OMNeT++ CODE WSN
Wireless Sensor Network Projects Source Code using OMNeT++
OMNET++ CODE WSN referred as Wireless Sensor Network is a network of RF transceivers, sensors, machine controllers, microcontrollers, and user interface devices with at least two nodes communicating by means of wireless transmissions.
- Completed OMNeT++ WSN Code 53%
- On-Going OMNeT++ WSN CODE 27%
Application of WSN:
- Bring out fertilizer/pesticides/irrigation only when needed.
- Intrusion detection into industrial sites and other restricted areas.
- Tire pressure monitoring.
- Control of leakage in chemical plants.
- Long-term surveillance of chronically ill patients.
- Post-operative or intensive care.
Characteristics of WSN:
- Heterogeneity of nodes.
- Ability to cope with node failures.
- Mobility of nodes.
- Ease of use.
- Scalability to large scale of deployment.
- Power consumption constraints for nodes using batteries.
- Ability to withstand harsh environmental conditions.
Sample code for WSN:
void Radio::setBitrate(double bitrate)
{
if (rs.getBitrate() == bitrate)
return;
if (bitrate < 0)
error(“setBitrate(): bitrate cannot be negative (%g)”, bitrate);
if (rs.getState() == RadioState::TRANSMIT)
error(“changing the bitrate while transmitting is not allowed”);
EV << “Setting bitrate to ” << (bitrate/1e6) << “Mbps\n”; emit(bitrateSignal, bitrate); rs.setBitrate(bitrate); } void Radio::setRadioState(RadioState::State newState) { if (rs.getState() != newState) { emit(radioStateSignal, newState); if (newState == RadioState::SLEEP || newState == RadioState::OFF) { disconnectTransceiver(); disconnectReceiver(); } else if (rs.getState() == RadioState::SLEEP || rs.getState() == RadioState::OFF) { connectTransceiver(); connectReceiver(); // the connection change the state } rs.setState(newState); nb->fireChangeNotification(NF_RADIOSTATE_CHANGED, &rs);
}
}
{
if (rs.getBitrate() == bitrate)
return;
if (bitrate < 0)
error(“setBitrate(): bitrate cannot be negative (%g)”, bitrate);
if (rs.getState() == RadioState::TRANSMIT)
error(“changing the bitrate while transmitting is not allowed”);
EV << “Setting bitrate to ” << (bitrate/1e6) << “Mbps\n”; emit(bitrateSignal, bitrate); rs.setBitrate(bitrate); } void Radio::setRadioState(RadioState::State newState) { if (rs.getState() != newState) { emit(radioStateSignal, newState); if (newState == RadioState::SLEEP || newState == RadioState::OFF) { disconnectTransceiver(); disconnectReceiver(); } else if (rs.getState() == RadioState::SLEEP || rs.getState() == RadioState::OFF) { connectTransceiver(); connectReceiver(); // the connection change the state } rs.setState(newState); nb->fireChangeNotification(NF_RADIOSTATE_CHANGED, &rs);
}
}
