Time-Driven Access and Forwarding in IEEE 802.11 Mesh Networks

Abstract

Various solutions based on both prioritization and resource allocation have been proposed in the literature and standard bodies to support end-to-end Quality of Service (QoS) in wireless multihop scenarios. However, their performance is not satisfactory in terms of achievable overall network throughput and tradeoff between end-to-end delay and network utilization. This paper proposes Time-driven Access and Forwarding (TAF), a novel multilevel solution to guarantee deterministic end-to-end QoS for real-time traffic and improve overall network throughput and utilization in 802.11 mesh networks.
