Wimax mesh networks for underserved areas
E. Sedoyeka1, Z. Hunaiti1, M. Al Nabhan2 and W. Balachandran2. Provide throughput similar to that of wired networks,. Connected to the Base Station (BS). Without relying on. Basic infrastructure like roads, tunnels or network. Existing connectivity demands for underserved areas..

This paper proposes a different approach, one that will. Lower the subscriber’s cost and hence help to bridge. The divide by using communities to set mesh networks. And eliminate the ‘middleman’. It provides insight into.

WiMAX, citing its mesh capabilities as the keyenabling factor in bridging the divide. The results. Facing developing countries are incorporated and used. (WSIS) defines digital divide as the unequal access to. The world’s inhabitants have access to ICT within their.

Self-reconfigurable wireless mesh networks kyu-han kim, member ...
Kyu-Han Kim, Member, IEEE and Kang G. Shin, Fellow, IEEE. Abstract—During their lifetime, multi-hop 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 enables. A multi-radio WMN to autonomously recover from local link. Failures to preserve network performance. By using channel and.

Radio diversities in WMNs, ARS generates necessary changes. In local radio and channel assignments in order to recover from. Failures. Next, based on the thus-generated configuration changes,. The system cooperatively reconfigures network settings among.

Routing in multi-radio, multi-hop wireless mesh networks
Routing in Multi-Radio, Multi-Hop Wireless Mesh Networks. We present a new metric for routing in multi-radio, multihop wireless networks. We focus on wireless networks with. Stationary nodes, such as community wireless networks.. The goal of the metric is to choose a high-throughput path. Between a source and a destination. Our metric assigns.

Weights to individual links based on the Expected Transmission Time (ETT) of a packet over the link. The ETT. Is a function of the loss rate and the bandwidth of the link.. The individual link weights are combined into a path metric. Called Weighted Cumulative ETT (WCETT) that explicitly.

Accounts for the interference among links that use the same. Channel. The WCETT metric is incorporated into a routing protocol that we call Multi-Radio Link-Quality Source. We studied the performance of our metric by implementing it in a wireless testbed consisting of 23 nodes, each. Equipped with two 802.11 wireless cards. We find that in.

Routing packets into wireless mesh networks
Rainer Baumann∗ , Simon Heimlicher∗ , Vincent Lenders† , Martin May∗. Abstract— Wireless mesh networks are a promising way to. Provide Internet access to fixed and mobile wireless devices. In. Mesh networks, traffic between mesh nodes and the Internet. Is routed over mesh gateways. On the forward path, i.e., from.

Mesh nodes to Internet nodes, for all mesh nodes only route. Information for one destination, the gateways, needs to be. Maintained. However, on the backward path from the Internet to. Mesh nodes, an individual route for every mesh node is required..

In this paper we investigate protocols for backward path routing. In wireless mesh networks. Using simulation experiments with. Realistic mobility patterns of pedestrians and cars in cities, we. Compare three protocols, each of which represents a routing.

Improving ieee 802.11s wireless mesh networks for reliable routing ...
Ji-Sun Jung, Keun-Woo Lim, Jae-Beom Kim, Young-Bae Ko. Abstract—Smart grid environments require high standard of. Reliable transmission technologies to support various types of. Electrical services and applications. This paper recommends the. Utilization of IEEE 802.11s based Wireless LAN Mesh Networks.

Infrastructure. 802.11s based mesh networks can provide high. Scalability and flexibility, along with low installation and. Management costs. We also describe some challenging issues of. The IEEE 802.11s WLAN mesh based smart grid networks, and.

Propose two novel methods for improving the routing reliability.. A simulation study using the ns-3 was conducted to evaluate the. Problems in the current mesh networks and prove the superiority. Keywords – Wireless Mesh Networks; Smart Grid; IEEE.
