Constructor Detail

AckWaiter

public AckWaiter(int sequenceNumber,
                 int nextHop,
                 NormalPacketHeader normalHeader,
                 Packet dataPacket,
                 RouteCache routeCache,
                 ChampAlgorithm champ,
                 Node myNode)

Creates a new instance of AckWaiter

Method Detail

perform

public void perform(Simulation sim,
                    double time)

This event will check to see if an Ack has come in from next hop node. If it has not then it will perform Champ route maintenance operations.

Specified by:

perform in interface SimulationEvent

Parameters:

sim - non-null Simulation

time - simulation time, exactly equal to the result of Simulation.getTime()

isAcknowledged

public boolean isAcknowledged(int nextHop,
                              int sequenceNumber)
