Background: Wireless mesh networks (WMNs) are a very attractive new field of research. They are low cost, easily\r\ndeployed, and a high-performance solution to last-mile broadband Internet access. In WMNs, admission control (AC)\r\nis one of the key traffic management mechanisms that should be deployed to provide quality of service (QoS) support\r\nfor real-time traffic.\r\nResults: In this paper, we introduce a novel admission control model, based on bandwidth and delay parameters,\r\nwhich integrates a dynamic link scheduling scheme. The proposed model is built on two different methods to access\r\nthe medium: on a contention-based channel access method for control packets and on a dynamic time division\r\nmultiple access (DTDMA) for data packets. Each time a new flow is admitted in the network, the WMN�s link\r\nscheduling is modified according to the flows� requirement and network conditions while respecting the\r\nsignal-to-interference-plus-noise ratio (SINR); this allows establishing collision-free transmissions.\r\nConclusions: Using extensive simulations, we demonstrate that our model achieves high resource utilization by\r\nimproving throughput, establishing collision-free transmission, as well as respecting requirements of admitted flows\r\nin terms of delay and bandwidth.
