我正在使用INET带有OMNET++. 我已经定制了我的Ieee80211ScalarRadio模块，以读取从我的AdhocHost.
这是我的自定义CIeee80211ScalarRadio.ned文件：

import inet.physicallayer.ieee80211.packetlevel.Ieee80211ScalarRadio;

module CIeee80211ScalarRadio extends Ieee80211ScalarRadio
{
    @class(inet::physicallayer::CIeee80211ScalarRadio);
}

这是相应的CIeee80211ScalarRadio.cc文件：

#include "inet/physicallayer/ieee80211/packetlevel/Ieee80211Radio.h"
#include "inet/physicallayer/common/packetlevel/SignalTag_m.h"
#include "inet/linklayer/common/MacAddressTag_m.h"


#include <omnetpp.h>
#include <string>

#include <cmath>
#include <iostream>

namespace inet{
namespace physicallayer{
class CIeee80211ScalarRadio : public Ieee80211Radio{
protected:
   virtual void sendUp(Packet *macFrame) override;
};

Define_Module(CIeee80211ScalarRadio);

void CIeee80211ScalarRadio::sendUp(Packet *macFrame)
{
    if (macFrame->findTag<SignalPowerInd>() != nullptr) {
           auto signalPowerInd = macFrame->getTag<SignalPowerInd>();
           auto rxPower = signalPowerInd->getPower().get();
           double pdBm = 10*log10(rxPower)+30;
           EV_INFO << "RX power = " << pdBm << " dBm" << endl;
    }
    if(macFrame->findTag<MacAddress>() != nullptr){
        auto macAddress = macFrame->getTag<MacAddress>();
        EV_INFO << "Mac Address = " << macAddress << endl;
    }

    Radio::sendUp(macFrame);
}
}//namespace physicallayer
}//namespace inet

如您所见，我正在重写Ieee80211ScalarRadio'ssendUp()方法以从macFrame.
我可以成功提取RxPower，但是，当我为 做同样的事情时，我在自己的源代码MacAddress中得到以下编译器错误：INET

../inet4/src/inet/common/packet/tag/TagSet.h:123:36: error: static_cast from 'std::__1::__vector_base<omnetpp::cObject *, std::__1::allocator<omnetpp::cObject *> >::value_type' (aka 'omnetpp::cObject *') to 'inet::MacAddress *', which are not related by inheritance, is not allowed

我怎样才能在MacAddress没有任何错误的情况下获得价值？

包含 MAC 地址的标签的正确名称是MacAddressInd，不是MacAddress。它已声明MacAddressTag_m.h您已包含在其中。

附加说明：MacAddressInd包含两个地址：源和目标。所以你应该明确你想要获得哪一个，例如：

auto macAddress = macFrame->getTag<MacAddressInd>()->getSrcAddress();
