摘要

Analytical treatment of random multiple access systems with finite users and finite buffers remains a very complex problem due to the interfering nature of the queues through the shared medium. A new generalized analysis technique for buffered multiple access systems, called tagged user analysis (TUA), was recently proposed. TUA approach simplifies the analysis of buffered multiple access systems by exploiting the redundancy in the system and treating each user as a queueing system in equilibrium. In this thesis, TUA has been successfully applied to systems operating in wireless channels where fading and signal path loss might considerably affect the system performance. The performance of Slotted ALOHA and CSMA protocols operating in a Rayleigh fading channel is analyzed. We also consider the effect of path loss and random spatial distribution of users on the system performance. It is shown that TUA analysis is not complicated by the complexity of the underlying channel. The simulations results are also provided to compare with the analysis.
