Abstract: Establishing quality of service (QoS) provisions in multirate multihop wireless mesh networks (WMNs) is a challenging task. Locating effective admission control is the foremost need to efficiently utilise the scarce network resources and provide QoS guarantees. In this paper, we propose an Estqos methodology comprising two phases. Phase 1 (ESTAB) computes the available bandwidth of a node considering the hidden terminals' presence. We build an analytical model for ESTAB phase. Phase 2 (ADMISSIONCONTROL) consists of an effective admission control algorithm which defines a data rate adaptive scheme for non realtime flows to ensure efficient use of the channel bandwidth. On the other hand in case of realtime flows, the admission control algorithm ensures that the channel is not overloaded and the delay constraint is satisfied.

Keywords: QoS; quality of service; admission control; available bandwidth; multirate WMNs; wireless mesh networks; multihop WMNs; channel overload; delay constraints.
