NS2 Simulator Examples for Wired Networks with Tutorials for Beginners


NS2 Simulator Source Code for Wired Networks with Tutorials

NS2 (Network Simulator 2) source code and tutorials for wired networks, offering step-by-step instructions to help students and researchers simulate and analyze wired communication scenarios. Covering key concepts such as topology creation, link configuration, traffic generation, queue management, and performance evaluation, this tutorial introduces essential TCL scripting for building wired network simulations.

Users will learn to implement TCP/UDP protocols, congestion control mechanisms, and packet tracing to measure network performance metrics like delay, throughput, and packet loss.

With hands-on source code examples and real-world simulation scenarios, this resource equips learners with the necessary skills to design, test, and optimize wired network models using NS2 efficiently.

NS2 Simulator Source Code for Wired Networks

Wired Network Setup: NS2 includes the components for creation of wired network such as nodes, link of simplex and duplex type. Each link is configured with the parameters such as bandwidth, propagation delay and queue type. Packet limits of the queue can be mentioned. Data communication between nodes is configured with transport and application layer agents that are required to be attached to both sender and receiver nodes.
Protocols and Configuration parameters: Transport layer agents are TCP and its variants, TCPSink, SCTP, XCP, UDP, NULL, and LossMonitor. Application layer agents are CBR, FTP, ExponentialTraffic, ParetoTraffic, RealAudio, Video traffic and they have the options for packet size, data rate, data transmission interval, start and stop time of data transmission. Routing protocols such as RLM (Receiver-driven Layered Multicast) protocol, DV (Distance Vector), LS (Link State) routing protocol are applied in routing layer.
Wired Network Scenarios: Various wired network scenarios such as congestion, link failure, link recovery and attacks can be created dynamically at different instances of the simulation period with event-driven simulation capability of NS2.
Animation of Wired Network: Regarding the animation of wired network, it supports the labeling, coloring and shape of the nodes for differentiation. Similarly, links and packets can be shown with different colors. Orientation of nodes in the network topology can be mentioned in TCL script. It is also possible to drag and drop the nodes in NAM tool to view the network in a desired topological manner. Packets stored in the queue and packet drop can be viewed during animation. Properties of the packets and links can be seen if the links and packets are clicked in NAM. Ongoing network process can be annotated using trace annotate option and it will be displayed at the bottom of network animation window.
Trace file and AWK script for Wired Network: Trace file generated at the end of simulation follows a specific format for wired network that includes event type, time, nodes involved in it, and data specifications. It can be processed using the wired network specific AWK scripts for performance analysis.
