Abstract—Multicasting, which is a one-to-many communication, is motivated by the increasing importance of real-time and multimedia applications with different QoS requirements. The QoS metric considered in this work is the bandwidth. We approach this problem by assuming a common channel shared by all hosts under a TDMA (Time Division Multiple Access) channel model. In this paper, we propose a new TDMA-based QoS multicast routing algorithm--PSLCB, which aims at minimizing the number of forwarders so as to reduce bandwidth consumption. Simulations results show that compared with ODMRP, our proposed QoS routing algorithm improve packet delivery ratio and reduce end-to-end packet delay.
