Multi-hop wireless mesh network experience link-failure due to channel interference, dynamic obstacles etc. which causes performance degradation of the network in Wireless Mesh Networks. The paper proposes “Autonomously Reconfigurable Wireless Mesh Networks system based upon IEEE 802.11” for mr-WMN to recover autonomously in case the network failure occurs, to improve the network performance. T...

In this paper, we propose an efficient design of a heterogeneous mesh router, using network processors. Wireless Mesh Network (WMN) is a multi-hop wireless network, comprising two kinds of nodes-mesh routers and mesh clients. Microsoft Research has developed Mesh Connectivity Layer (MCL) for computers that use Windows operating systems. In MCL routing is done using a protocol called Link Qualit...

Support for multimedia quality of service (QoS) is critical and necessary requirement for next generation wireless networks. Wireless Mesh Networking is envisioned as an economically viable paradigm and a promising technology for supporting multimedia QoS. To maximize the aggregate utilization of traffic flows in a multi-hop wireless network, with constraints imposed both due to self-interferen...

Security is an important need in wireless mesh networks to give safe and shared information between wireless non-static nodes. In wireless network nodes has ability to act correctly and route the packets. Wireless mesh networks unusual method of producing,keeping and sharing information ability of mobile objects to show spontaneous and cheap adjusting arrangement itself.There are different type...

Wireless mesh networking is one of the most promising next generation network technologies. A wireless mesh network is a decentralized, self-organizing, self-configuring and self-healing multi-hop wireless network. In this thesis, we introduce the development, architectures, characteristics and applications of wireless mesh networks and present the existing channel assignments and routing proto...

Wireless LANs with their increased data rate become an attractive technology for connecting mobile users to the Internet. Efficient deployment of wireless LANs will require the ability to extend the wireless LANs coverage without the need to deploy a very large number of access points. Mesh based wireless LANs are an attractive solution to this problem. These networks extend the wireless LAN co...

−Wireless Mesh Networks (WMN’s) are achieving swiftly developing focus in current years, and are commonly recognized as an advanced option for nest era wireless networks. Contrasted with regular wireless and mobile networks, eg. Wi-Fi based wireless networks and mobile IP networks, WMN’s have the advantages of low price, easy implementation, self organization and self healing, and being compati...

In this paper we propose a dynamic update of the HWMP (Hybrid Wireless Mesh Protocol) proactive tree by changing dynamically the path request (PREQ) transmission interval, instead of a periodic fixed value as defined in the IEEE 802.11s draft. Indeed, we adapt dynamically the value of the PREQ transmission interval according to the wireless environment characteristics and to the amount of traff...

Wireless Mesh Network (WMN) has emerged as a key technology and found a great deal of interest for the researchers in the recent past. Hybrid Wireless Mesh Protocol (HWMP) is the default path selection (i.e., routing) protocol fully specified in the current draft D.1.06 of 802.11s for WMN. However, security in routing or forwarding functionality is not specified in the standard. As a consequenc...

The G-Mesh-Lab is a Wireless Multi-hop Network research project of the Freie Universität Berlin. As part of the Real World G-Lab Project, the focus of G-Mesh-Lab is to research and develop next-generation multi-hop network algorithms and protocols. It utilizes the DES-Testbed [1][2][3], which offers a sophisticated testing and evaluation framework, making it possible to define, schedule, run, m...
