On the Recovery Performance of Single-And Multipath OLSR in Wireless Multi-Hop Networks

Free registration required

Executive Summary

In this paper, the authors study and improve the recovery properties of single and multipath routing strategies when facing network failure situations. In particular, they focus their study on two MANET routing protocols: OLSR and its multipath extension MPOLSR. In various wireless multi-hop network environments, especially in multiple chain topologies, they define and seek to evaluate the latency introduced by these protocols to find a new path after a link failure. Theoretical estimations and simulation results show that, under dual chaintopologies, this latency can be too long and incompatible with the needs of loss and delay constrained applications.
