An Improved Channel Access Model for IEEE 802.11 WLANs
An Improved Channel Access Model for IEEE 802.11 WLANs is a scholarly work, published in 2013 in ''Journal of Engineering Science and Technology Review''. The main subjects of the publication include IEEE 802.11e-2005, Orthogonal frequency-division multiplexing, IEEE 802.11, IEEE 802, throughput, computer science, Inefficiency, computer network, channel, IEEE 802.11F, wireless ad-hoc network, wireless communication, and packet. In this paper, a robust channel access strategy is proposed.The research is motivated by the inefficiency of current IEEE 802.11WLAN systems.We adopt a dynamic allocation strategy that improves throughput efficiency in high-data-rate WLANs, by splitting the packet transfer of the system to speedup communication.The proposed model grants each node autonomous access to the pool of available resources using orthogonal frequency division multiplexing (OFDM) -a fourth generation wireless technology.The models for the system are derived and simulated with field data for both inbound and outbound traffics.Results obtained from the simulation represents best practices and yields better system performance compared to the existing IEEE 802.11WLAN systems.
