Abstract

In the wireless networks, a packet flow may experience channel errors and results in unsuccessful transmission The bursty channel errors can render the existing algorithms for wireless ad-hoc networks inapplicable. This study develops a fair scheduling algorithm to deal with channel error in wireless ad-hoc networks. The throughput of the network will be improved and the long-term fairness still maintained. The simulation results show our revised SZD algorithm achieves higher throughput and higher fairness than IEEE 802.11 MAC protocol and the original SZD algorithm.
