Wireless mesh networks (WMNs) have emerged as a key technology for next-generation wireless networking. However, several challenging research issues need to be resolved. One of the most effective factors to be improved is the routing protocol used to be robust, scalable, secured and efficient. This paper aims to design and implement a routing protocol that improves the scalability of the WMNs. The...
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...
During their lifetime, multihop wireless mesh networks (WMNs) experience frequent link failures caused by channel interference, dynamic obstacles, and/or applications' bandwidth demands. These failures cause severe performance degradation in WMNs or require expensive manual network management for their real-time recovery. This paper presents an autonomous network reconfiguration system (ARS) that...
Wireless mesh networks (WMNs) provide an attractive method to provide Internet connectivity in developing regions. Traditional mesh routing protocols are designed to find high quality/throughput multihop routes in the network. However, these solutions do not consider constraints imposed by the capacity at the gateway, often the bottleneck in such rural area networks. In this paper, we demonstrate...
Wireless mesh networks usually deploy multiple gateways to enhance the capacity. This paper studies how to maintain forwarding paths in 802.11s wireless mesh network. A Multi-Gateway Multipath routing protocol (MGMP) is proposed to explore path diversity. MGMP constructs multiple paths between source and destination using a proactive tree architecture as HWMP. In order to make MGMP more efficient,...
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...
Wireless Mesh Networking (WMN) emerges as a new technology to reshape the broadband industry towards a more efficient and cost effective connectivity. The WMN has been the ideal technology for the next generation wireless community networks that offers efficient digital engagements and an ideal platform for promoting social partnerships over both urban and rural communities. This is essential for...
Cities around the world have planned and implemented large-scale wireless mesh network deployments. These mesh deployments are expected to provide broadband mobile access to the Internet at a low-cost to the user. This paper considers the fairness problem for nodes in multihop wireless mesh networks. Many existing approaches are unsuitable because they require modifications to the IEEE 802.11 MAC...
Multi-radio nodes in wireless mesh networks introduce extra complexity in utilizing channel resources. Depending on the configuration of the radios, bad mappings between radio to wireless frequencies may result in sub-optimal network topologies. Static channel assignments in wireless mesh networks have been studied in theory and through simulation but very little work has been done through experiments...
A single-channel wireless mesh backbone may suffer from capacity limitations since all the wireless routers share the same channel. A multi-channel broadband wireless mesh backbone may have different capacity. This paper addresses the problem of channel assignment with differentiated services to support the quality-of-service (QoS) in the wireless mesh backbone. We propose a novel, simple and yet...
Wireless Mesh Networks dynamically forms a network and each node connects and maintains a mesh network. The Mesh network is a hybrid WMNs, combined by two network mobilities which is the MANETs based Backbone WMNs and the non-MANET based Client WMNs. This research recommends a routing method that provides interoperability and effectiveness in the BWMNs and CWMNs combined HWMNs network. This method...
Wireless mesh networks (WMNs) comprise of mobile and static nodes which communicate wirelessly. WMNs have several unique features such as self-organizing, self-configuring and self-healing and are being used in many applications such as metropolitan area networks and disaster and rescue operations etc. Routing in WMNs is challenging as the network topology and connectivity in WMN are very dynamic...
WMNs are low-cost Internet access networks built on cooperative routing over a backbone composed of stationary wireless routers. In hybrid mesh WMNs both client mesh and backbone has ability to forward the data to destination. Many ad hoc routing protocols have been adapted to work in WMN without considering the differences between both technologies. Due to the differences between ad hoc network and...
Wireless mesh network (WMN) is a multi-hop wireless network with partial mesh topology, which can replace wired infrastructure backbone in a traditional wireless network, to wireless. It is an exciting new technology that has applications in defense, metro-area Internet access, and disaster management. WMNs are believed to be a highly promising technology and will play an increasingly important role...
Supporting user mobility is an important requirement for wireless mesh networks. We propose a relay-router buffering- and-forwarding scheme for supporting smooth handoff in the infrastructure wireless mesh networks. Our proposal is based on buffering packets at intermediate relay routers in the packets forwarding route and neighboring relay routers working in promiscuous mode which can overhear the...
Self-organization in wireless mesh networks is an emergent research area, which is becoming important due to the growing amount of nodes in a network. Consequently, arise the specific problem of manual configuration of individual nodes, as being either impossible or very expensive. So it is interesting the nodes be configured by themselves. In this paper, we propose an efficient architecture for self-organization...
Low-cost wireless routers are changing the way people connect to the Internet. They are also very cheap, albeit quite limited, Linux boxes. These attributes make them ideal candidates for wireless mesh routers. This paper presents a minimally invasive mechanism for redundant multipath routing in kernel-space to achieve high reliability with high throughput in a mesh network. This service is essential...
