Qos- based rate allocation in wireless mesh networks
In this paper, we present a centralized algorithm for QoS based rate allocation in wireless mesh networks. The main objective is to find approach that also satisfy user-specified QoS constraints, specifically with respect to rate and delay demands. Our approach provides higher priority to real-time flows than elastic flows by reserving the necessary bandwidth for the former and fairly allocating the left-over bandwidth to the latter. We first consider the network with truthful nodes. Then we extend that to cases where nodes are selfish and non-cooperative. We propose the an efficient and protocol-compliant mechanism to incentivize nodes to be truthful. Although earlier algorithms in this area have demonstrated performance improvements in terms of QoS parameters, the proposed QoS based rate allocation approach provides a framework that guarantees QoS constraints are actually met over the network.
