[ndnSIM] Inducing waiting delay in nodes and no member named GetObject error

[lahmer ilyas]

Hi To get The position of a node you can do the following :
#include <ns3/mobility-module>
#include<ns3/core-module>

ns3::Ptr<ns3::Node> node = ns3::NodeList::GetNode(ns3::Simulator::GetContext());
ns3::Ptr<ns3::MobilityModel> mobility = node->GetObject<ns3::MobilityModel>();
ns3::Vector current = mobility->GetPosition();
std::cout<<"Node Position"<<current<<std::endl;

Hi,

unfortunately, I am not familiar with the mobility models of NS-3.

You can try to use the ScheduleWithContext method and see if that will work:

Thanks Spyridon i renamed the strategy and the .cpp and hpp names and
it
worked.
Also, i wanted to get the position of the nodes in the forwarding
strategy.
1.i tried directly using the
using namespace ns3;
using namespace fw;
Ptr<MobilityModel>model=GetObject<MobilityModel>();
Vector position= model.GetPosition();
-------------------------
error: 'GetObject' was not declared in this scope

2.also inducing delay using following:
Simulator::Schedule(Seconds(Ndelay),
&WaitStrategy::SendAfterDelay,pitEntry,outFace,interest);
void WaitStrategy::SendAfterDelay(shared_ptr<pit::Entry>&
pitEntry,const Face outFace,const Interest& interest)
{
this->sendInterest(pitEntry, outFace, interest);
}

---------------------------------------------------------------------------------------------------

gives error:
error: use of deleted function 'nfd::face::Face::Face(const
nfd::face::Face&)'
Simulator::Schedule(Seconds(Ndelay),
&WaitStrategy::SendAfterDelay,pitEntry,outFace,interest);
error: candidate is: void

nfd::fw::WaitStrategy::SendAfterDelay(std::shared_ptr<nfd::pit::Entry>&,

nfd::face::Face, const ndn::Interest&)
Thanks,
Raj
