Dynamics of generalized tree protocols and its application to delay-sensitive traffic control

A general multi-layer collision avoidance/resolution (MULCAR) random access protocol has been developed by the concept of tree expansion to comprehend the classification of multiple access algorithms/protocols in the literature. Applied to delay-sensitive traffic control, the dynamic behavior of MULCAR is analyzed in different operation modes assuming blocked traffic returns inactive. The system in each mode is shown to deliver its ultimate throughput and a have regular correspondence between the resulting average delay and the maximum number of granted subsets. We also highlight the distinct effect of each mode on the system performance
