Joint Revenue-Based Call Admission Control and Routing in Wireless Mesh Networks
Various algorithms have recently been proposed to enhance the Quality of Service (QoS) in Wireless Mesh Networks (WMNs). In this paper, the authors investigate joint Call Admission Control (CAC) and routing in order to provide Quality of Service (QoS) in wireless mesh networks. Joint association of each mesh client with a mesh access point and multi-hop backhaul routing to the gateway, determine the availability of resources as to admit or reject a flow. They formulate a joint optimization problem, which maximizes the total revenue from all the carried connections in the network while taking into account the bandwidth constraints of access and backhaul links. In this regard, firstly they derive an optimal pricing policy that considers the complexity of the problem and the connection dropping probability.
