TLDR
A detailed investigation of current state-of-the-art protocols and algorithms for WMNs is presented and open research issues in all protocol layers are discussed to spark new research interests in this field.
Abstract
Wireless mesh networks (WMNs) have emerged as a key technology for next-generation wireless networking. Because of their advantages over other wireless networks, WMNs are undergoing rapid progress and inspiring numerous applications. However, many technical issues still exist in this field. In order to provide a better understanding of the research challenges of WMNs, this article presents a detailed investigation of current state-of-the-art protocols and algorithms for WMNs. Open research issues in all protocol layers are also discussed, with an objective to spark new research interests in this field.

The capacity of wireless networks

TL;DR: When n identical randomly located nodes, each capable of transmitting at W bits per second and using a fixed range, form a wireless network, the throughput /spl lambda/(n) obtainable by each node for a randomly chosen destination is /spl Theta/(W//spl radic/(nlogn)) bits persecond under a noninterference protocol.

Mobility increases the capacity of ad hoc wireless networks

TL;DR: The per-session throughput for applications with loose delay constraints, such that the topology changes over the time-scale of packet delivery, can be increased dramatically under this assumption, and a form of multiuser diversity via packet relaying is exploited.

Routing in multi-radio, multi-hop wireless mesh networks

TL;DR: A new metric for routing in multi-radio, multi-hop wireless networks with stationary nodes called Weighted Cumulative ETT (WCETT) significantly outperforms previously-proposed routing metrics by making judicious use of the second radio.

ExOR: opportunistic multi-hop routing for wireless networks

TL;DR: ExOR chooses each hop of a packet's route after the transmission for that hop, so that the choice can reflect which intermediate nodes actually received the transmission, which gives each transmission multiple opportunities to make progress.
