My Internship at EPFL in Lausanne, Switzerland Doug Lundquist University of Illinois at Chicago 25 November 2020 1

EPFL École Polytechnique Fédérale de Lausanne n About 6000 students in seven schools, with most study areas in technology-driven fields n One of the world’s top universities in computer science, engineering, and communications n 25 November 2020 2

Laboratory for Computer Communications and Applications Perform basic and applied research in networking and related fields n Provide undergraduate and graduate teaching of networking and related disciplines n Perform technology transfer to established and start-up companies n 25 November 2020 3

Traffic and Network Simulation Environment (Tra. NS) Located at http: //trans. epfl. ch/ n Integrates traffic and network simulators to generate realistic VANET simulations n Combines SUMO (Simulation of Urban Mobility) and either Ji. ST/SWANS or NS-2, allowing vehicles to respond to information during the course of simulations n Can use real maps (e. g. , from US Census) n 25 November 2020 4

Tra. NS issues Designed to model short trips; vehicles appear at map edges, travel to some point, then exit the network n Interactivity difficult with Ji. ST/SWANS n Some bugs (quite possibly from SUMO), leading to vehicle “teleports” or moving outside maps n Map granularity not suitable for dense networks n 25 November 2020 5

Tra. NS v 2. 0 n New features Allows designating specific paths or chains of paths n Allows construction of maps by hand n n Old problems Occasional teleport bugs remain n Interactivity still problematic with Ji. ST/SWANS n n Demo: http: //wiki. epfl. ch/trans/documents/trans. ht m 25 November 2020 6

Work Accomplished Coded methods for converting Tra. NS output (and pre-generated mobility data) to a compact format for Ji. ST/SWANS n Provided suggestions which were incorporated into latest version of Tra. NS n Wrote a paper for IEEE APSCC (Taiwan, December 2008) using Tra. NS to generate vehicle flows on hand-drawn maps n Continuing research dialogue n 25 November 2020 7

Lausanne n Pros: Clean, safe n Many students n Most people speak English n n Cons: Expensive n Difficult to find housing n n Other: Many small lizards, no squirrels 25 November 2020 8

Recreation Close to France, Germany, Italy n Switzerland has mountains n 25 November 2020 9
