NS3 Mobile Computing Projects

NS3 Mobile Computing Projects is that technology that enables people to access network services anyplace, anytime and anywhere.In mobile computing, a set of distributed computing systems or service provider servers participate, connect, and synchronies through mobile communication protocols. We assist Engineering Students and Research Scholars in Implementing Ns3 Mobile computing Projects with best customer satisfaction.

Applications of Ns-3-mobile computing Projects:

• CDPD (Cellular Data Packet Data).
• Emergency applications.
• Entertainment.
• Government/ public services/ militaries.
• M-commerce etc.

Architecture of mobile computing:

Challenges faced in Ns-3-mobile-computing Projects.

• Reliability in presence of disconnections.
• Mobility/context aware applications.
• Security.
• Naming and locating.
• Transaction models.
• Routing data and messages.
• Data management.
• Two-tier transactions.

Sample code for mobile computing:

MeshTest::CreateNodes ()
{
nodes.Create (m_ySize*m_xSize);
YansWifiPhyHelper wifiPhy = YansWifiPhyHelper::Default ();
YansWifiChannelHelper wifiChannel = YansWifiChannelHelper::Default ();
wifiPhy.SetChannel (wifiChannel.Create ());
mesh = MeshHelper::Default ();
if (!Mac48Address (m_root.c_str ()).IsBroadcast ())
{
mesh.SetStackInstaller (m_stack, "Root", Mac48AddressValue (Mac48Address (m_root.c_str ())));
}
else
{ mesh.SetStackInstaller (m_stack);
}
if (m_chan)
{
mesh.SetSpreadInterfaceChannels (MeshHelper::SPREAD_CHANNELS);
}
else
{
mesh.SetSpreadInterfaceChannels (MeshHelper::ZERO_CHANNEL);
}
mesh.SetMacType ("RandomStart", TimeValue (Seconds (m_randomStart)));
mesh.SetNumberOfInterfaces (m_nIfaces);
meshDevices = mesh.Install (wifiPhy, nodes);
MobilityHelper mobility;
mobility.SetPositionAllocator ("ns3::GridPositionAllocator",
"MinX", DoubleValue (0.0),
"MinY", DoubleValue (0.0),
"DeltaX", DoubleValue (m_step),
"DeltaY", DoubleValue (m_step),
"GridWidth", UintegerValue (m_xSize),
"LayoutType", StringValue ("RowFirst"));
mobility.SetMobilityModel ("ns3::ConstantPositionMobilityModel");
mobility.Install (nodes);
if (m_pcap)
wifiPhy.EnablePcapAll (std::string ("mp-"));
}
MeshTest::InstallInternetStack ()
{
InternetStackHelper internetStack;
internetStack.Install (nodes);
Ipv4AddressHelper address;
address.SetBase ("10.1.1.0", "255.255.255.0");
interfaces = address.Assign (meshDevices);
