A Wireless cellular Ad-hoc network is a collection of wireless mobile hosts that makes a momentary network with or without a centralized management or wired infrastructure. This is the era of growing smart phone technology people are dependent on the service provided by phone so in this scenario providing quality of service is essential task for service providers. Smart phone is movable device user...
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...
A wireless mesh network (WMN) is a collection of wireless network nodes that communicate among themselves. Unlike wireless local area networks, WMNs are self configuring systems, where each node can relay messages on behalf of others. This allows coverage of a much larger geographical area than if all nodes needed to be able to communicate directly with a central node. WMNs promise to deliver wireless...
Wireless mesh networks (WMNs) have the potentialities to greatly penetrate the marketplace in the next decade. They can be considered a hybrid between wireless infrastructure and ad-hoc networks; no other network infrastructure is needed other than the mesh points, thus providing flexibility in building and expanding the network, allowing for automatic discovery of neighboring nodes, increased reliability...
Wireless Mesh Networks (WMNs) are dynamically self-organized and self-configured, with the nodes in the network automatically establishing an ad hoc network and preserving the mesh connectivity. There are several features which might help to design an efficient routing protocol suitable for wireless mesh networks such as improved performance metrics, link or path optimization, mobility management,...
In this paper we present a research project of the research council of St-Joseph University (USJ) at its faculty of engineering (ESIB) in Beirut, Lebanon, in collaboration with professors at INRS-EMT, Montreal Canada. This project aims at addressing the issues of deployment of a Wireless Mesh Network (WMN) on parts of the Lebanese territory, supported by an already installed dense infrastructure of...
Wireless mesh networks have been attracting many users in recent years to achieve a wide-area wireless environment with flexible-configuration and low-cost properties by connecting base stations (mesh nodes) with each other via wireless connections. When the wireless mesh networks are used as an infrastructure for Internet access, all network traffic from mobile nodes go through a gateway node which...
Due to unstable link states, broadcasting transmission pattern, and interference between neighbor nodes, routing in wireless mesh network (WMN) is much more complicated and unpredictable than wired network. As the simplest and most primitive routing metric, hop count does not always work well in WMN where routing with least hop count does not bring the best performance. Recent research shows that...
In this paper, we propose an adaptive pacing scheme at the link layer for IEEE 802.11 based multihop wireless networks. Our objective is to improve the performance of higher layer protocols without any modifications to them. Our adaptive pacing scheme estimates the four-hop transmission delay in the network path without incurring any additional overheads, and accordingly paces the packets to reduce...
