Performance comparison and evaluation of AODV, OLSR, and SBR in mobile ad-hoc networks

Proactive routing protocols are mainly used in mobile networks since they are capable to distribute recent information very quickly. However, even reactive and hybrid protocols can be modified to achieve high end-to-end reliability in mobile networks while not increasing the end-to-end delay in a significant way. In this paper the performance of ad-hoc on-demand distance vector (AODV), optimized link state routing (OLSR), and the statistic-based routing (SBR) is simulated in various mobile scenarios with different traffic patterns. The protocols are compared with respect to reliability and routing overhead. The results show that the hybrid SBR protocol is able to achieve a high end-to-end reliability without frequent end-to-end route calculations or a large amount of overhead.
