Performance comparison of BER-based routing protocols under realistic conditions

To face QoS constraints of multimedia applications, many researches focus on improving the standard MANET routing protocols. Nevertheless, only few works relating to the comparison of enhanced heuristics are available. In those literature, the comparison parameters are measured through simulations performed mainly under unrealistic conditions. In this paper, we compare BER-based enhancements of AODV and OLSR when they have to deal with mobility and multi-communication. We point out that link quality, influenced by obstacles in the propagation field, should be taken into account in MANET routing protocols enhancement simulations.
