Ieee802154NarrowbandInterface

compound module

This module implements an IEEE 802.15.4 narrowband network interface.

pcapRecorder[numPcapRecorders] : PcapRecorder

Records PCAP traces of frames sent/received by other modules within the same host.

Source:
pcapRecorder[numPcapRecorders]: PcapRecorder {
    parameters:
        moduleNamePatterns = ".^";
        @display("p=100,100;is=s");
} clock : like IClock

IClock: This module interface is implemented by clock models.

Source:
clock: <default("")> like IClock if typename != "" {
    parameters:
        @display("p=100,200;is=s");
} queue : like IPacketQueue

DropTailQueue: This module is a limited packet queue which drops packets at the tail of the queue.

IPacketQueue: This module interface is implemented by packet queue modules.

Source:
queue: <default("DropTailQueue")> like IPacketQueue {
    parameters:
        packetCapacity = default(100);
        @display("p=200,100;q=l2queue");
} mac : Ieee802154NarrowbandMac

Source:
mac: Ieee802154NarrowbandMac {
    parameters:
        @display("p=300,100");
} radio : like IRadio

IRadio: Module interface for radio modules.

Source:
radio: <default("Ieee802154NarrowbandScalarRadio")> like IRadio {
    parameters:
        @display("p=300,200");
}
