Executive Summary

Multi-hop wireless communication is playing a key role in today's communication networks. Despite several advancements in communication protocols and technologies, QoS provisioning is still a challenging issue in multi-hop wireless communications. In this paper, the authors propose a novel scheduling mechanism based on resource reservation for guaranteeing the QoS performance of Real-Time SessioNs (RTSNs) in IEEE 802.11ebased Multi-Hop Wireless Networks (MHWNs). Since RTSNs are sensitive to end-to-end delay in addition to their throughput requirements, their scheme defines a novel bandwidth reservation mechanism which guarantees resources to high priority services (i.e., RTSNs) for meeting both the delay and the throughput requirements.
