Abstract

Admission control plays an important role in providing Quality of Service (QoS) guarantees for wireless mesh networks (WMNs). Multipath routing can improve network performance in reliability and load balancing. However, when the multipath routing are adopted in 802.11-based WMNs, the transmission with bandwidth assurance is facing rigorous challenges. In this paper, a novel joint design of multipath routing and admission control protocol is presented, named MRAC. In MRAC, the multipath routing with bandwidth assurance is formulated as an optimization problem based on the analysis of available bandwidth and the bandwidth consumption. Based on the formulation, a heuristic solution is proposed to admit the data session through two parallel paths with bandwidth assurance. Through extensive simulations, the effectiveness of the MRAC is demonstrated in term of satisfying bandwidth requirement.
