Evaluating voice traffic requirements on IEEE 802.11 ad hoc networks
This paper analyzes voice transmission capacity on IEEE 802.11 ad hoc networks by performing simulations related to delay, jitter, loss rate, and consecutive losses. We evaluate the influence of mobility on the number of sources transmitting voice. Another issue addressed in this paper is the effect of node density on voice transmission. Our simulation model has allowed us to identify the main reasons for voice degradation in ad hoc networks. Results show that voice transmission capacity degrades with mobility and network load, being more sensitive to high mobility due to link failures. The network capacity can easily experience a decrease of up to 60% on the number of voice transmissions on a multihop environment. We also show that node density is also relevant when considering voice transmission on multihop networks.
