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

References debug, UwFloodingSec::ipAddr_, is_running, neighbor_addr, unconfirmed_pkts, and waiting_uid.

◆ 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

References avg_snr, debug, getNextPacket(), inst_noise, is_running, last_noise, neighbor_addr, unconfirmed_pkts, and waiting_uid.

Here is the call graph for this function:

◆ expire()

void NeighborReputationHandler::expire ( Event * e )

protectedvirtual

Method called when the timer expire

Parameters

Event* pointer to an object of type Event

Here is the call graph for this function:

◆ 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.

◆ removeOldPackets()

void NeighborReputationHandler::removeOldPackets ( )

protected

Removes packet with an old expire time.

◆ 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

References alpha, avg_snr, debug, inst_noise, is_first_pkt, last_noise, and neighbor_addr.

◆ updateInstantNoise()

void NeighborReputationHandler::updateInstantNoise ( double inst_noise_val )

Update the value of the instantaneous noise

Parameters

inst_noise_val value of the instantaneous noise

References debug, inst_noise, UwFloodingSec::ipAddr_, last_noise, and neighbor_addr.
