An experimental study of VoIP performance in Wireless Mesh Networks using different mobility approaches

Performance evaluation and analysis of different VoIP over WLAN mobility schemes is essential in order to meet adequate QoS levels in VoWLAN deployments. This paper presents a study of real time voice communication QoS in terms of delay, jitter, throughput and packet loss between three different Wireless Mesh Network mobility schemes in a crowded 802.11 environment. We also discuss the feasibility of implementing Wireless Mesh Networks for VoIP in the presence of other 802.11 data-only networks. Other researches can also use our QoS measurements as guidelines for other mobility schemes performance tests.
