错误：

子模块无线电：没有名为'Ieee80211ScalarRadioMedium'的模块类型发现实现模块接口 inet.physicallayer.contract.packetlevel.IRadio（不在加载的NED中文件？），at /Users/ashish/omnetpp-5.3/samples/inet/src/inet/linklayer/ieee80211/Ieee80211Nic.ned:77 - 在网络设置期间的模块（omnetpp :: cModule）clientserverWLAN.host1.wlan [0]（id = 42）

请帮助建立无线主机与AP和服务器之间的通信

尝试运行UDP应用

Answer 1

您应该通过替换

来指定无线电频道的类型

radioMedium: <mediumType> like IRadioMedium

带

radioMedium: Ieee80211ScalarRadioMedium

在Omnet ++中通过AP将无线主机连接到标准主机
