Abstract :
The communication performance in wireless networks is often heavily influenced by failures caused by node mobility and radio disturbance. Proactive link-state routing protocols like OLSR and OSPFv3 with wireless extensions (WOSPF) are currently relying on slow re-convergence to restore successful packet forwarding. This may not be appropriate for particular applications, and it may cause instability during transient failures. Support for fast and local reroute should therefore be added as a feature to proactive link-state based routing protocols. In this paper, we discuss the challenges and requirements that are associated with such solutions. In addition, we evaluate and discuss to what extent recent developments for fixed IP routing can serve as solutions.
