Industrial wireless mesh networks are deployed in harsh and noisy environments for process measurement and control applications. Compared with wireless community networks, they have more stringent requirements on communication reliability and real-time performance. Missing or delaying of the process data by the network may severely degrade the overall control performance. In this paper, we abstract...
A lot of work has recently been published regarding metrics that could identify high quality paths in Wireless Mesh Networks (WMN). While results are encouraging, no optimal strategy has yet been identified that could estimate link quality and incorporate both the link reliability measurements as well as the bandwidth capacity. Furthermore, link estimation remains an open problem. Considering multi-user...
Wireless Mesh Networks (WMNs) research has matured in recent years and implementations are being tested around the world. In a WMN, participating nodes are automatically configured allowing them to communicate among their peers via multiple hops when no direct physical connectivity exists. Increasing demand for real-time multimedia content poses a challenge for the typical WMN routing protocols such...
Recently, opportunistic routing has gained much popularity for the ability to exploit the broadcast nature of the wireless medium with several practical protocols been proposed over wireless mesh networks (WMNs). These protocols usually add many mechanisms to introduce a dramatic increase in the overall network throughput, such as reliability promise and rate control. However, the evaluation of these...
Wireless Mesh Networks (WMN) provide a flexible and inexpensive way to expand network applications to mobile entities. However, high communication reliability demands can not be met by regular WMNs due to mobility and inherent properties of wireless communication. Failing links are common events which impose a major challenge for providing a dependable communication service. By the use of suitable...
The paper presents a monitoring system for carrier grade mesh networks. First, the system architecture, components and interfaces are described. Then the measured and discovered network parameters are discussed. A link prediction and trigger algorithm based on a modified mean-reverting diffusion process is proposed. The results from analysis show that this function can significantly enhance link reliability.
Wireless mesh network is a new type of network paradigm in which each node communicates to others to enhance network reliability and performance. Routing in wireless mesh network is a challenging task. Despite from the traditional routing, field based routing uses a little information to route the packets. Due to this characteristic, field based routing algorithms are inexpensive and robust, but such...
Wireless mesh networks (WMNs) have gained considerable attention in the recent years due to fast deployment, easy maintenance and low upfront investment compared with traditional wireless networks. Since WMNs are typically used as wireless backbones, they have the nature that the wireless communication is not stable. Hence, it is significant to protect them against link or node failures. Distribution...

In recent years wireless mesh networks have been deployed and grown in popularity in many metropolitan areas. The deployment of such networks has allowed clients to gain access to publicly available broadband networks. The lack of standards and support for multicasting over wireless mesh networks makes this area very challenging as well as providing much scope for improvement. For first time in this...
Wireless Mesh Networks (WMNs) are dynamically self-organized and self-configured, with the nodes in the network automatically establishing an ad hoc network and preserving the mesh connectivity. There are several features which might help to design an efficient routing protocol suitable for wireless mesh networks such as improved performance metrics, link or path optimization, mobility management,...
This paper studies probabilistically reliable multicast in wireless mesh networks (WMNs), utilizing MAC layer re-transmission and wireless broadcast advantage to improve both the multicast throughput and the delivery rate. We first present a new multicast routing metric which we call the expected multicast transmissions (EMT). EMT captures the effect of link packet delivery ratio, MAC layer retransmission...
