Multi-path OLSR Performance Analysis in a Large Testbed Environment

چکیده
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, we 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).

One of the main challenges for mobile ad hoc networks is to design routing protocols that cope efficiently with dynamic network topologies. In this paper, we propose a new routing protocol called Multi-Path Optimized Link State Routing Protocol (MP-OLSR). The main idea is to use the sizeable amount of information collected by every node in OLSR in order to select not one but several reliable ro...

This paper provides a measurement-based performance evaluation of the Optimized Link State Routing (OLSR) protocol. Two versions of OLSR, OLSR-ETX and OLSR-ETT, are implemented and evaluated on a mesh network that we built from off-the-shelf commercial components and deployed within our department building. OLSR-ETX uses the Expected Transmission Count (ETX) metric, whereas OLSR-ETT uses the Ex...
