Implementation to actually run this TestCase.

Subclasses should override this method to conduct their tests.

Implements ns3::TestCase.

ReceivedPacketAtEndDevice()

void DownlinkPacketTest::ReceivedPacketAtEndDevice	(	uint8_t	txCount,
		bool	ack,
		Time	firstAttempt,
		Ptr< Packet >	packet )

Trace the outcome of MAC layer's confirmed packet retransmission and acknowledgement.

This trace sink is only used here to determine whether an ack was received by the end device after sending a package requiring an acknowledgement.

Parameters

txCount	Number of transmissions attempted during the process.
ack	Whether the retransmission process led to acknowledgement.
firstAttempt	Timestamp of the initial transmission attempt.
Packet	The packet being retransmitted.

SendPacket()

void DownlinkPacketTest::SendPacket	(	Ptr< Node >	endDevice,
		bool	requestAck )

Send a packet from the input end device.

Parameters

endDevice	A pointer to the end device Node.
requestAck	Whether to require an acknowledgement from the server.
