BroadcastLinkQuality (const wns::pyconfig::View &config_, BeaconLinkQualityMeasurement *parent_, wns::service::dll::UnicastAddress peerAddress_, wns::service::dll::UnicastAddress myAddress_, wns::simulator::Time interval_)

Creator.

void deadPeerMeasurement ()

Indicates the reception of a beacon from peer without a measurement.

wns::Ratio getAverageSINR ()

Returns the average sinr out of the sinr MIB.

double getSuccessRate ()

Returns the received beacon success rate.

bool isActive () const

Returns if beacons have been received at all.

void newBeacon (wns::simulator::Time interval)

Indicates the reception of a new beacon from peer.

Metric newPeerMeasurement (double peerSuccessRate, wns::Ratio peerSINR)

Indicates a new measurement of the Me->Peer link.

Private Member Functions

double getBestRate (wns::Ratio sinr)

Converts SINR to Mbps.

void onTimeout ()

Is called if no beacon was received after 1.5 beacon intervalls.

Private Attributes

const wns::pyconfig::View config

Store the config.

wns::simulator::Time curInterval

The last indicated beacon interval.

bool linkCreated

Remember if the link is created in the routing table, it has to be constantly active to remain created.

const wns::simulator::Time maximumACKDuration

expected duration of an ACK for metric calculation

const int maxMissedBeacons

Maximum number of missed beacons befor a link is closed.

const Bit meanFrameSize

frame size for metric calculation

int missedBeaconsInRow

Counts how many beacons are missed in a row, determines if the link is active.

wns::service::dll::UnicastAddress myAddress

My address.

BeaconLinkQualityMeasurement * parent

Callback-pointer to the parent.

const
wns::service::dll::UnicastAddress peerAddress

remote address

const wns::simulator::Time preambleDuration

Preamble duration for metric calculation.

IPathSelection * ps

Pointer to the path selection entity.

const double scalingFactor

scaling factor for metric calculation

const wns::simulator::Time sifsDuration

SIFS duration for metric calculation.

wifimac::management::SINRInformationBase * sinrMIB

Pointer to the node's SINR informatin base.

const wns::simulator::Time slotDuration

Slot duration for metric calculation.

wns::SlidingWindow successRate

Storage of the success rate peer --> me.
