使用RandomWPMobility、omnet++仿真环境时报错

Question

我正在学习使用 AODV 协议（作为 INET 库的一部分实现）在 omnet++（版本 5.1.1，ubuntu 16.04，x64）中模拟无线通信的教程。我使用了以下代码：

*.host*.mobilityType = "RandomWPMobility"
*.host*.mobility.waitTime= uniform (100s,500s)
*.host*.mobility.speed = uniform(1mps, 10mps)
*.host*.mobility.updateInterval = 0.1s

当运行代码出现错误时：

Cannot schedule message (omnetpp::cMessage)move to the past, t=-9.22337e+06 -- in module (inet::RandomWPMobility) Basic.hostA.mobility (id=39), during network initialization

有人可以帮我解决这个错误吗？

Answer 1

我在本教程中遇到了同样的错误。我不知道它的确切来源，但这是我找到的解决方案：

omnetpp.ini

[Config TestRandomWPMobility2]
network = MobileNetwork

*.host[0].udpApp[0].typename = "UDPBasicApp" # Protocole de communication
*.host[1].udpApp[0].typename = "UDPSink"    # hostMobB = jette les messages recus
*.host*.wlan[0].typename = "IdealWirelessNic"

**.constraintAreaMinX = 0m
**.constraintAreaMinY = 0m
**.constraintAreaMinZ = 0m
**.constraintAreaMaxX = 600m
**.constraintAreaMaxY = 400m
**.constraintAreaMaxZ = 0m
**.updateInterval = 0.1s # test with 0s too, and let getCurrentPosition update the display string from a test module

*.numHosts = 5
**.host*.mobilityType = "RandomWPMobility"
**.host[0].mobility.speed = 10*uniform(20mps,50mps)
**.host*.mobility.speed = uniform(20mps,50mps)
**.host*.mobility.waitTime = uniform(3s,8s)

MobileNetwork.ned:

network MobileNetwork
{
    parameters:
        int numHosts;
        @display("bgb=600,400");
    submodules:
        host[numHosts]: MobileHost {
            parameters:
                @display("p=400+50*numHosts,300+50*numHosts;r=,,#707070");
        }
}

希望对您有所帮助。
