Abstract

In future wireless networks, the packet scheduler needs to support heterogeneous classes of traffic with different BER and other QoS requirements. In this paper, we proposed a modified BER scheduling scheme for CDMA networks by combining the existing WISPER scheme with a two-state Markov chain channel model. Four error-deal algorithms are used in this scheme. Simulation experiments based on NS-2 illustrate that the modified scheme can achieve both lower packet loss ratio and lower packet delay compared to the original WISPER scheme
