TL;DR: A comprehensive survey on a number of research studies that propose various channel assignment techniques to extract the best performance from a multi-radio wireless mesh network and categorizes the techniques and presents an exhaustive comparison among them.
Abstract: With the advent of multiple radio interfaces on a single device, wireless mesh networks start to achieve significant improvement in network capacity, latency, and fault tolerance. The improvement is achieved through concurrent transmissions over different channels utilizing the multiple radio interfaces. However, the introduction of different channels over multiple radios on single mesh node compels to retrospect different issues such as interference, channel diversity, and channel switching from novel perspectives. Due to these novel perspectives, conventional channel assignment techniques proposed for single-radio wireless mesh networks are not generally applicable to the multi-radio cases. Consequently, we have to reconsider the different issues while making a tradeoff among all the available channel assignment options to extract the best performance from a multi-radio wireless mesh network. There are a number of research studies that propose various channel assignment techniques to extract the best performance. In this paper, we present a comprehensive survey on these studies. First, we point out various design issues pertinent to the techniques presented in the studies, and adopt the issues as the basis of our further discussion. Second, we briefly describe several important already-proposed channel assignment techniques. Third, we present a number of channel assignment metrics that are exploited by the already-proposed techniques. Then, depending on the considerations in these techniques, we categorize the techniques and present an exhaustive comparison among them. Nevertheless, we point out a number of real deployments and applications of these techniques in real scenarios. Finally, we identify several open issues for future research with their current status in the literature.

TL;DR: It is discussed how these wireless technologies, being either standard or proprietary, can adapt to IoT scenarios (e.g., smart cities and smart agriculture) in which the heterogeneity of the involved devices is a key feature.
Abstract: The Internet of Things (IoT), being a “network of networks”, promises to allow billions of humans and machines to interact with each other. Owing to this rapid growth, the deployment of IoT-oriented networks based on mesh topologies is very attractive, thanks to their scalability and reliability (in the presence of failures). In this paper, we provide a comprehensive survey of the following relevant wireless technologies: IEEE 802.11, Bluetooth, IEEE 802.15.4-oriented, and Sub-GHz-based LoRa. Our goal is to highlight how various communication technologies may be suitable for mesh networking, either providing a native support or being adapted subsequently. Hence, we discuss how these wireless technologies, being either standard or proprietary, can adapt to IoT scenarios (e.g., smart cities and smart agriculture) in which the heterogeneity of the involved devices is a key feature. Finally, we provide reference use cases involving all the analyzed mesh-oriented technologies.

TL;DR: The experimental results showed the efficiency of the GAs for computing high quality solutions of mesh router nodes placement in WMNs and the size of the giant component is considered here as a criteria for measuring network connectivity.
Abstract: 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 to such networks. In this work we propose and evaluate Genetic Algorithms (GAs) for near-optimally solving the problem. In our approach we seek a two-fold optimization, namely, the maximization of the size of the giant component in the network and that of user coverage. The size of the giant component is considered here as a criteria for measuring network connectivity. GAs explore the solution space by means of a population of individuals, which are evaluated, selected, crossed and mutated to reproduce new individuals of better quality. The fitness of individuals is measured with respect to network connectivity and user coverage being the former a primary objective and the later a secondary one. Several genetic operators have been considered in implementing GAs in order to find the configuration that works best for the problem. We have experimentally evaluated the proposed GAs using a benchmark of generated instances varying from small to large size. In order to evaluate the quality of achieved solutions for different possible client distributions, instances have been generated using different distributions of mesh clients (Uniform, Normal, Exponential and Weibull). The experimental results showed the efficiency of the GAs for computing high quality solutions of mesh router nodes placement in WMNs.

TL;DR: In this article, a system and methods for wireless computing devices to become mesh member nodes within a self-configuring mesh network includes mechanisms for neighbor discovery and sharing of a common topology database including mesh topology and mesh network information.
Abstract: A system and methods for wireless computing devices to become mesh member nodes within a self-configuring mesh network includes mechanisms for neighbor discovery and sharing of a common topology database including mesh topology and mesh network information. Each mesh node may use the topology database to determine optimized routing paths within the mesh network. Mesh member nodes are configured to detect and communicate topology changes and measured mesh network attributes to other members of the self-configuring wireless network.

TL;DR: In this paper, a self-timed message routing chip is coupled to each processor node, thereby forming a two dimensional mesh of message routing chips, and data can broadcast through the mesh routing chips to a row, a column, or a matrix of nodes.
Abstract: A method and apparatus providing for data broadcasting in a two dimensional mesh of processor nodes is disclosed. In accordance with the present invention, a self-timed message routing chip is coupled to each processor node, thereby forming a two dimensional mesh of message routing chips. Broadcasting originates from a corner node, and data can broadcast through the mesh routing chips to a row, a column, or a matrix of nodes. The mesh routing chips, together, form a self-timed pipeline with each individual message routing chip having broadcasting hardware which provides for the forking of a message within that particular message routing chip. The self-timed forking of a message within individual message routing chips directly supports data broadcasting within the two dimensional mesh.
