X. CONCLUSION
In this paper we have presented a performance analysis of the Wireless Integrated Multiple Access (WIMA) protocols. These schemes, which combine the pure-reservation NIFFL are especially well suited to satellite networks and to highspeed
wireless terrestrial networks in which the round-trip propagation delay is greater than the data-packet duration, although they are also appropriate for environments in which propagation delay is less than a packet duration. The techniques  we have developed to exploit the structural properties
of the two-dimensional first-order Markov chain that  characterizes this scheme have been shown to permit the  efficient and accurate evaluation of data-packet delay and  voice-call blocking probabiliy. Performance results illustrate  the dependence of performance on system parameters, and  demonstrate the improved performance that can be achieved  through the use of the movable-boundary version as compared  to the fixed-boundary version. Trade-offs between data-packet  delay and voice-call blocking probability show the importance
of the parameter Vmax, the threshold used to control access of  voice calls to the system.
