Multicast QoS routing with minimum time slot allocation in IEEE 802.16 mesh networks

Abstract

IEEE 802.16 mesh network is extension of basic mode (PMP mode). It has features such as cost-effective deployment, increasing wireless coverage, easy implementation. To provide real-time services such as video conferencing or online game, network should provide QoS service. Routing is closely related to end-to-end delay and resource allocation. The goal of this paper is construct multicast tree which guarantees QoS with minimum number of time slot allocation. To achieve the goal, we consider link condition and interference in routing. Computational results show that proposed algorithm minimizes the number of time slot allocation. It also provides minimum delay.
