dc.description.abstract	Voice over IP (VoIP) over Wireless Mesh Network (WMNs) has become a topic of great interest in both enterprise and research arena. The IEEE 802.11 standard is the most popular Wireless LAN standard for extending the access point (AP) based network. However, it does not provide guaranteed quality for real-time applications such as VoIP. Besides, with the large number of injected flows in WMNs, only a handful of these packets can be supported due to protocol overhead, packet collision and Interferences. In this paper, a link-based aggregation is proposed and its performance improvement is compared with those of fixed aggregation and performance under standard access network. Simulation results show that the proposed aggregation scheme increases the number of supported flow while also reducing end-to-end delay, jitter, and packet loss of VoIP in WMNs. © 2008 ESRGroups.	en
