Wireless Mesh Networks (WMNs) are ad-hoc networks where no infrastructure exists and where some of the participating nodes can also act as routers to forward traffic on behalf of others. WMNs have been proposed for various applications and can greatly vary in terms of size (from a handful of nodes to thousands) and complexity (static or mobile nodes, scarce or dense etc.). Efficient and robust IP...
This paper proposes LIBR, a routing protocol for Wireless Mesh Networks specially designed for linear topologies, i.e., topologies in which nodes are placed following a well-defined line-based pattern. This kind of topology may arise, for example, in power transmission lines, pipelines, roads, and railway lines. By exploring the intrinsic characteristics of these linear topologies, LIBR can achieve...
In a Wireless Mesh Network (WMN), the Mesh Access Points (MAPs) are connected to a wireless multi-hop mesh backhaul, which experiences constraints such as contention in the shared medium, bottleneck capacity at the backhaul, and unfairness to multi-hop MAPs. In this paper, we propose a cross-layer association scheme that takes access and backhaul link quality, network load, and backhaul contention...
Wireless mesh network management is more complex than wired network management mainly because of network resource constraints and link quality variability. Therefore, monitoring solutions for wired networks do not achieve satisfactory performance in mesh networks. There are several techniques and tools proposed in the literature for wireless mesh network management. Each of those techniques and tools...
As of today, many routing protocols for wireless mesh networks have been proposed. Nevertheless, quite a few take the high loss rate of control packets into account. This work analyzes the problem of consistent routing information among wireless network nodes. To accomplish this, we propose a metric to evaluate the level of inconsistency among routing tables. Our experimental analysis demonstrates...
Wireless mesh networks (WMNs) have emerged as a flexible and low-cost network infrastructure, where heterogeneous mesh routers managed by different users collaborate to extend network coverage. Several routing protocols have been proposed to improve the packet delivery rate based on enhanced metrics that capture the wireless link quality. However, these metrics do not take into account that some participants...
Increasing the capacity of wireless mesh networks has motivated numerous studies. In this context, link scheduling has been one of the most investigated mechanisms. However, the isolated use of scheduling mechanisms does not guarantee a significant increase in capacity independently of the routes followed by traffic. For this reason, the use of cross-layer optimization techniques involving joint use...
In Wireless Mesh Networks (WMNs) the meshing architecture, consisting of a grid of mesh routers, provides connectivity services to different mesh client nodes. The good performance and operability of WMNs largely depends on placement of mesh routers nodes in the geographical area to achieve network connectivity and stability. Thus, finding optimal or near-optimal mesh router nodes placement is crucial...
We present WiMFlow, a dynamic and self-organized flow monitoring framework in Wireless Mesh Networks. The protocol allows for an autonomic organization of the probes, with the goal of monitoring all the flows in the backbone of the mesh network accurately and robustly, while minimizing the overhead introduced by the monitoring architecture. A new mechanism that adapts the control messages emission...
