A multi-path QoS multicast routing protocol with slot assignment for mobile ad hoc networks
چکیده انگلیسی

Mobile multimedia applications have recently generated much interest in mobile ad hoc networks (MANETs) supporting quality-of-service (QoS) communications. Due to the limited bandwidth of a wireless node, a QoS multicast routing is often blocked if there is not a single multicast tree with the requested bandwidth, even when there is sufficient bandwidth in the network to support the call. In this paper, a multi-path QoS multicast routing (MQMR) protocol for MANETs is proposed. The scheme offers dynamic time slot control using a multi-path tree (or a uni-path tree) to meet the bandwidth requirements of a call. The final multi-path QoS multicast tree meets the QoS requirements, and the aggregate bandwidth of the paths meets the bandwidth requirements of a call. To avoid the hidden terminal problem or insufficient bandwidth in the bandwidth reservation process, each destination uses a decision rule. Moreover, a bandwidth reservation scheme is used for selecting the reserved time slots on each node in the multi-path QoS multicast tree. Simulation results demonstrate the effectiveness of MQMR in reducing network blocking and improving the call success ratio.
