Abstract
In the last decade numerous studies have been carried out into the transmission of VoIP traffic over wireless networks. However, only a few works have addressed the topic of supporting real-time audio applications on multi-hop IEEE 802.11 ad hoc networks from the perspective of simulations and testbeds. This paper presents the results of the implementation of a VoIP testbed on a multihop IEEE 802.11b ad hoc network with stationary hosts. The real-time audio transmission is evaluated using two different multihop routing protocols, AODV and OLSR. The quality of the voice transmission, using different codecs, is measured through different performance metrics such as end-to-end delay, delay jitter and sequence number error.
