An R-ISMA integrated voice/data wireless information system with different packet generation rates

To realize wireless multimedia communication networks, new MAC (medium access control) protocols are required and the MAC protocols for the integration of voice/data are now being studied. This paper proposes a MAC protocol called R-ISMA (reserved idle signal multiple access) for the integration of voice/data in wireless information networks. To meet the requirements of wireless multimedia communication, the R-ISMA protocol can handle both voice traffic and data traffic from various sources, i.e., from terminals with different generation rates. We describe this protocol, then evaluate the system performance by using the TFA (transient fluid approximation) analysis. The R-ISMA is shown to perform better than the I-ISMA (ISMA for integrated services) protocol.
