TL;DR: Key challenges that are impeding the rapid progress of wireless mesh networks are pointed out and the feasibility of some state-of-the-art technologies/protocols for adequately addressing these challenges are discussed.
Abstract: Within the short span of a decade, Wi-Fi hotspots have revolutionized Internet service provisioning. With the increasing popularity and rising demand for more public Wi-Fi hotspots, network service providers are facing a daunting task. Wi-Fi hotspots typically require extensive wired infrastructure to access the backhaul network, which is often expensive and time consuming to provide in such situations. wireless mesh networks (WMNs) offer an easy and economical alternative for providing broadband wireless Internet connectivity and could be called the web-in-the-sky. In place of an underlying wired backbone, a WMN forms a wireless backhaul network, thus obviating the need for extensive cabling. They are based on multihop communication paradigms that dynamically form a connected network. However, multihop wireless communication is severely plagued by many limitations such as low throughput and limited capacity. In this article we point out key challenges that are impeding the rapid progress of this upcoming technology. We systematically examine each layer of the network and discuss the feasibility of some state-of-the-art technologies/protocols for adequately addressing these challenges. We also provide broader and deeper insight to many other issues that are of paramount importance for the successful deployment and wider acceptance of WMNs.

TL;DR: This paper abstracts the primary reliability requirements in typical industrial wireless mesh networks and defines three types of reliable routing graphs for different communication purposes and presents efficient algorithms to construct them and describes the recovery mechanisms in the event of component failures.
Abstract: 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 the primary reliability requirements in typical industrial wireless mesh networks and define three types of reliable routing graphs for different communication purposes. We present efficient algorithms to construct them and describe the recovery mechanisms in the event of component failures. Based on these graphs, data link layer communication schedules are generated to achieve end-to-end real-time performance. We demonstrate through extensive experimental results that our algorithms can achieve highly reliable routing, improved communication latency and stable real-time communication in large-scale networks at the cost of modest overhead in device configuration.

TL;DR: In this article, a wireless network comprises one or more sensor nodes and/or control nodes, and the sensor node transmits in response to a sensed event and a request from a control node.
Abstract: A node is suitable for a wireless network. A wireless network comprises one or more sensor nodes and/or one or more control nodes. In the wireless network, the sensor node transmits in response to a sensed event and/or a request from a control node. A transmission/routing of data between a sensor node and/or a control node may be subject to a policy constraint and a resource constraint.

TL;DR: The case for network coding as a unifying design paradigm for wireless networks is explored, by describing how it addresses issues of throughput, reliability, mobility, and management.
Abstract: Wireless networks suffer from a variety of unique problems such as low throughput, dead spots, and inadequate support for mobility. However, their characteristics such as the broadcast nature of the medium, spatial diversity, and significant data redundancy, provide opportunities for new design principles to address these problems. There has been recent interest in employing network coding in wireless networks. This paper explores the case for network coding as a unifying design paradigm for wireless networks, by describing how it addresses issues of throughput, reliability, mobility, and management. We also discuss the practical challenges facing the integration of such a design into the network stack.
