Abstract
This paper investigates online QoS multicast routing in multi-channel multi-radio (MC-MR) wireless mesh networks (WMNs). In the proposed scheme, we assume that multicast sessions arrive dynamically, and each session has bandwidth and delay requirements. We investigate the acceptance of an arrived session in two steps. The first step devotes to establishing some paths from the source node to the receivers, where the selected paths satisfy delay constraint. In the next step, the multicast data is transmitted over the determined paths. In the proposed algorithm, multicast routing is performed using network coding to exploit its capacity boosting. The wireless broadcast advantage (WBA) is also exploited to diminish the amount of utilized bandwidth. Our simulation results confirm that the proposed algorithm improves the multicast acceptance rate compared to existing approaches.
