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 IEEE 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 als ....etc

Abstract
The user association mechanism specified by the IEEE 802.11 standard does not consider the channel conditions and the AP load in the association process. Employing the mechanism in its plain form in wireless mesh networks we may only achieve low throughput and ....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 learn ....etc

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 informati ....etc

WIRELESS MESH NETWORKS
Abstract
As various wireless networks evolve into the next generation to provide better services, a key technology, Wireless Mesh Networks (WMNs), has emerged recently. In WMNs, nodes are comprised of mesh routers and mesh clients. Each node operates not only as a host but also as a router, forwarding packets on behalf of other nodes that may not be within direct wireless transmission range of their destinations. A node can send and receive messages, and in a mesh network, a node also functions as a router and c ....etc
