我正在尝试在Castalia中模拟一个传感器阵列，该传感器阵列每个节点可以使用多个传感器，但是当我运行模拟时，它将传感器名称作为一项，最后显示传感器索引和传感器值首先提到。请帮忙！！如何获取每个节点检测多个传感器的信息 omnetpp.ini（值报告）

我注意到的一些事情
PhysicalProcess模块中没有printDebugInfo参数。可能您追捕的是collectTraceInfo。
如果您只想更新某些参数所取的值，那么编辑ned文件不是一个好主意。这就是ini文件的用途。因此，无需更改ned文件中的默认值，只需在ini文件中分配这些值即可。例如，您已经在ini文件中分配了以下参数：
SN.node[*].SensorManager.sensorTypes = "Temperature Bloodglucose"
SN.node[*].SensorManager.corrPhyProcess = "0 1"
您也不需要在ned文件中设置它们。还要注意，在ned文件中，您将第二个字符串设置为“ 0,1”而不是“ 0 1”。 ini文件将覆盖ned文件的值，因此您将得到“ 0 1”。幸运的是，空格分隔的值是正确的语法。
然后，您开始定义新的.ned .cc和.h文件。为什么？这些没有任何作用。您尚未在ini文件中设置变量SN.physicalProcessName。这意味着它将采用默认值CustomizablePhysicalProcess。您似乎将物理过程模块视为CustomizablePhysicalProcess，因为我看到您定义了它们的参数inputType和directNodeValueAssignment，它们仅在CustomizablePhysicalProcess模块中存在。因此，我不理解尝试完全定义新的物理过程模块会得到什么。
由于您有2个物理过程，这意味着每个节点中的SensorManager需要连接到这2个物理过程（定义您的物理过程的2个模块）。为此，只需将SensorManager的所有参数设置为2个项的数组即可（定义为一个数组（格式为以空格分隔的字符串））。
您可以在SensorManager.ned中找到所有相关参数（但不要编辑ned文件，只需在ini文件中进行设置即可）。以下是仅供参考的参数（请注意，您已经在ini文件中设置了sensorTypes和corrPhyProcess ，您只需还要设置其余的）：
string pwrConsumptionPerDevice = default ("0.02");
string sensorTypes = default ("Temperature"); // Humidity OR Temperature OR Light
string corrPhyProcess = default ("0"); //holds the indexes of the corresponding phy processes for
//each sensor (usually it should be : "0 1 2 3")
string maxSampleRates = default ("1"); //number of samples per second for each sensor
string devicesBias = default ("0.1"); //If the output signal is not zero when the measured property is zero
string devicesDrift = default (""); //If the output signal slowly changes independent of the
//measured property
string devicesNoise = default ("0.1"); //random deviation of the signal that varies in time
string devicesHysterisis = default (""); //the sensor not instantly follows the change of the property
//being measured and therefore involves the history of the
//measured property
string devicesSensitivity = default ("0"); //holds the minimum value which can be sensed by each sensing device.
string devicesResolution = default ("0.001"); //holds the sensing resolution for each device
我不确定多个phyProcesses和多种感应方式是否存在其他问题，因为此功能尚未在2.0之后的版本中进行过测试，因此可能根本无法使用（但希望它做了一些小的调整才能使其正常工作）。
