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.read more

Channel Assignment Exploiting Partially Overlapping Channels for Wireless Mesh Networks
TL;DR: This paper proposes a new channel assignment scheme named Channel Assignment Exploiting Partially Overlapping Channels (CAEPO), which can not only assign non-overlapped channels, but also exploit partially overlapping channels and effectively improves the network performance.

ALARM: an adaptive load-aware routing metric for Hybrid Wireless Mesh Networks
TL;DR: The ALARM routing metric, which is computed using the number of packets queued per wireless interface, offers an accurate representation of the traffic load, link quality, interference and noise levels and outperforms well-know routing metrics like ETT and WCETT under varying mobility and traffic load conditions in Hybrid WMNs.

Load-aware Traffic Engineering for Mesh Networks
TL;DR: A new Interference-Load Aware routing metric, ILA, is proposed that finds paths with reduced inter-flow and intra-flow interference to route the traffic through congestion free areas and balance the load amongst the network nodes.

The capacity of wireless networks
Piyush Gupta,P. R. Kumar +1 more
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
Matthias Grossglauser,David Tse +1 more
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
Sanjit Biswas,Robert Morris +1 more
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.
