How to Calculate Network Served number of users in omnet++

To calculate the number of users served by a network in OMNeT++ has needs to monitor how many distinctive users (or devices) successfully interact with a network node, like a base station or access point, within a particular period and these performance metric is helpful for measuring the capacity and performance of the network particularly in scenarios that contains in the dynamic user behaviour and varying network conditions.

Steps to Calculate the Number of Served Users in OMNeT++:

  1. Set Up the Network Model:
    • Describe the network topology using NED files in OMNeT++ that contains nodes like base stations, access points, or routers, and user devices such as mobile nodes or clients and then configure the wireless or wired communication models as needed.
  2. Implement User Identification Logic:
    • Each user device (node) should have a distinct identifier, like an IP address, MAC address, or any other unique tag and this identifier will be used to monitor which users are being served by the network node.
  3. Track Served Users:
    • Retain a set or list of unique identifiers corresponding to the users that successfully interact with the network node. Each time a user sends or receives data through the node; enhance their identifier to the set if it isn’t already present.
  4. Calculate the Number of Served Users:
    • The number of served users is simply the size of the set of unique user identifiers at any given time.
  5. Log or Analyse the Number of Served Users:
    • We need to log the number of served users occasionally or at the end of the simulation to measure network performance.

Example Implementation: Served Number of Users Calculation

Below is the sample of how to calculate the number of served users in OMNeT++ using INET framework:

#include <omnetpp.h>

#include <unordered_set>

#include “inet/common/packet/Packet.h”

#include “inet/linklayer/common/MacAddressTag_m.h”

using namespace omnetpp;

using namespace inet;

class ServedUsersModule : public cSimpleModule {

private:

std::unordered_set<MacAddress> servedUsers;  // Set to store unique user identifiers

simsignal_t servedUsersSignal;               // Signal to record the number of served users

protected:

virtual void initialize() override {

servedUsersSignal = registerSignal(“servedUsersSignal”);

// Schedule the first check of served users

scheduleAt(simTime() + par(“checkInterval”).doubleValue(), new cMessage(“checkServedUsers”));

}

virtual void handleMessage(cMessage *msg) override {

if (msg->isPacket()) {

Packet *packet = check_and_cast<Packet *>(msg);

// Extract the MAC address (or other unique identifier) from the packet

auto macAddress = packet->getTag<MacAddressInd>()->getSrcAddress();

// Add the MAC address to the set of served users

servedUsers.insert(macAddress);

// Forward the packet to the next module

send(packet, “out”);

} else if (strcmp(msg->getName(), “checkServedUsers”) == 0) {

// Emit the number of served users

emit(servedUsersSignal, servedUsers.size());

EV << “Number of Served Users: ” << servedUsers.size() << “\n”;

// Schedule the next check

scheduleAt(simTime() + par(“checkInterval”).doubleValue(), msg);

} else {

delete msg;

}

}

virtual void finish() override {

// Emit the final number of served users at the end of the simulation

EV << “Final Number of Served Users: ” << servedUsers.size() << “\n”;

}

};

Define_Module(ServedUsersModule);

Explanation:

  • ServedUsersModule:
    • servedUsers: An unordered_set is used to store unique user identifiers (in this case, MAC addresses). The set automatically make sure that each user is counted only once.
    • servedUsersSignal: Registers a signal to emit the number of served users for logging or analysis.
  • initialize() Function:
    • Initializes the set and schedules the first check of served users.
  • handleMessage() Function:
    • Packet Handling: When a packet is established, the module extracts the MAC address of the sender and adds it to the set of served users. The packet is then forwarded to the next module.
    • checkServedUsers: Periodically compute the number of unique served users by releasing the size of the set and schedules the next check.
  • finish() Function:
    • Logs the final number of served users at the end of the simulation.
  1. Run the Simulation:
  • Compile and run OMNeT++ project. The simulation will monitor and log the number of unique users served by the network node.
  1. Analyse and Interpret Results:
  • The number of served users delivers insights into the capacity of the network node to manage multiple users. It is for the most part helpful in measuring the scalability and efficiency of the network under numerous load conditions.

Additional Considerations:

  • Dynamic User Behaviour: If users join and leave the network dynamically, consider updating the set correspondingly. For instance, we need to remove users from the set if they have not been active for a particular period.
  • Multiple Nodes: If the network has multiple nodes like base stations or access points, we want to monitor served users for each node individually or aggregate the outcomes.
  • Different Identifiers: While this example uses MAC addresses, we can use other unique identifiers like IP addresses or custom tags, depending on simulation’s requirements.

We had successfully calculated the network served number of users in OMNeT++ simulation that has create the network then apply the user identification logic to analyse the results. We plan to provide the additional data on how to calculate the network served number of users in other simulation scenarios.
