Establishing a trust relationship in decentralized wireless mesh networks (WMN) is an open question to date. In MANETs and cable bound meshed networks (like the Internet) there are a lot of proposals and solutions for trust establishment and for authentication. In this paper we examine those existing solutions and analyze them for their applicability to wireless mesh networks. We investigate th...

Equipping mesh nodes with multiple radios that support multiple wireless channels is considered a promising solution to overcome the capacity limitation of single-radio wireless mesh networks. However, careful and intelligent radio resource management is needed to take full advantage of the extra radios on themesh nodes. Flow-radio assignment and channel assignment procedures should obey the ph...

Wireless mesh networks (WMNs) promise to increase high-speed wireless property on the far side what's attainable with the present WiFi-based infrastructure. However, their distinctive field options leave them notably prone to security threats. During this article, we tend to describe numerous varieties of refined attacks launched from adversaries with internal access to the WMN. We tend to any ...

Stream control has recently attracted attentions in the research of MIMO wireless networks as a potential way to improve network capacity. However, inappropriate use of stream control may significantly degrade network capacity as well. In this paper, we provide the first formal study on stream control scheduling in MIMO wireless mesh networks. We derive the theoretical upper bound on network ca...

ZigBee wireless mesh technology makes wireless sensor and control network applications practical. Cost-effective, simple-touse, capable of very long product functionality from a pair of standard alkaline cells, it is meant for developers who want either to get rid of the tether that their product must use or provide a new level of functionality to their products with wireless communications. Th...

Deploying ad-hoc wireless mesh networks for emergency services is a popular topic. One of the main challenges in these networks is to overcome the performance hit due to the interference that is inherent to 802.11 wireless technology. A possible solution is to use multiple interfaces and multiple channels throughout the network in order to minimize this interference. In this paper, we will desc...

Wireless communication technologies divide their available spectrum into pre-defined channels. Some wireless technologies, such as the IEEE 802.11b/g, define their channels in such a way that adjacent channels share the spectrum. When two distinct channels share some part of their spectrum, simultaneous transmissions on these channels cause what is known as the adjacent channel interference. Fo...

The paper presents a performance study of wireless MESH networks in the context of the convergent transmission. Nowadays, the integration of voice, video and data is becoming the norm. However, the wireless LAN environment, and especially MESH technology is an unfriendly environment due to its characteristics. Therefore, the impact of the size of transmitted frames to delays in the network base...

The community notion can be exploited as a rational concept leading users to cooperate in sharing resources on Wireless Mesh Networks. We propose a novel concept for self-organizing networks, where multiple entities (network elements or users) collaborate to achieve common goals, and in particular, to establish the basic connectivity and service delivery infrastructures. The resulting architect...
