A modified BER scheduling scheme for wireless multimedia access control protocol
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
