Analysis of a multiple service MAC layer for two-way two-layer LMDS networks

摘要

Local Multipoint Distribution Service is a solution to the "last mile problem" for broadband digital service access systems. A two-layer cellular network architecture can be used to increase signal coverage. In such networks, a Multiple Access Control (MAC) protcol is needed to manage the two-way communications between LMDS providers and their users. A novel MAC layer has been proposed for use in the EU/ACTS project CABSINET. However, the MAC layer should also be able to bear multiple service classes in order to support future users with a range of applications such as voice and Internet access, as well as the video services. This paper presents an analysis of the CABSINET MAC layer performance when considered for use with multiple traffic types.
