Abstract :
The capabilities of the cyclic reservation multiple access (CRMA) protocol for supporting mixed video and data traffic was evaluated by computer simulation. The results show that in order to obtain good performance and fairness between all the mixed stations, they should have similar requirements in terms of the number of slots that are requested at each reservation cycle. It is therefore important to reduce the variability by aggregating more slots for stations with short packets, and by transmitting long frames in successive cycles for long packets. The optimal selection of the low and high bound on the number of slots can significantly improve the performance of the CRMA network under mixed traffic conditions
