We investigate the performance of UDP, TCP and voice in a static wireless multihop network experimentally and by simulation. Measurements are carried out in a network consisting of eight stations with IEEE 802.11b interfaces in a ring topology. We analyse the impact of hop count, packet size and collision avoidance mechanism on the performance metrics throughput, jitter and delay. The main observations are that the throughput decreases particularly over the first three hops and that the IEEE 802.11 collision avoidance mechanism generally decreases performance. Nevertheless, voice communication is possible over up to seven hops.
