This scheme is based on a mixture of movable-boundary WIMA protocol and speech activity process. Both voice and data traffic are handled on a packet reservation basis. The access slot of every uplink frame is allocated on the last slot to save the waiting time of queuing data. The expected data-packet delay for fixed-boundary WIMA, movable-boundary WIMA, and WIMA/SAD protocols are evaluated. Numerical results illustrate the dependence of performance on the system parameters, and demonstrate that the WIMA/SAD protocol provides a lower expected data-packet delay than the movable-boundary WIMA protocol for the values of voice-call completion probability ( μ v) less than 0.1. As μ v increases, the expected data-packet delay of the WIMA/SAD protocol approaches to movable-boundary WIMA protocol. The maximum data throughput of WIMA/SAD protocol has smaller variation than that of the movable-boundary WIMA protocol when voice-call completion ratio is changed.
