The last few years have witnessed an increase in energy consumption in Information and Communication Technology (ICT). Naturally, energy efficient solutions are becoming crucial for both local and wireless access networks. In this paper, we propose a new framework to support energy efficient management in Wireless Mesh Networks (WMNs). A key distinguishing feature of our solution is its online flow-based routing approach since existing flows are dynamically consolidated or even re-routed at fixed intervals according to live arrival and departure of mesh clients. The proposed solution is compliant with emerging Software Defined Networking (SDN) paradigm since it relies on a central controller to monitor and manage the network.To achieve this, we first formulate the problem as an integer linear program (ILP). As this problem is known to be N Phard, we then propose a simple yet efficient Ant Colony-based approach to solve the formulated ILP problem. Through extensive simulations, we show that our proposed approach is able to achieve significant gains in terms of energy consumption, compared to conventional routing solutions such as the Shortest Path (SP) routing, the Minimum link Residual Capacity routing metric (MRC) and the load balancing (LB) scheme. Specifically, we show that our approach reduces the energy consumption by up to 13%, 20%, and 52%, compared to MRC, SP and LB, respectively, while achieving the required QoS.

“…The sleep/wake-up states of wireless channels of the mesh router are independent from the network layer in general. However if AOC-MAC would co-operate with an energy-aware network-layer routing protocol (such as E-Mesh [2][3]), the performance in terms of balancing energy consumption and transmission performance of mesh routers can be further enhanced. For this reason, in AOC-MAC the sleep/wake-up states are indicated in the ATIM packets, which are forwarded to the routing protocols in the network layer.…”

AOC-MAC works in conjunction with an innovative energy-aware network-layer routing algorithm E-Mesh [2] [3], which extends the classic OLSR [4] routing algorithm. AOC-MAC informs E-Mesh about both connection condition and traffic delivery state and E-Mesh finds an optimal route for traffic delivery in terms of energy consumption level, network load and connection stability.…”

Abstract-Energy consumption has been a critical factor for mobile video applications. The quality of content delivery over wireless mesh networks consist of such devices is also considered important. Existing energy-aware research and industrial efforts focus on reducing high energy-consuming working periods of mesh devices, at the expense of decreasing the quality of video content. This article proposes an energy-quality-balanced solution AOC-MAC deployed at the MAC layer, working in conjunction with an energy-aware routing algorithm for wireless mesh devices. The simulation and perceptual test results are also presented in order to investigate the performance of the proposed solution. In particular, the impacts of content delivery data rate, mesh network topology scale and mesh device mobility are studied. Results demonstrate that AOC-MAC obtains up to 23% energy savings at roughly the same content delivery quality level, in comparison with the IEEE 802.11s MAC protocol.Index Terms-energy consumption, MAC-layer duty cycle management, perceptual testing, wireless mesh networks. I. INTRODUCTIONVER the past decades, the demand for support for data communications has increased significantly. With the advances in wireless mesh network technology, usage of wireless mesh devices has increased rapidly, accompanied by the growth of data traffic of high-level rich network services. High user Quality of Service/Experience (QoS/QoE) for such services is considered essential for further development of wireless mesh devices. It has been a challenge over the past Copyright (c) years to provide high quality video-related mobile services with QoS/QoE provisioning over wireless mesh networks, as the network resources involved, such as channel bandwidth and signal strength, are often constrained. The energy consumption of wireless mesh devices is another important research issue nowadays, as they often have limited power budgets while performing complex and energy-consuming application tasks. It is clear that energy-saving at the mesh points is needed for offering the ability to maintain high-quality video delivery service. Mesh points unnecessarily spend energy in many situations in existing wireless mesh networks, especially when they are idle waiting for incoming traffic. Based on such background, the fundamental task to achieve energy -effectiveness is to reduce the excess and useless work periods and to allow the mesh points to have a longer off-time while also maintaining good Quality-of-Service (QoS) levels.This article presents the detailed principles of the energy-aware MAC-layer solution AOC-MAC previously introduced in [1]. AOC-MAC is an energy-aware mesh router duty cycle management scheme for high-quality video deliveries over wireless mesh networks. It manages the sleep-periods of mesh devices in smart manner based on link-state communication conditions, reducing the energy consumption of mesh routers by extending their sleep-periods. AOC-MAC works in conjunction with an innovative energy-aware network-layer rout...

There has been an escalation in deployment and research of wireless mesh networks by both the business community and academia in the last few years. Their attractive characteristics include low deployment cost, a low-cost option to extend network coverage and ease of maintenance due to their self-healing properties. Multiple routes exist between the sender and receiver nodes because of the mesh layout that ensures network connectivity even when node or link failures occur. Recent advances among others include routing metrics, optimum routing, security, scheduling, cross-layer designs and physical layer techniques. However, there are still challenges in wireless mesh networks as discussed in this paper that need to be addressed. Crosslayer design allows information from adjacent and non-adjacent layers to be used at a particular layer for performance improvement. This paper presents a survey of cross-layer protocol design approaches applied to the IEEE 802.11 standards for wireless multi-hop mesh networks that have been proposed over the last few years for improved performance. We summarize the current research efforts in cross-layer protocol design using the IEEE 802.11 standard in identifying unsolved issues that are a promising avenue to further research.Section 3 presents some WMN protocol and design challenges that arise because of the architecture of WMNs. Section 4 gives a brief overview of CLD principles and presents the different cross-layer signalling architectures found in research to utilize information from different layers. The signalling architectures show that information can be used directly by non-adjacent or adjacent layers; by the use of a central database or server and any layer can use information from it; by interlayer signalling where the information passes through all layers and any layer can use it; and finally, by the use of information from a layer at a different node.Section 5 presents the survey on the application of CLD to WMNs to address some of the challenges in WMNs. The proposed cross-layer solutions are classified according to the cross-layer signalling architectures presented in Section 4. Many solutions are classified as using the networkwide cross-layer signalling architecture that includes among others routing metrics and soft computing techniques used in multi-path routing. Table III presents an individual summary of these articles. The table also presents the essence of the individual techniques. Table IV presents a comparison between the different approaches in terms of the modifications made to the layer architecture by these different cross-layer applications.The majority of the applications of CLD have been in the area of routing. In Section 6, we further assess the suitability of the proposed cross-layer protocols for use in three proposed use case scenarios. The comparisons, classifications and suitability by analysing the cross-layer protocol designing approaches are solely the views of the authors in this survey paper.Section 7 presents some future research directi...
