I need to implement TDMA and FDMA based slot assignment protocol. I have written the code for TDMA slot assignment but confused about the FDMA part. Will someone please guide me in writing the code for FDMA for a simple scenario. In which two nodes are using full duplex radio and working on two different frequencies. If node1 needs to communicate to node 2 then node 2 must shift its frequency to node 1 frequency. I have not worked with the radios yet. In TDMA part i am using senddirect for sending messages. There is mulitradio exmaple in inet but it uses two or more than two radios for single module. I want to use one full duplex radio for single module. How should i begin working with the FDMA part?
Yes i know the concept but i am having trouble in implementing a basic example in omnet++ as i have explained in above question. The following code will change the channel but there is no option for changing transmission frequency or reception reception frequency.
int actualChannel = -1;struct channelsInfo {
double bandwith;
double mean;
};
std::vector channels = {{2e6,2.405e9},{2e6,2.410e9},{2e6,2.415e9},{2e6,2.420e9},{2e6,2.425e9},
{2e6,2.430e9},{2e6,2.435e9},{2e6,2.440e9},{2e6,2.445e9},{2e6,2.450e9},
{2e6,2.455e9},{2e6,2.460e9},{2e6,2.465e9},{2e6,2.470e9},{2e6,2.475e9},{2e6,2.480e9}};
void MyMAC::setChannel(const int &channel) {if (channel < 11 || channel > 26)
return;
if (actualChannel == channel)
return;
EV setControlInfo(configureCommand);
sendDown(message);
}
have you done the tdma tree topology or centralized network in omnet?
please need some help Sana Saleem
