Wireless Mesh Networks (WMNs) is an emerging and latest technology that is used to develop the new attractive applications for wireless network users. WMNs provide a good platform for many researchers to develop new innovative procedures and methods to improve the network performance in wireless enterprise backbone networks. WMNs have unique features like ease of deployment at low cost. By adding...
Single-radio mesh routers operating on a single channel suffer from low throughput due to collisions. Equipping mesh routers with multiple radios operating on non-overlapping channels can significantly improve the throughput. However, the assignment of channels to radios in a multi-radio mesh network is a challenging task. In this paper, we propose a channel assignment algorithm, TICA (Topology-controlled...
The Wireless Mesh Network (WMN) has already been recognized as a promising technology as broadband access network from both academic and industry points of view. In order to improve its performance, research has been carried on how to increase the number of simultaneous transmissions in the network while avoiding signal interference among radios. Considering WMNs based upon IEEE 802.11 b/g standards,...
Wireless Mesh Networks aim to provide high-bandwidth broadband connections to a large community and thus, should be able to accommodate a large number of users accessing the Internet. Due to high estimated traffic volume in Wireless Mesh Networks, scalability and fault tolerance become important requirements in algorithm design. We propose a Failure Recovery Mechanism (FRM) for the channel assignment...
Wireless mesh networks (WMNs) are comprised of nodes with multiple radio interfaces and provide broadband residential internet access or connectivity to temporal events. Our goal is to simplify the network deployment of such a mesh network, and towards that we are presenting procedures for automatic configuration and optimisation of the network. We first present an architecture framework that supports...
This paper focuses on how to determine an upper bound of maximum throughput from mesh clients to the Internet (or from the Internet to mesh clients) for multi-radio Wireless Mesh Networks (WMNs) under an interference-free assumption. In the case of the number of channels for assignment being high enough in a multi-radio WMN to meet the interference-free assumption, then the resulting solution can...
Wireless mesh nodes equipping multi-radio interfaces on each node and using multi-channel for transmission can greatly enhance the network performance. In this paper, a genetic algorithm, genetic tabu search, was presented to solve the channel assignment problem. The algorithm was evaluated by simulation on NS2 and compared with greedy and multi-radio unification protocol algorithms. Simulation results...
