What This Document Is
This is a detailed exploration of Medium Access Control (MAC) layer fair sharing techniques within the context of wireless ad hoc networks. Specifically, it investigates the performance of different MAC protocols – including CSMA, FAMA, and the widely adopted IEEE 802.11 standard – when used in conjunction with TCP. The material delves into how these protocols behave under various network conditions and topologies, offering a comparative analysis of their strengths and weaknesses. It’s based on research conducted at the University of California, Los Angeles.
