ns-3 at Sigcomm 2011

Saturday, August 13, 2011

ns-3 has been used to produce research and educational results being presented at the 2011 ACM Sigcomm Conference being held from 15-19 August.

In the HomeNets 2011 workshop, Kandarej Piamrat and Patrick Fontaine present a coordinated architecture for home networks based on coordination between multiple access points.  Among their contributions is an integration of the ray tracing-based propagation loss model from the VOLCANO simulator.

In the Demos track, a team from Planete, INRIA and UC Santa Cruz demonstrate efficient content dissemination in heterogeneous networks prone to episodic connectivity.  This work integrates DTN-based networks with IP-based networks through a special gateway, and leverages the Tap Bridge capability in ns-3 enabling virtual machines to be integrated with ns-3 representations of wireless networks.

Also in the demos track was a Formally Safe Routing (FSR) toolkit for analyzing and implementing routing policies. The team from University of Pennsylvania, Carnegie-Mellon, and Princeton used ns-3 as the simulation engine for their work, with a Python-based visualizer.

In the Posters program, Stein Kristiansen, Thomas Plagemann, and Vera Goebel present a new node model for ns-3 that models the latency in real nodes, such as smartphones and other constrained devices, due to resource utilization and packet handling.  They describe how they have developed Service Execution Profiles based on instrumenting real devices and measuring them under test workloads.  The need for this modeling capability has been discussed recently on the developers list. Also in the poster session, Christof Leng, Max Lehn, Robert Rehner, and Alejandro Buchmann describe a testbed system for distributed systems research that uses ns-3 as one of the simulation components supporting real network applications within the testbed.

In the Education workshop, Harjot Gill,Taher Saeed, Qiong Fei, Zhuoyao Zhang, and Boon Thau Loo describe their experience in using ns-3 as courseware at the University of Pennsylvania. Among the projects completed was a DHT in 40+ rules using a declarative networking engine that was later incorporated to ns-3.
