Optimization of Hybrid Token-CDMA MAC System Using Cross-Layer Information

Overview

This paper presents a joint Medium Access Control and PHYsical (MAC-PHY) layers solution for optimizing the system performance in the hybrid Token-CDMA MAC system. The proposed scheme is designed in order to provide continuous monitoring of the performance achieved by the users and adjusting transmission parameters using different spreading factors. Various performance metrics are used to demonstrate effectiveness of the cross-layer interaction for the hybrid Token-CDMA MAC protocol.
