Bandwidth-satisfied QoS multicast routing in TDMA-based mobile Ad hoc Networks

The need for supporting real time multimedia applications for users of Mobile Ad hoc Network (MANET) is becoming essential. The aim of this paper is to construct bandwidth-satisfied multicast tree for QoS routing in TDMA-based mobile ad hoc networks. The paper proposes an efficient path bandwidth calculation algorithm. An effective multicasting routing algorithm is presented to build a multicast tree among all the multicast members. Simulation results show that compared with MAODV, our proposed QoS routing algorithm can significantly improve the performance of QoS multicast routing in MANETs in terms of success ratio and average delay.
