OMNET++ VANET PROJECTS is defined as a spontaneous ad hoc network formed over vehicles moving or between vehicles and infrastructure with vehicle-to infrastructure (V2I) communication. Such VANETs in which vehicles can communicate with each other and also with roadside infrastructure provide a means to improve road safety by enabling a number of potential applications for driver assistance, collision warning, traffic information, and monitoring using sumo vanet.
Applications of VANET:
Challenges on VANET:
Sample code for VANET:
void ChannelAccess::sendToChannel(cPacket *msg)
{
const NicEntry::GateList& gateList = cc->getGateList( getParentModule()->getId());
NicEntry::GateList::const_iterator i = gateList.begin();
if(useSendDirect){
if( i != gateList.end() ){
simtime_t delay = SIMTIME_ZERO;
for(; i != –gateList.end(); ++i){
delay = calculatePropagationDelay(i->first);
int radioStart = i->second->getId();
int radioEnd = radioStart + i->second->size();
for (int g = radioStart; g != radioEnd; ++g)
sendDirect(static_cast<cPacket*>(msg->dup()),
delay, msg->getDuration(), i->second->getOwnerModule(), g);
}
delay = calculatePropagationDelay(i->first);
int radioStart = i->second->getId();
int radioEnd = radioStart + i->second->size();
for (int g = radioStart; g != –radioEnd; ++g)
sendDirect(static_cast<cPacket*>(msg->dup()),
delay, msg->getDuration(), i->second->getOwnerModule(), g);
sendDirect(msg, delay, msg->getDuration(), i->second->getOwnerModule(), radioEnd);
}
else{
coreEV << “Nic is not connected to any gates!” << endl;
delete msg;
}
}
else{
coreEV <<“sendToChannel: sending to gates\n”; if( i != gateList.end() ){ simtime_t delay = SIMTIME_ZERO; for(; i != –gateList.end(); ++i){ delay = calculatePropagationDelay(i->first);
sendDelayed( static_cast<cPacket*>(msg->dup()),
delay, i->second );
}
delay = calculatePropagationDelay(i->first);
sendDelayed( msg, delay, i->second );
}
else{
coreEV << “Nic is not connected to any gates!” << endl;
delete msg;
}
}
}
