How to Start Route Access Protocol Projects Using NS3

To start Route Access Protocols in NS3 that normally denotes to configure dynamic or static routing techniques to manage the route discovery, maintenance, and traffic management over network nodes. Although NS3 does not contain a protocol clearly named as “Route Access Protocol,” it has numerous routing protocols which permit for route discovery and access like AODV (Ad hoc On-Demand Distance Vector), OLSR (Optimized Link State Routing), DSDV (Destination-Sequenced Distance Vector), and DSR (Dynamic Source Routing). Moreover, we can be utilised static routing to describe routes among the nodes.

Below is a simple approach to replicate route discovery and access behavior within NS3 to utilize a mix of dynamic routing protocols and static routes to manage how traffic allows various paths.

Steps to Start Route Access Protocol Projects in NS3

  1. Install NS3

We can configure it with the below commands (assuming a Linux environment), if NS3 doesn’t install:

# Update system and install dependencies

sudo apt update

sudo apt install -y gcc g++ python3 python3-dev cmake libgsl-dev libsqlite3-dev

# Clone the NS-3 repository

git clone https://gitlab.com/nsnam/ns-3-dev.git ns-3

cd ns-3

# Configure and build NS-3

./ns3 configure –enable-examples –enable-tests

./ns3 build

  1. Create a New Script for Route Access Protocol Simulation
  1. In the NS3’s scratch directory, we make a new file like route_access_protocol_simulation.cc.
  2. Configure a simple network make use of dynamic protocols such as AODV or OLSR and static routes utilising the below example code.

Basic Structure of route_access_protocol_simulation.cc:

#include “ns3/core-module.h”

#include “ns3/network-module.h”

#include “ns3/internet-module.h”

#include “ns3/aodv-helper.h”

#include “ns3/olsr-helper.h”

using namespace ns3;

NS_LOG_COMPONENT_DEFINE(“RouteAccessProtocolSimulation”);

int main(int argc, char *argv[]) {

// Enable logging for debugging

LogComponentEnable(“UdpEchoClientApplication”, LOG_LEVEL_INFO);

LogComponentEnable(“UdpEchoServerApplication”, LOG_LEVEL_INFO);

// Create nodes representing routers and end devices

NodeContainer nodes;

nodes.Create(6); // Example with 6 nodes (routers and end devices)

PointToPointHelper p2p;

p2p.SetDeviceAttribute(“DataRate”, StringValue(“1Gbps”));

p2p.SetChannelAttribute(“Delay”, StringValue(“2ms”));

// Install point-to-point links

NetDeviceContainer devices01 = p2p.Install(NodeContainer(nodes.Get(0), nodes.Get(1)));

NetDeviceContainer devices12 = p2p.Install(NodeContainer(nodes.Get(1), nodes.Get(2)));

NetDeviceContainer devices13 = p2p.Install(NodeContainer(nodes.Get(1), nodes.Get(3)));

NetDeviceContainer devices24 = p2p.Install(NodeContainer(nodes.Get(2), nodes.Get(4)));

NetDeviceContainer devices34 = p2p.Install(NodeContainer(nodes.Get(3), nodes.Get(4)));

NetDeviceContainer devices45 = p2p.Install(NodeContainer(nodes.Get(4), nodes.Get(5)));

ipv4.Assign(devices34);

ipv4.SetBase(“10.1.6.0”, “255.255.255.0”);

ipv4.Assign(devices45);

// Set up a static route manually for testing route access

Ipv4StaticRoutingHelper staticRoutingHelper;

Ptr<Ipv4StaticRouting> staticRouting = staticRoutingHelper.GetStaticRouting(nodes.Get(2)->GetObject<Ipv4>());

staticRouting->AddNetworkRouteTo(Ipv4Address(“10.1.6.0”), Ipv4Mask(“255.255.255.0”), Ipv4Address(“10.1.4.2”), 1);

// Set up a UDP echo server on node 5 to test connectivity

UdpEchoServerHelper echoServer(9);

ApplicationContainer serverApps = echoServer.Install(nodes.Get(5));

serverApps.Start(Seconds(1.0));

serverApps.Stop(Seconds(10.0));

// Set up a UDP echo client on node 0 to communicate with the server

UdpEchoClientHelper echoClient(Ipv4Address(“10.1.6.2”), 9); // Server IP on node 5

echoClient.SetAttribute(“MaxPackets”, UintegerValue(5));

echoClient.SetAttribute(“Interval”, TimeValue(Seconds(1.0)));

echoClient.SetAttribute(“PacketSize”, UintegerValue(1024));

ApplicationContainer clientApps = echoClient.Install(nodes.Get(0));

clientApps.Start(Seconds(2.0));

clientApps.Stop(Seconds(10.0));

// Enable animation tracing

AnimationInterface anim(“route_access_protocol_simulation.xml”);

// Run the simulation

Simulator::Stop(Seconds(10.0));

Simulator::Run();

Simulator::Destroy();

return 0;

Explanation of the Code

  • Node Creation: We make six nodes signifying routers and end devices within a basic network topology.
  • Point-to-Point Links: These links associate nodes in sets, for probable route discovery and access, to make a small network including several paths.
  • Dynamic Routing Protocols:
    • AODV (Ad hoc On-Demand Distance Vector): A reactive protocol, which determines routes only when essential. For OLSR, DSDV, or DSR uncomment the helper line as we need to utilize these protocols.
  • Static Routing:
    • A static route is inserted at node 2, to describe a certain path attaining the subnet of node 5 via node 4.
  • UDP Echo Applications:
    • A UDP Echo Server is configured on node 5, analysing the connectivity.
    • A UDP Echo Client transmits packets on node 0 to the server, to experiment end-to-end connectivity and to confirm the route access.
  • Animation Tracing:
    • NetAnim: Makes an animation trace file like route_access_protocol_simulation.xml, which can be envisioned for monitoring node connections and packet flows within NetAnim.
  1. Build and Run the Simulation
  1. In the scratch directory, we can save route_access_protocol_simulation.cc.
  2. Go to a terminal, pass through to NS3 directory, and make the script:

./ns3 build

  1. Run the simulation:

./ns3 run scratch/route_access_protocol_simulation

  1. To envision the simulation, go to the made route_access_protocol_simulation.xml file within NetAnim:

netanim route_access_protocol_simulation.xml

Further Experimentation Ideas

To discover more routing access, we can deliberate:

  • Increase Network Size: Insert additional nodes and links to experiment how route discovery and access scale within a larger network.
  • Introduce Mobility: Create nodes mobile using RandomWaypointMobilityModel or another mobility model, to replicate a dynamic network in which routes often modify.
  • Compare Protocols: We can execute the simulation including various routing protocols such as AODV, OLSR, DSR, and DSDV and then examine performance parameters such as latency, packet delivery ratio, and route discovery time.
  • Simulate Link Failures: During the simulation, we can detach certain links to monitor how routes are re-established or modernized.
  • Measure Performance Metrics: Monitor performance parameters such as packet delivery ratio, end-to-end delay, and routing overhead to utilize FlowMonitor.

In the conclusion, we clearly explained simulation process and sample coding for Route Access Protocol projects using NS3 tool. Also we outline the further information on how these projects will perform in other tools.
