QoS for Wireless Mesh: MAC Layer Enhancements

Authors:
Mathilde Benveniste

Keywords: QoS, wireless mesh networks.

Abstract:
Wireless mesh networks present MAC design challenges beyond those of WLANs. Abundant hidden nodes increase the number of collisions. This, combined with the correlated access needed when forwarding a multi-hop flow, degrades QoS. MAC enhancements for meshes are presented in this paper that reduce latency for mesh traffic while promoting co-existence with nearby WLANs. Wider contention windows for backoff lower the risk of repeated hidden-node collisions, a spatial extension of the TXOP concept called 'express forwarding' clears multi-hop flows sooner, and a new mechanism called 'express retransmission' reduces collisions on retransmission. Simulation results show the potential benefit of the proposed enhancements. The issue of fairness is addressed, as well as preservation of QoS in nearby WLANs.
