Wireless Mesh Networks (WMNs) are gaining wide popularity as a flexible and cost-effective alternative to the traditional set of disjointed IEEE 802.11 Access Points (APs). Their all-wireless infrastructure is in fact suitable for both residential premises and for hardly accessible places. As a consequence, many companies have already put on the market their own WMN solutions. Yet, though most ...

This paper analyzes voice quality in terms of R-Factor and MOS in IEEE 802.11s Wireless Mesh Network (WMN). Another issue addressed in this paper is the effect of increasing nodes on voice transmission in wireless mesh network. The simulation model developed allows identifying the main reasons for voice quality degradation in Mesh network. Results show that voice quality measured in terms of R-...

Wireless mesh Network (WMN) is a multi hop low cost, with easy maintenance robust network providing reliable service coverage. WMNs consist of mesh routers and mesh clients. In this architecture, while static mesh routers form the wireless backbone, mesh clients access the network through mesh routers as well as directly meshing with each other. Different from traditional wireless networks, WMN...

As there is a growing need for the cost effective and highly dynamic large-bandwidth networks over large coverage area , the Wireless Mesh Network provide first step towards effective communication. A Wireless Mesh Network is one of the most advanced wireless network used for communication. During their operating period , the wireless mesh network may suffer from frequent link failure which res...

Many appealing multicast services such as on-demand TV, teleconference, online games and etc. can benefit from high available bandwidth in multi-radio multi-channel wireless mesh networks. When multiple simultaneous transmissions use a similar channel to transmit data packets, network performance degrades to a large extant. Designing a good multicast tree to route data packets could enhance the...

A Wireless Mesh Network is defined as an infrastructure network working with in as ad hoc mode.In a multi-hop wireless mesh network, it is always preferable to choose a path with higher throughput between a pair of source /destination nodes to fully exploit the network capacity. Since Wireless Mesh Networks have emerged as a practical solution for the wireless extension of the broadband interne...

Spatial-reuse Time Division Multiple Access or STDMA is a MAC technique that allows simultaneous reception and simultaneous transmission of signals in a wireless network. Simultaneous transmission and reception between different antennas that are geographically very close impose various constraints on the power transmitted by these antennas. This report will delve into how to determine a feasib...

Large-scale wireless testbeds have been setup in the last years with the goal to study wireless multi-hop networks in more realistic environments. Since the setup and operation of such a testbed is expensive in terms of money, time, and labor, the crucial question rises whether this effort is justified with the scientific results the testbed generates. In this paper, we give an answer to this q...

The wireless meshed technology is one of the most advanced technology and can be viewed as the technology of the future. This article deals with aspects like performance metrics i.e. delay, R-Factor and Mean Opinion Score (MOS) that have a direct influence on the performance of the wireless mesh network. In this paper voice quality is analyzed in terms of R-Factor and MOS in Wireless Mesh Netwo...
