Detailed Description
Recieve Properties Control Message is sent from the emulator physical layer with every upstream packet. It contains the tx time stamp, propagation delay, span and reciever sensitivity associated with the packet and the reciever.
- Note
- The Start of Transmission (SoT) is the tx time + propagation delay + offset of the first frequency segment.
- Instances are immutable

Member Function Documentation
◆ clone()
|
overridevirtual |
Clones the control message on the heap
- Returns
- cloned message
- Note
- Caller assumes ownership of the clone
Implements EMANE::Cloneable< ControlMessage >.
Definition at line 122 of file receivepropertiescontrolmessage.cc.
◆ create()
|
static |
Creates a ReceivePropertiesControlMessage on the heap
- Parameters
-
txTime Time value used as the tx time in the common PHY Header propagation Propagation delay in microseconds span Length of time in microseconds between the earliest start-of-reception (SoR) frequency segment and latest end-of-reception (EoR) segment. dReceiverSensitivitydBm Receiver sensitivity in dBm
- Note
- Once a control message is passed to another NEM layer using EMANE::UpstreamTransport::processUpstreamPacket(), EMANE::UpstreamTransport::processUpstreamControl(), EMANE::DownstreamTransport::processDownstreamPacket() or EMANE::DownstreamTransport::processDownstreamControl() object ownership is transferred to the emulator infrastructure along with deallocation responsibility. It is not valid to use a control message instance after it has been passed to another layer.

◆ getId()

Gets the control message id
- Returns
- control messase id
Definition at line 64 of file controlmessage.h.
◆ getPropagationDelay()
| EMANE::Microseconds EMANE::Controls::ReceivePropertiesControlMessage::getPropagationDelay | ( | ) | const |
Gets the propagation delay in microseconds
- Returns
- propagation delay in microseconds
Definition at line 111 of file receivepropertiescontrolmessage.cc.
◆ getReceiverSensitivitydBm()
| double EMANE::Controls::ReceivePropertiesControlMessage::getReceiverSensitivitydBm | ( | ) | const |
Gets the receiver sensitivity in dBm
- Returns
- receiver sensitivity id dBm
Definition at line 105 of file receivepropertiescontrolmessage.cc.
◆ getSpan()
| EMANE::Microseconds EMANE::Controls::ReceivePropertiesControlMessage::getSpan | ( | ) | const |
Gets the message span
- Returns
- message span in microseconds
- Note
- The message span is the length of time between the earliest start-of-reception (SoR) frequency segment and latest end-of-reception (EoR) segment. The purpose of the span is to provide a simple mechanism to query the spectrum service for the noise window that is guaranteed to cover the total duration of all the segments combined. The span will "span" any gaps between segments allowing for creating a logical two dimensional matrix of noise, frequencies vs time, for quick access to the noise information occurring during the entire message duration.
- The main consideration is that one large noise window request is less expensive than many small requests.
- The span is the length of time after transmit time, propagation delay and segment offset have been accounted for.
- Since the first frequency segment always contains the earliest offset, a query to the Spectrum Service should use a calcualted SoR time and the span as the query duration:

◆ serialize()

Gets the serialized form of the object
- Returns
- serialization
- Exceptions
-
SerializationException
- Note
- Most objects use Google Protocol Buffers to perform serialization. This is why the Serialization type is a std::string. The serialized data is binary, non-printable data. The std::string just provides a simple API.
