The introduction of heterogeneous wireless mesh technologies provides an opportunity for increased network capacity, broader coverage and higher quality of service (QoS). Each wireless device uses different standards, data formats, protocols, and access technologies. However, the diversity and complexity of such technologies pose challenges for traditional control and management systems. This article proposes a heterogeneous metropolitan area network architecture that combines an IEE 802.11 wireless mesh network (WMN) with a long-term evolution ....etc

Secure High-Throughput Multicast Routing in Wireless Mesh Networks



INTRODUCTION
WIRELESS mesh networks (WMNs) emerged as a promising
technology that offers low-cost high-bandwidth
community wireless services. A WMN consists of a set of
stationary wireless routers that form a multihop backbone,
and a set of mobile clients that communicate via the wireless
backbone. Numerous applications envisioned to be deployed
in WMNs, such as webcast, distance learning, online games,
vi ....etc

Wireless Mesh Networks Challenges and Opportunities
Overview
Gateways
Multiple interfaces (wired & wireless)
Mobility
Stationary (e.g. rooftop) most common case
Mobile (e.g., airplane, busses/subway)
Serve as (multi-hop) access points to user nodes
Relatively few are needed, (can be expensive)
Wireless Routers
Users
Typically one interface.

Abstract Wireless Mesh Network (WMN) has become an important edge network to provide Internet access to remote areas and wireless connections in a metropolitan scale. In this paper, we study the problem of identifying the maximum available bandwidth path, a fundamental issue in supporting quality-of-service in WMNs. Due to interference among links, bandwidth, a well-known bottleneck metric in wired networks, is neither concave nor additive in wireless networks. We propose a new path weight which captures the available path bandwidth informatio ....etc

Abstract We revisit the problem of computing the path with the minimum cost in terms of the expected number of page link layer transmissions (including retransmissions) in wireless mesh networks. Unlike previous efforts, such as the popular ETX, we account for the fact that MAC protocols (including the IEE 802.11 MAC) incorporate a finite number of transmission attempts per packet. This in turn leads to our key observation: the performance of a path depends not only on the number of the links on the path and the quality of its links, but also, ....etc
