Comparison studies of OSPF-MDR, OLSR and Composite Routing
Jin Fang, Tom Goff, Guangyu Pei · 2010
In this paper, we investigate the benefits and tradeoffs among various routing strategies used in Mobile Ad Hoc Networks (MANET). In particular, we compare the performance of OSPF-MDR, OLSR, and Composite Routing. Our composite routing implementation is based on further extensions of OSPF-MDR that employs OLSR as the sub-IP MANET routing protocol. The performance evaluation was conducted on an emulation test-bed that utilizes the light-weight Linux network stack virtualization, namely network namespaces. The performance results show that OLSR outperforms OSPF-MDR. As a result, composite routing can leverage OLSR to achieve better network performance than OSPF-MDR with less overhead. Furthermore, composite routing can significantly reduce routing updates to legacy networks due to MANET dynamics (by about 95% under high mobility).
