Member Function Documentation

addUnconfirmedPkt()

bool NeighborReputationHandler::addUnconfirmedPkt	(	int	uid,
		double	expire_time
	)

Add in the map the unconfirmed packets with the corresponidg timeout.

Parameters

uid	unique id of the analyzed packet
expire_time	expire time for the forwarding of neighbor

Returns

true if the packet is correctly inserted, false oterwhise

Definition at line 104 of file uwflooding-sec.cpp.

checkUnconfirmedPkt()

bool NeighborReputationHandler::checkUnconfirmedPkt

(

int

uid

)

Check if the packet with the given uid is an unconfirmed one and set it as confirmed.

Parameters

uid	unique id if the analyzed packet

Returns

true if the packet is present, false otherwise

Definition at line 136 of file uwflooding-sec.cpp.

expire()

void NeighborReputationHandler::expire ( Event *  e )

protectedvirtual

Method called when the timer expire.

Parameters

Event*

pointer to an object of type Event

Definition at line 177 of file uwflooding-sec.cpp.

getNextPacket()

bool NeighborReputationHandler::getNextPacket ( int &  uid, double &  exp_time  ) const

protected

Returns as reference the uid of the next packet that id going to expire.

Returns false if there are no packets in the map.

Parameters

uid	unique id of the next packet that is going to expire.
exp_time	expire time of the next packet that is going to expire.

Returns

false if there is no packets in the map, true otherwise.

Definition at line 217 of file uwflooding-sec.cpp.

removeOldPackets()

updateChannelMetrics()

void NeighborReputationHandler::updateChannelMetrics	(	double	val_snr,
		double	last_noise_val
	)

Update average SNR.

Parameters

val_snr	new SNR value
last_noise_val	value of the noise for the last received packet

Definition at line 262 of file uwflooding-sec.cpp.

updateInstantNoise()

void NeighborReputationHandler::updateInstantNoise

(

double

inst_noise_val

)

Update the value of the instantaneous noise.

Parameters

inst_noise_val

value of the instantaneous noise
