Multi-hop MAC: IEEE 802.11s Wireless Mesh Networks

Abstract

This chapter presents IEEE 802.11s, an emerging standard for wireless mesh networks (WMNs). IEEE 802.11s proposes multihop forwarding at the MAC level, which is a new approach for building WMNs. Traditional solutions for WMNs use network-level routing protocols to allow multihop forwarding among wireless mesh nodes. IEEE 802.11s specifies multihop MAC functions for mesh nodes using a mandatory path selection mechanism named HWMP (Hybrid Wireless Mesh Protocol) and also provides a path selection framework for alternative mechanisms and future extensions. This chapter discusses the emerging standard details and compares this new solution for WMNs to traditional ones.

“…Debora and Otto, et al (2008) [7] focused on path selection mechanisms and new frame formats, since these features are the most closely related to multi-hop forwarding at the MAC level. They also deals IEEE 802.11s emerging standard proposals, focusing on path selection mechanisms, and discuss and compare both layer-two and layer-three approaches for building WMNs.…”
