Channel state dependent resource scheduling for wireless message transport

This paper discusses radio resource scheduling algorithms for wireless message transport over a burst-error channel. In high-speed wireless access networks, multipath fading or shadowing would cause burst packet errors which are no longer recovered by retransmissions or forward error corrections, thereby imposing a serious impact on the utilization of the wireless channel. Channel state dependent (CSD) resource scheduling algorithms are designed to utilize the channel status to improve the comprehensive performance. Computer simulations are carried out to evaluate the scheduling algorithms in terms of the average of allocation plus transfer delay, the average of throughput, the variance of throughput, and the utilization of resources. Our results show that by employing the CSD mechanism, significant improvement in the performance can be achieved
