Experiences with the ns-2 Network Simulator - Explicitly Setting Seeds Considered Harmful

by Martina Umlauft, Peter Reichl - in Proceedings of the 6th Wireless Telecommunications Symposium (WTS , 2007
"... The ns-2 network simulator is one of the most widely used packet network simulators. In version 2.1b9 its old random number generator was replaced by an implementation of MRG32k3a to fix sensitivity to seeds. Due to bad documentation and re-use of old scripts many people still use the old API functi ..."

Using the NS-2 Network Simulator for Evaluating Network on Chips (NoC)

by Muhammad Ali, Michael Welzl, Awais Adnan, Farrukh Nadeem
"... Abstract: Networks on chips (NoCs) have been introduced as a remedy for the growing problems of current interconnects in VLSI chips. Being a relatively new domain in research, simulation tools for NoCs are scarce. To fill the gap, we use network simulator NS-2 for simulating NoCs, especially at high ..."

Performance Analysis for Routing Protocols in MANETS by using NS2(Network Simulator)

by B. Nageswara Rao, B. N. S. Ramya Sri, K. Sumanjali, Ch. Sai, A. S. R. Raju
"... Abstract—A Mobile Ad-Hoc Network [MANETs] is a collection of wireless mobile nodes forming a temporary network without using any centralized access point, infrastructure, or centralized administration. In a MANET network topology can dynamically change in an erratic manner since nodes are free to mo ..."

Performance Modeling of TCP and UDP over Packet Radio Networks using the ns-2 Network Simulator

by Paul D. Wiedemeier, Ph. D - Proceedings of the 26th ARRL and TAPR Digital Communications Conference , 2007
"... Live network tests are often used to obtain performance metrics associated with the transmission of data using TCP and UDP over packet radio networks. However, only individuals who hold an amateur radio license issued by the United States Federal Communications Commission, as specified by Title 47, ..."

, Code of Federal Regulations, Part 97, are permitted to operate an amateur station. For this reason, we advocate using the ns-2 network simulator in academic environments to allow unlicensed students to evaluate the performance of packet radio networks. In this paper, we discuss four topics concerning

Enhancing the ns-2 Network Simulator For Near Real-Time Control Feedback And Distributed Simulation

by John S. Weir, Major Usaf, John S. Weir , 2009
"... A network simulator coupled with a visualization package enables the human visual system to analyze the results of network modeling as a supplement to analytical data analysis. This research takes the next step in network simulator and visualization suite interaction. A mediator (or run-time infrast ..."

A Performance Comparison of Multi-Hop Wireless Ad Hoc Network Routing Protocols

by Josh Broch, David A. Maltz, David B. Johnson, Yih-chun Hu, Jorjeta Jetcheva , 1998
"... An ad hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any existing network infrastructure or centralized administration. Due to the limited transmission range of wireless network interfaces, multiple network "hops " ma ..."

is available. This paper presents the results of a detailed packet-level simulation comparing four multi-hop wireless ad hoc network routing protocols that cover a range of design choices: DSDV, TORA, DSR, and AODV. We have extended the ns-2 network simulator to accurately model the MAC and physical
