A QoS Multicast Routing Protocol with Mobile Prediction Based on MAODV in MANETs

Qos multicast routing is the process for upbuilding a tree which is rooted from the source node, contains all the multicast destinations and satisfies the QoS constrains. This paper introduces QoS routing problem and several mobile prediction strategies. It depicts QoS multicast model and proposes a QoS multicast routing protocol with mobile prediction based on MAODV (MPMRPQ). Simulation results demonstrate that the scheme is an effective approach to multicast routing decision with multiple QoS constrains. The proposed scheme can reduce multicast packet loss, network overload and optimize the delivery path.
