Optimized Link State Routing (OLSR) protocol is a leading proactive routing protocol for Mobile Ad-hoc NETworks (MANETs). Since the OLSR protocol in its standard version does not support multi-path packet forwarding, the authors have developed and implemented its multi-path extension. As a result of a slightly modified path computation algorithm and the application of backpressure Max-Weight Scheduling (MWS) policy, the MANETs can utilize the extended functionality based on OLSR. The experiment results presented in this paper compare the performance of the standard and extended OLSR versions in a large congested MANET (i.e., in large-scale DES-Testbed located at Freie Universitat Berlin).
