Question

我在主机连接到一个AccessPoint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。我想做的就是发送一些间隔的信标帧，并在主机之间发送UDP数据报。

.ned file：

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");
    }
}

Omnetpp.ini文件：

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

[Config Ping2] # __interactive__
description = "n hosts"

我发现当我改变行

wlan[*].mgmtType = "Ieee80211MgmtAP";

在.ned文件中，数据报从一个主机到另一个主机，但随后信标的发送不起作用。

另外，当udp数据报待处理时，我在模拟期间从命令窗口获得一些信息：

**事件＃320 T = 0.02 Lan80211.host [0] .udpApp [1]（UDPBasicApp，id = 15），关于selfmsg sendTimer' (cMessage, id=10) ** Event #321 T=0.02 Lan80211.host[1].udpApp[1] (UDPBasicApp, id=35), on selfmsg sendTimer'（cMessage，id = 21） **事件＃322 T = 0.02 Lan80211.host [0] .udp（UDP，id = 16），在UDPBasicAppData-2' (cPacket, id=304) Sending app packet UDPBasicAppData-2 over IPv4. ** Event #323 T=0.02 Lan80211.host[1].udp (UDP, id=36), on UDPBasicAppData-2'上（cPacket，id = 305）通过IPv4发送应用程序包UDPBasicAppData-2。 **事件＃324 T = 0.02 Lan80211.host [0] .networkLayer.ip（IPv4，id = 18），UDPBasicAppData-2' (UDPPacket, id=306) Sending datagram UDPBasicAppData-2'，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), on UDPBasicAppData-2'（UDPPacket，id = 307）使用dest = 145.236.0.1发送数据报UDPBasicAppData-2' with dest=145.236.0.1 Routing datagram UDPBasicAppData-2'：输出接口是wlan0，下一跳地址：没有下一跳地址，使用目标地址145.236.0.1（代理ARP）发送数据包到接口wlan0

有任何建议吗？

谢谢， MB
