Abstract:
Wireless Mesh Networks (WMNs) are networks that aim to establish hybrid wireless communications in areas with little or no telecommunication infrastructure available. The main motivation of these networks in Brazil and other developing countries, particularly in remote areas, is providing Internet access in places without commercial infrastructure and where the telecom operators have no economic interest due to its low demand. The idea is that a user in the network can forward the packets of distant users to the wired network connection point. Currently, wireless mesh networks use the IEEE 802.11 (WLAN) protocol due its availability and low-cost. However, IEEE 802.11 protocol favors the near users at expenses of a very low performance for distant users from the gateway node, connected to the wired network. The goal of this paper is to propose a mechanism using the IEEE 802.11e and QoS extension to provide a fairness network resource distribution for all participating WMN nodes, independent of their distance. The prototype was tested in simulation and the results demonstrated the proposal effectiveness in resource allocation in a wireless mesh network.
