This page is dedicated to the Tested installed at Universidade Federal Fluminense, Brazil.

Professor Luiz Magalhães and a group of students of Laboratório Midiacom, with the participation of Ricardo Carrano, from OLPC, built this testbed that is designed to study the behavior of a sparse mesh network, and answer the following questions:

  • Is a sparse network feasible? What are the practical distances and what can be expected in term of throughput and latency?
  • How does the shared Internet mechanisms (aka MPP) behave and what happens when you have multiple gateways?
  • What is the effect of mobility on a sparse network?
  • What is a good adaptive behavior to multicast/broadcast transmission rates?
  • What is the efficiency of the current multicast implementation?
  • How OLPC-Mesh compares to the current 802.11s implementation on the Linux Kernel?
