IEEE 802.11s is the standard for WLAN(Wireless LAN) mesh networking. Wireless Mesh Networks (WMNs) have evolved as the key technology for next generation wireless networking. Energy consumption is increasing at an exponential rate with heavy growth in the number of smart devices. With this ever increasing demand for energy in every field coupled with the increase in carbon dioxide levels in the environment...
In multi-hop wireless mesh networks, the end-to-end throughput decays exponentially with the increase in hop counts. This is mainly due to the increase in successive spatial contentions. As a result, flows with longer hops suffer from bandwidth starvation and fair link access disparities along the path towards the gateway. In this paper, we first develop a theoretical reference model that can be used...
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,...
In wireless mesh networks (WMNs), a station (STA) often has a group of candidate access points (APs) to be associated with. How to select the most appropriate AP has been an open problem. In IEEE 802.11 standards, the STA simply chooses the one with the strongest RSSI. Since this AP selection strategy can cause severe network load unbalance, many new methods have been proposed. However, these solutions...
IEEE 802.11 wireless interface supports multiple transmission rates. It is an important problem how to select the transmission rate so that the throughput is maximized. In a wireless mesh network (WMN), nodes are stationary placed in general. The characteristic of each link will not change significantly over relatively long time. It is effective to assign fixed transmission rate which achieves the...
While WiFi was initially designed as a local-area access network, mesh networking technologies have led to increasingly expansive deployments of WiFi networks. In urban environments, the WiFi mesh frequently supplements a number of existing access technologies, including wired broadband networks, 3G cellular, and commercial WiFi hotspots. It is an open question what role citywide WiFi deployments...
We propose QoS-aware mesh deterministic access opportunities (MDAOPs) assignment algorithm for the IEEE 802.11s wireless mesh networks (WMNs). The WMNs can benefit from the mesh deterministic access (MDA) in terms of guaranteeing the QoS of the delay bounded traffic, mitigating the exposed node problem, and providing the fairness among best effort traffic flows. However, it is not considered that...
The Internet has revolutionized communication, education, commerce and information access for its users worldwide. Unfortunately, the lack of copper/fiber infrastructure in the rural areas of the developing world has prevented a large majority of the human population from reaping the benefits of the Internet. While the number of mobile subscribers in the developing world has more than quadrupled in...
Has the same problems as the traditional wireless LAN, wireless mesh networks (WMN) is anticipated to resolve the limitations and to significantly improve the performance of ad hoc network. In fact, differs from that of planning other wireless networks, such as cellular systems WLAN, design such a WMN to cover in a given region can be a non-trivial task. To solve the optimization problem of routing...
This demo aims at (i) validating the design choices we have made in conceiving and deploying the WING testbed, and (ii) showing the capability of out software toolkit to properly support heterogeneous multimedia applications. Additionally, the mesh networking toolkit's fault management features is demonstrated. We hope that our wireless mesh networking toolkit is considered by both researchers and...
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 networks (WMNs) have become a better alternative for extending wireless Local Area Networks (WLANs) to provide network coverage up to the furthest of far flung rural areas. This has been implemented by using a meshed backbone network interconnecting the mesh access points (MAPs) that manages each of the WLANs. The routing algorithms use the mesh backbone to establish inter-WLAN routes...
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...
