NS2 and NS3 Network Simulation in India
NS2 (Network Simulator 2) and NS3 (Network Simulator 3) are the most widely used open-source network simulation platforms in academic research. From wireless sensor networks, Mobile Ad Hoc Networks (MANETs), and vehicular networks to 5G, IoT, SDN, and cognitive radio research, NS2 and NS3 form the simulation backbone of thousands of PhD and MTech projects in Computer Science, IT, and Electronics Engineering across India.
But working with NS2 and NS3 effectively requires more than downloading the software. Setting up the simulation environment on Linux, writing TCL scripts for NS2 or C++/Python modules for NS3, configuring network topologies, implementing routing protocols, and extracting and interpreting trace file outputs are all technically demanding tasks that require hands-on experience with these platforms.
At E-Clearby Research Consulting Pvt. Ltd., we provide expert NS2 and NS3 network simulation services for PhD scholars, MTech students, and researchers across India. We implement your network simulation scenario from scratch — topology, protocol, mobility model, traffic generation, and analysis — and deliver results that are accurate, reproducible, and ready for your thesis and journal paper.

What Our NS2 and NS3 Network Simulation Service Includes
Our NS2/NS3 engagement covers the complete network simulation workflow:
Simulation Scenario Design
We design the complete network simulation scenario based on your research objectives — number of nodes, network topology, mobility model, channel model, and traffic patterns.
NS2 TCL Script Development
For NS2-based research, we write complete, structured TCL simulation scripts configuring node properties, agents, applications, routing protocols, link parameters, and trace options.
NS3 C++ / Python Module Development
For NS3-based research, we develop simulation modules in C++ or Python implementing custom protocols, mobility models, traffic generators, and application layer logic.
Routing Protocol Implementation
We implement and compare standard routing protocols (AODV, DSDV, DSR, OLSR, OSPF, BATMAN) and custom or modified protocols as specified by your research objectives.
Network Topology Configuration
We configure wired, wireless, mesh, MANET, VANET, WSN, IoT, SDN, and hybrid network topologies scaled appropriately for your research scenario.
Mobility Model Integration
We configure mobility models for mobile network research — Random Waypoint, Gauss-Markov, Reference Point Group Mobility, and trace-based mobility aligned with your scenario requirements.
Traffic Generation
We set up CBR (Constant Bit Rate), FTP, VoIP, and custom traffic sources and sinks to simulate realistic network load for your evaluation.
Trace File Analysis and Performance Metrics
We extract and process NS2/NS3 trace files using AWK scripts (NS2) or built-in tracing (NS3), and calculate standard network performance metrics — packet delivery ratio, end-to-end delay, throughput, packet loss rate, routing overhead, energy consumption.
Result Visualisation
We generate performance comparison graphs using MATLAB, Python (Matplotlib), or GNUPlot comparing your proposed protocol against baseline methods across varying node counts, mobility speeds, or traffic loads.
Simulation Documentation for Thesis
We document the simulation setup, parameter table, and result analysis in academic format ready for your implementation chapter and journal paper.
Specialized Modules
Sub-Services
Module 01
MANET and VANET Simulation in NS2/NS3
Mobile Ad Hoc Network and Vehicular Ad Hoc Network research are among the most common applications of NS2 and NS3 in Indian PhD research. We implement MANET and VANET simulation scenarios configuring node mobility, routing protocols, channel models, and traffic, and compare protocol performance across varying network conditions. We support both standard protocol implementation and novel protocol modifications.
Module 02
Wireless Sensor Network (WSN) Simulation
For energy-efficient routing, clustering, data aggregation, and MAC protocol research in WSNs, we implement complete NS3 or NS2 simulation environments, configuring sensor node energy models, transmission ranges, sink node placement, and protocol behaviour, with energy consumption and network lifetime as primary evaluation metrics.
Module 03
IoT and 5G Network Simulation in NS3
For research in Internet of Things protocols, 5G network slicing, edge computing integration, and next-generation wireless communication, NS3 provides the required modularity and scalability. We implement IoT and 5G simulation scenarios using NS3's available modules and custom extensions, producing results aligned with current IEEE and Springer research standards.
Module 04
Software Defined Networking (SDN) Simulation
For SDN-based research in dynamic traffic routing, network virtualisation, and load balancing, we implement SDN simulation environments in NS3, configuring OpenFlow-compatible controllers, switches, and flow table management, and evaluate control plane performance metrics for journal paper comparison tables.
Module 05
NS2/NS3 Protocol Modification and Custom Implementation
If your research involves a novel routing, MAC, or transport layer protocol, or a modification of an existing standard protocol, we implement the custom protocol in NS2 TCL or NS3 C++, integrate it with the simulation environment, and produce comparative performance evaluation against the standard protocol it extends or replaces.
