Wireless Mesh Networks have been traditionally deployed to offer Internet access. Following the general trend of convergence, they must increasingly provide customers with communication services whose quality constraints are heterogeneous. For large scale deployments, access to the Internet is provided by multiple gateways installed at different points in the network. Each gateway may be connected...
Wireless mesh networks (WMNs) have recently emerged to be a cost-effective solution to support large-scale wireless Internet access. Handoff management plays an important role in WMNs in delivering Quality of Service to mobile users. In this paper, the handoff support in Internet-based infrastructure WMNs is investigated. Previous solutions on handoff management in infrastructure WMNs mainly focus...
This paper addresses the problem of optimal gateways selection and route selection to Internet in backbone wireless mesh networks (WMNs) where each mesh router (MR) is equipped with multiple radio interfaces and a subset of nodes serve as gateways to Internet. Several schemes have been proposed to route packets in WMNs or to select appropriate gateways to connect clients to Internet. However, most...
Inter-domain handoffs in wireless mesh networks (WMNs) must evaluate the resource conditions of the target handoff domain in order to make QoS handoff decisions. Performance degradations to either or both handoff and existing QoS-aware traffic occur when resources on gateways and mesh routers in the handoff domain are over-utilized, while on the other hand, global resources across domains might still...
How to select a proper access gateway from the several gateways of a wireless mesh networks(WMN) to connect to the Internet is one of the critical technologies which can improve the performances of WMN. A multi-path multi-gateway WMN anycast routing protocol based on an ant colony optimization (MMAMBA) was presented. In this protocol, gateway selection was taken as an anycast service, the distributed...
Wireless Mesh Network is mainly used to obtain Internet access, so most of the traffic converges to gateways. Due to the nature characteristic of WMN traffic model, gateways unavoidably become the bottleneck of the whole network. An anycast-based gateway selection model was proposed in this paper to solve the gateway selection problem. In this model, all the gateway nodes were abstracted as an anycast...
The Airborne Internet is envisioned to be a large scale multihop wireless mesh network of commercial passenger aircraft connected via long range highly directional air-to-air radio links. We propose a localized geographic load sharing technique to mitigate congestion in this network, taking into account the underlying link scheduling constraints with directional antennas. When forwarding packets for...
Recently, the Wireless Mesh Networks (WMNs) has gained momentum as a new broadband internet access technology, where most of the traffic is heading towards the gateway, as users need to access the internet and other wired resources. However, increasing the network capacity is still an open issue. One way to increase the network capacity is to equip each mesh router with multi-radio and turn each interface...
Wireless mesh networks (WMNs) have attracted increasing attention from the research community as a high-performance and low-cost solution to last-mile broadband Internet access. However, it remains an open challenge to provide mesh clients with efficient handoff among different mesh routers. In this paper, we address channel switching efficiency and load balancing capability during the handoff process...
Wireless mesh networks (WMNs) have recently emerged to be a cost-effective solution to support large-scale wireless Internet access. One important component of realizing large-scale WMNs is mobility management. Although a considerable amount of research on handoff management for cellular and Mobile IP networks has been proposed, handoff management for IP-based WMNs remains largely unexplored. Conventional...
Providing the required quality of service (QoS) for clients in a wireless mesh network (WMN) is a challenging task. This is due to the complex architecture of the WMN and unpredictable behavior of the wireless links and the intermediate nodes. This can be alleviated by introducing a cognitive mechanism within the WMN. In this paper, a WMN is developed, where the data traffic is forwarded in a cognitive...
To avoid congestion caused by some nodes overloaded and mesh points (MPs) becoming bottleneck in wireless mesh networks (WMNs), this paper proposed a new routing protocol called CLDSR-LB (cross-layer dynamic source routing protocol with load balancing). In order to avoid nodes overloaded, CLDSR-LB utilizes the idea of multi-metric and cross-layer and selects an optimal route by estimating the residual...
Nowadays public Internet access in residential areas is provided via fixed legacy wired infrastructure. Alternately, this paper analyzes a low cost, easy-to-install 802.11s wireless mesh based solution to ensure the transition to a network operating in a wireless environment. The presented simulations for the considered scenario take into account the quality of service provided to the end consumer,...
Multi-radio wireless mesh networks (MR-WMNs) are being increasingly deployed to provide affordable Internet access on large residential areas. MR-WMNs allow the supported mesh clients (MCs) to access the Internet gateway by multi-hop packet forwarding over the mesh routers (MRs), which can be equipped with multiple radio interfaces. In such a scenario, the routing protocol should (i) decide the address...
This paper evaluates our work of Scalable Proxy Mobile IPv6 (SPMIPv6) in a Wireless Mesh Network (WMN), which is a promising solution for ubiquitous Internet access and a wide range of applications. The aspects of scalability and signaling cost are evaluated respectively: the scalability is evaluated by numerical analysis while the signaling cost with respect to delay is evaluated by a virtualization-based...
Wireless mesh networks (WMNs) consist of mesh routers and mesh clients, where mesh routers have minimal mobility and form the backbone of WMNs. They provide network access for both mesh and conventional clients. Wireless mesh networks is put forward as one important technology of the access of various broadband. The integration of WMNs with other networks such as the Internet, cellular, IEEE 802.11,...
The wireless mesh network (WMN) is a novel wireless network architecture that puts several wireless routers into wireless ad hoc networks for mobile nodes to access the Internet. Due to the similarity in network topology between WMN and the Mobile ad hoc network (MANET), the routing algorithm from MANET can be adopted to WMN. Traditionally, the routing algorithms in MANET choose the shortest route...
