OMNET ++:如何获得无线信号功率? [英] OMNET++: How to obtain wireless signal power?
问题描述
我正在使用新发布的OMNET ++ INET 4.0框架,我想在无线主机(类型为AdhocHost)中获得接收到的信号强度值.我该怎么办?
I am using the newly released INET 4.0 framework for OMNET++ and I would like to obtain the received signal strength value in a wireless host (of type AdhocHost). How may I do that?
推荐答案
在INET
4.0.0中,模块接收到的数据包包含多个 SignalTag.msg :
In INET
4.0.0 the packet received by a module contains several tags. Between others there is SignalPowerInd
tag. According to SignalTag.msg:
此指示指定在接收数据包期间检测到的平均模拟信号功率. 它可能存在于从物理层到应用程序的数据包中.
This indication specifies the average analog signal power that was detected during receiving the packet. It may be present on a packet from the phyiscal layer to the application.
此标记存在于无线MAC层的数据包处理中,例如:
This tag is present in packet processing by a wireless MAC layer, for example:
应用层收到的数据包也包含SignalPowerInd
:
And packet received by application layer contains SignalPowerInd
too:
可以使用标准API从任何层的接收到的无线电数据包中获取
SignalPowerInd
的值.例如,要在UdpBasicApp
中获得它,应在UdpBasicApp.cc
中添加:
One can obtain the value of
SignalPowerInd
from received radio packet in any layer using standard API. For example, to obtain it in UdpBasicApp
one should add in UdpBasicApp.cc
:
#include "inet/physicallayer/common/packetlevel/SignalTag_m.h"
// ...
void UdpBasicApp::socketDataArrived(UdpSocket *socket, Packet *packet) {
if (packet->findTag<SignalPowerInd>() != nullptr) {
auto signalPowerInd = packet->getTag<SignalPowerInd>();
auto rxPower = signalPowerInd->getPower().get();
EV_INFO << "RX power= " << rxPower << "W" << endl;
}
// process incoming packet
processPacket(packet);
}
