Wireless Mesh Networks (WMNs) have matured in recent years and the visibility of WMN deployments has attracted commercial operators to investigate this technology for applicability in their networks. Having their roots in the Mobile Adhoc Network (MANET) world and rather cheap off-the-shelf single-radio WLAN routers, WMN routing protocols were not designed for applicability in carrier-grade back-haul networks. For example, protocols such as OLSR or B.A.T.M.A.N. can not address the QoS-requirements of a modern operator back-haul network with its increasing demand for triple-play content. Although numerous solutions have been proposed to introduce QoS-awareness at the protocol or the technology level, traditional WMNs fail to meet commercial operator requirements in terms of reliability, traffic engineering and QoS guarantees. This chapter proposes a novel approach combining an IEEE 802.21-based control plane and an MPLS-based data plane. To provide support for ubiquitous high-bandwidth multi-media services, it seamlessly integrates unidirectional broadcast technologies such as DVB into the heterogeneous multi-radio WiBACK architecture.

Service Capability

With the number of applications increased in wireless mesh networks (WMNs), insufficient service capability is becoming a main obstacle. Meanwhile, cloud computing is an effective approach for organizing computing resource which can improve service capability remarkably. In this paper, framework of WMNs with cloud computing is proposed. Service capability of WMNs with cloud computing is judged and scored from 6 dimensions to make a composite comparison, which is shown cloud computing will be a promising approach for improving service capability in WMNs.

This paper investigates a novel joint problem of routing, scheduling, and channel allocation for single-radio multichannel wireless mesh networks in which multiple channel widths can be adjusted dynamically through a new software technology so that more concurrent transmissions and suppressed overlapping channel interference can be achieved. Although the previous works have studied this joint problem, their linear programming models for the problem were not incorporated with some delicate constraints. As a result, this paper first constructs a linear programming model with more practical concerns and then proposes a simulated annealing approach with a novel encoding mechanism, in which the configurations of multiple time slots are devised to characterize the dynamic transmission process. Experimental results show that our approach can find the same or similar solutions as the optimal solutions for smaller-scale problems and can efficiently find good-quality solutions for a variety of larger-scale problems.

Average Energy Consumption

Wireless mesh networks have numerous advantages in terms of connectivity as well as reliability. Traditionally, the nodes in wireless mesh networks are equipped with a single radio, but the limitations are lower throughput and limited use of the available wireless channel. To overcome this, the recent advances in wireless mesh networks are based on a multi-channel multi-radio approach. Channel assignment is a technique that selects the best channel for a node or to the entire network just to increase the network capacity. To maximize the throughput and the capacity of the network, multiple channels with multiple radios were introduced in these networks. In this work, algorithms are developed to improve throughput, minimize delay, reduce average energy consumption, and increase the residual energy for multi-radio multi-channel wireless mesh networks.
