Node Placement in WMNs and Visualization of Evolutionary Computation Process Using WMN-GA System

2012 15th International Conference on Network-Based Information Systems, 2012
In Wireless Mesh Networks (WMNs), the performance of the network is affected by the location of mesh nodes. The placement of mesh nodes is an important design issue in deploying such networks. For a given grid size and a given number of mesh nodes, we use Genetic Algorithms (GAs) to find where to position the mesh nodes in order to maximize the ...

Gateways and performance of WMN

2010 2nd International Conference on Education Technology and Computer, 2010
Wireless Mesh Network (WMN) is emerging as key technology for the next generation network due to its features like providing broadband access with low cost and applicability to versatile areas. WMN's are basically multi-hop networks, in which data is forwarded to backbone through a gateway from the client nodes and vice versa.

Towards a Security Architecture for Hybrid WMNs

Proceedings of the 14th International Conference on Availability, Reliability and Security, 2019
Currently deployed Wireless Mesh Networks (WMNs) are mostly hybrid, i.e., some Mesh Points (MPs) also employ additional Access Point (AP) radios to connect non-mesh stations (STAs). Today's Wi-Fi security protocols are unsuited in the use case of WMNs, as they can neither derive key material without central authentication servers nor tolerate ...

Link scheduling for mmWave WMN backhaul

2017 IEEE International Conference on Communications (ICC), 2017
A new link scheduling approach for millimeter wave wireless mesh network is presented. The proposed link scheduling solution is designed to work together with a multiple overlapping spanning trees-based routing schemes on a mesh network topology. The link schedule computation will minimize the end-to-end delay along a subset of shortest-hop paths from ...

Analysis of WMN-GA Simulation Results: WMN Performance Considering Hot-Spot Scenario

2013 IEEE 27th International Conference on Advanced Information Networking and Applications (AINA), 2013
Wireless Mesh Networks (WMNs) are currently attracting a lot of attention due to their ability to provide cost-efficient broadband wireless connectivity. In our previous work, we evaluated WMN-GA system that is based on Genetic Algorithms (GAs) to find an optimal location assignment for mesh routers.

Secure and efficient handover protocols for WMNs

2013 IEEE 14th International Symposium on "A World of Wireless, Mobile and Multimedia Networks" (WoWMoM), 2013
Wireless Mesh Networks (WMN) consist of a wireless infrastructure of mesh routers which are connected to the Internet via mesh gateways. Mesh clients on the other hand connect to these routers. To make full use of the connectivity and services offered by a WMN, users should be able to securely hand over from one router to the next.

Defending selective forwarding attacks in WMNs

2008 IEEE International Conference on Electro/Information Technology, 2008
Wireless Mesh Networks (WMNs) have emerged recently as a promising technology for next-generation wireless networking to provide wide variety of applications that cannot be supported directly by other wireless networks. In WMNs, security is turning out to be a major concern and little attention has been paid to this topic by the research community.

Fair queueing for mmWave WMN backhaul

2016 IEEE 27th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2016
Static Wireless Mesh Networks (WMN) based on high capacity pencil-beam millimeter wave (mmWave) links offer an attractive solution for small cell backhauling in 5G networks. However, the delay targets in 5G are such that it is quite challenging to develop adequate link scheduling and routing mechanisms especially for a system composed of backhaul nodes
