Problems linking in windows against libINET.dll

[Alfonso Ariza Quintana]

I have a port of OpenFlow for the latest version of inet. In Linux, I can generate the program, but in windows, I have some problems,

Apparently, there are several duplicate objects

If I generate the project with g++ I have this

In the second case, it is possible that the problem could be related to the inline definition

Can anybody help me through it...

Now I am using omnet++.. I am doing modifications to the co-existence as per my requirement. I have taken 3 wifi devices for every 2kms apart which are stable and a moving device (Linear Mobility) which is below 50m to the 1st wifi device. My requirement is to to observe the throughput for these devices for different powers.

Type of application is "UdpBasicApp".

After doing simulation I am getting throughput is different for every device.

My requirement is to get same datarate for all the devices.

*.wifiHost21.numApps = 3

*.wifiHost21.app[*].typename = "UdpBasicApp"

*.wifiHost21.app[0].destAddresses = "wifiHost1"

*.wifiHost21.app[1].destAddresses = "wifiHost2"

*.wifiHost21.app[2].destAddresses = "wifiHost3"

*.wifiHost21.app[*].messageLength = 1000 byte

*.wifiHost21.app[0].packetName = "UDPData-1-"

*.wifiHost21.app[1].packetName = "UDPData-2-"

*.wifiHost21.app[2].packetName = "UDPData-3-"

*.wifiHost21.app[0].startTime = uniform(0.1s,0.1us)

*.wifiHost21.app[1].startTime = uniform(0.2s,0.1us)

*.wifiHost21.app[2].startTime = uniform(0.3s,0.1us)

*.wifiHost21.app[*].sendInterval =0.4 ms

*.wifiHost21.app[*].destPort = 5000

*.wifiHost1.numApps = 1

*.wifiHost1.app[0].typename = "UdpSink"

*.wifiHost1.app[0].localPort = 5000

*.wifiHost2.numApps = 1

*.wifiHost2.app[0].typename = "UdpSink"

*.wifiHost2.app[0].localPort = 5000

*.wifiHost3.numApps = 1

*.wifiHost3.app[0].typename = "UdpSink"

*.wifiHost3.app[0].localPort = 5000

I have attached the throughput file too ... I expected to have same data rate for all 3 devices. And my doubt is in the throughput why all 3 devices having bell shape at 35-45 sec only even they are separated with 2km distance. plz help me through this sir.

I am using Omnetpp-5.6.2 and inet-4.2.5
