Abstract

The interaction between transport layer and MAC layer is very complex. Yet, understanding this relation is essential for devising an efficient protocol that maximizes the network throughput in a fair manner and minimizes the access delay. The effort in this paper focuses on examining all possible interference modes arising among two interfering Bi-directional traffic like TCP for one-hop connections under a Two-Disc model of interference. We believe that this work is the first in the literature that analyzes the TCP similar traffic flows under all these possible link interactions. Using ns-2, we run extensive simulation experiments for all possible link configurations. The results identify several performance groups. In particular, we are able to identify which configurations will lead to unfairness problem.
