我在连接到一个接入点的主机之间发送 udp 数据报时遇到问题。下面我展示了我的 ned 和 omnetpp.ini 文件，我使用了 inet/examples/wireless/lan80211 中的示例。我要做的就是以一定的间隔发送信标帧，并在主机之间发送 UDP 数据报。

.ned 文件：

package inet.examples.wireless.lan80211;

import inet.networklayer.autorouting.ipv4.IPv4NetworkConfigurator;
import inet.nodes.inet.WirelessHost;
import inet.nodes.wireless.AccessPoint;
import inet.world.radio.ChannelControl;


network Lan80211
{
parameters:
    int numHosts;
submodules:
    host[numHosts]: WirelessHost {
        @display("r=,,#707070");

        wlan[*].mgmtType = "Ieee80211MgmtSTASimplified";
    }
    ap: AccessPoint {
        @display("p=213,174;r=,,#707070");

        wlan[*].mgmtType = "Ieee80211MgmtAP";
    }
    channelControl: ChannelControl {
        numChannels = 2;
        @display("p=61,46");
    }
    configurator: IPv4NetworkConfigurator {
        config=xml("<config><interface hosts='*' address='145.236.x.x'       netmask='255.255.0.0'/></config>");
        @display("p=140,50");
    }
}

omn​​etpp.ini 文件：

[Config Ping1]
description = "host1 pinging host0"
*.numHosts = 2

[Config Ping2] # __interactive__

我发现当我换线时

wlan[*].mgmtType = "Ieee80211MgmtAP";

在 .ned 文件中，数据报从一台主机发送到另一台主机，但信标的发送不起作用。

此外，当 udp 数据报未决时，我在模拟期间从命令窗口获取一些信息：

** 事件#320 T=0.02 Lan80211.host[0].udpApp[1] (UDPBasicApp, id=15), on selfmsg sendTimer' (cMessage, id=10) ** Event #321 T=0.02 Lan80211.host[1].udpApp[1] (UDPBasicApp, id=35), on selfmsgsendTimer' (cMessage, id=21) ** 事件#322 T=0.02 Lan80211.host[ 0].udp (UDP, id=16), on UDPBasicAppData-2' (cPacket, id=304) Sending app packet UDPBasicAppData-2 over IPv4. ** Event #323 T=0.02 Lan80211.host[1].udp (UDP, id=36), onUDPBasicAppData-2' (cPacket, id=305) 通过 IPv4 发送应用数据包 UDPBasicAppData-2。** 事件 #324 T=0.02 Lan80211.host[0].networkLayer.ip (IPv4, id=18)，在UDPBasicAppData-2' (UDPPacket, id=306) Sending datagramUDPBasicAppData-2' 上，dest=145.236.0.2 路由数据报UDPBasicAppData-2' with dest=145.236.0.2: output interface is wlan0, next-hop address: <unspec> no next-hop address, using destination address 145.236.0.2 (proxy ARP) Sending out packet to interface wlan0 ** Event #325 T=0.02 Lan80211.host[1].networkLayer.ip (IPv4, id=38), onUDPBasicAppData-2' (UDPPacket, id=307) Sending datagram UDPBasicAppData-2' with dest=145.236.0.1 Routing datagramUDPBasicAppData-2' with dest=145.236.0.1: output interface is wlan0, ​​next-hop address: no next-hop address, using destination address 145.236.0.1 (proxy ARP)

有什么建议吗？

谢谢，MB
