Per connection delay analysis of a frame-based TDMA/CDMA MAC protocol

摘要

A hybrid of TDMA and CDMA or the so-called time slotted CDMA is a popular mainstream multiple access technique in coordinating resource to accommodate a number of traffic connections/sources. The purpose of this paper is to conduct thorough delay analysis for a specific connection in such a hybrid TDMA/CDMA MAC protocol. The arrival process of this connection is assumed to be the Markov modulated Poisson process (MMPP) and can be generalized to the batch Markov arrival process (BMAP). The service that can be rendered to this connection in time and code is made general to fit any service pattern that one may configure. Past works on the delay analysis of a TDMA system are special cases of this paper. The results obtained in this paper can be used to evaluate the performance of many contemporary quality of service (QoS) oriented frame-based MAC protocols.
