A MAC protocol supporting TCP in DS-CDMA PCNs

A MAC protocol for CDMA PCNs is proposed and studied which is shown to provide a better upper layer performance in the wireless applications. The protocol is based on Preamble Signaling Access which uses a Slotted-ALOHA-like scheme. Markovian chain models are used to analyze the performance of this protocol. Using the modeling, we have provided performance insight comparing the service received by individual user and the whole system under different system configurations. Several performance measures, such as the packet loss, data throughput and data transmission delay are investigated. From the analytical models and simulation results presented in this paper, one can gain interesting insight and useful guidance for incorporating TCP/IP protocol suite into Personal Communication Networks.
