Preliminary Performance Benchmarking of OLSRd2 Using Emulated TDMA MANETs and an ODR

摘要

The proactive routing algorithm OLSRd2 is popular in MANETs. The OLSRd2 routes are based on a Directional Air Time (DAT) metric that can be computed in several ways: three options have been considered here. For benchmarking with respect to the best possible performances, a so-called Omniscient Dijkstra Routing (ODR) algorithm is proposed. An investigation of the performance results of an acknowledged message service for a 24-node MANET using TDMA radios and OLSRd2 is presented. Round Trip Time and message Completion Ratio are computed based on real time emulations using the open-source EMANE framework. The emulated nodes move according to the realistic open-source Anglova scenario. A simple urban scenario with static nodes is also considered for comparison purpose. The preliminary investigations show that improving OLSRd2 is possible but appears to be very challenging as no single option stand out.
