address link to which assumed to be unidirectional

Returns: true on success

Definition at line 210 of file dsr-rreq-table.cc.

TypeId ns3::dsr::RreqTable::GetTypeId ( void )

static

Get the type identificator.

Returns: type identificator

Definition at line 44 of file dsr-rreq-table.cc.

References ns3::TypeId::SetParent().

void ns3::dsr::RreqTable::Invalidate ( )

set the unidirectional entry as QUESTIONABLE state

Definition at line 200 of file dsr-rreq-table.cc.

bool ns3::dsr::RreqTable::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 successRemove all expired black list entries

Definition at line 225 of file dsr-rreq-table.cc.
