VoIP call admission control for last mile Wireless Mesh Networks

Abstract

IEEE 802.11 wireless mesh networks emerge as an alternative to provide an infrastructure for last mile access networks in remote areas. The meshed topology provides good reliability, low cost, market coverage and scalability. However due to the shared nature of wireless medium, which limits the available network bandwidth, it is necessary to implement an effective load control scheme that enable the use of wireless mesh networks for real-time applications. This work proposes a centralized admission control scheme to provide acceptable QoS for real-time applications. We demonstrate the usability of our admission control scheme to provide VoIP access for existing remotes areas connected via satellite link.
