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.read more

Congestion-aware channel assignment for multi-channel wireless mesh networks
TL;DR: The channel overlapping and mutual interference matrices which model the frequency overlapping among different channels are introduced and show that in the presence of elastic traffic, the proposed DCACA algorithm increases the aggregate throughput and also decreases the average packet round-trip compared with the previously proposed Load-Aware channel assignment algorithm.

Detection of blackhole attack in a Wireless Mesh Network using intelligent honeypot agents
TL;DR: A novel strategy is proposed by employing mobile honeypot agents that utilize their topological knowledge and detect such spurious route advertisements that lure attackers by sending route request advertisements and the effectiveness of the proposed architecture is evaluated using simulation in ns-2.

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.
