In this paper, a Quality of Service (QoS) multicast routing protocol in Mobile Ad hoc NETworks (MANETs) by using directional antennas has been presented. Many important applications, such as audio/video conferencing, require the quality of service guarantee. Directional antenna technology provides the capability for considerable increase in spatial reuse, which increases the efficiency of communication. This paper studies TDMA-based time-slot allocation and directional antennas, and presents an effective algorithm for calculating bandwidth of a multicast tree. The authors also propose a novel on-demand QoS multicasting routing algorithm in TDMA-based mobile ad hoc networks using directional antennas. The simulation result shows the performance of this QoS multicast routing algorithm in TDMA-based mobile ad hoc networks using directional antennas.
