• As a standard of Wireless Mesh Networks, IEEE 802.11s has been emerged as a new MAC protocol and confronted with a commercialization phase. IEEE 802.11s adopts two kinds of MAC protocol, CSMA-based EDCA and TDMA-based MCCA. MCCA is a method to reserve bandwidth within 2-hop neighbors, but it cannot reserve the end-to-end bandwidth. So, in this paper, we suggests a Reservation-based HWMP (R-HWMP) satisfying the end-to-end QoS. The proposed protocol attempts to find a path satisfying the requested QoS first, and reserves the resource using MCCA. Through NS-2 simulation, we show that the proposed protocol guarantees the end-to-end QoS and outperforms to legacy contention-based DCF.
