Study on QoS Routing Protocol for New Wireless Mesh Networks

Abstract:

A QoS aware routing protocol for Wireless Mesh Networks is studied in this paper, the QoS metrics taken into account are bandwidth in our studies, end to end delay and stability of the routes. The routing metric reflects the maximal available bandwidth of a routing path, which is calculated based on the available bandwidth of mesh nodes with the consideration of the interference caused by the hidden terminals in WMNs. With the help of admission control decision, QRBC uses the routing metric in the route discovery process to find a QoS guarantee route for the real-time applications. The simulation results demonstrate that the QRBC protocol can find a less interfering and bandwidth guaranteed routing path for real-time flows.
