General software features

Qolyester is the main in-the-field testbed for QOLSR over wireless Ad-Hoc networks.
It computes the best path with respect several metrics like capacity, delay, jitter, cost, loss probability, etc.
The goal of the current version is to be fully RFC 3626 compliant but without any QoS feature for the moment.

Context in which the software is used

This C++ software is at the heart of the QOLSR project, that is combining QoS with protocols OLSR, with the aim of dealing with metrics such as capacity, delay, jitter, cost in routing consideration with particular interest in IEEE 802.11-style MAC protocols due to their popular deployment in realistic wireless systems.

The major problems are the:

  • Interferences: flows that traverse the same geographical vicinity contend for the same wireless channel capacity;
  • Buffer size: After the saturation point the ad hoc network performance decreases;
  • Mac queuing time and service time based on the IEEE 802.11 binary exponential backoff algorithm;
  • Mobility.
