Class MACActorBase

    • Field Detail

      • aSifsTime

        public Parameter aSifsTime
        The parameter for SIFS (Short Inter Frame Space). This time is used to separate transmissions belong to a single dialog. This Value is fixed per PHY and is calculated base on the time that takes for the transmitting part to switch back to receive mode.

      • aPreambleLength

        public Parameter aPreambleLength
        The size of the Preamble header in a frame. The Preamble header contains synchronization information and timing information for the frame.

      • aPlcpHeaderLength

        public Parameter aPlcpHeaderLength
        The size of the PLCP header in a frame. The PLCP header contains logical information for the physical layer to decode the frame.

      • aSlotTime

        public Parameter aSlotTime
        The time unit for the backoff time

      • aRxRfDelay

        public Parameter aRxRfDelay
        The nominal time between the end of a symbol at the air interface to the issuance of a PMD-DATA.indicate to the PLCP.

      • aRxPlcpDelay

        public Parameter aRxPlcpDelay
        The nominal time that the PLCP uses to deliver a bit from the PMD receive path to the MAC.

      • aCWmin

        public Parameter aCWmin
        The minimum size of the contention window, in units of aSlotTime.

      • aCWmax

        public Parameter aCWmax
        The maximum size of the contention window, in units of aSlotTime.

      • dot11ShortRetryLimit

        public Parameter dot11ShortRetryLimit
        The maximum number of retransmissions for MPDUs

      • dot11LongRetryLimit

        public Parameter dot11LongRetryLimit
        The maximum number of retransmissions for RTS

      • dotllRTSThreshold

        public Parameter dotllRTSThreshold
        The threshold for the length of a MPDU, below which a RTS is not necessary.

    • Constructor Detail

      • MACActorBase

        public MACActorBase​(CompositeEntity container,
                    java.lang.String name)
             throws IllegalActionException,
                    NameDuplicationException
        Construct an actor with the specified name and container. The container argument must not be null, or a NullPointerException will be thrown. If the name argument is null, then the name is set to the empty string. This constructor write-synchronizes on the workspace.
        Parameters:
        container - The container.
        name - The name of the actor.
        Throws:
        IllegalActionException - If the container is incompatible with this actor.
        NameDuplicationException - If the name coincides with an actor already in the container.

      • attributeChanged

        public void attributeChanged​(Attribute attribute)
                      throws IllegalActionException
        If the specified attribute is changed, check that a positive number is given. Otherwise, defer to the base class.
        Overrides:
        attributeChanged in class NamedObj
        Parameters:
        attribute - The attribute that changed.
        Throws:
        IllegalActionException - If the change is not acceptable to this container.

      • getID

        protected int getID()
        Check whether this has a id attribute. If yes, return the value of it; if no, return the default value -2.
        Returns:
        return the value of the id attribute of -2 if no such an attribute.
