Paper Abstract

In this paper, we review the characteristics of a diffuse infrared channel and create a simulation environment for a diffuse infrared wireless network study in the network simulator ns-2. To investigate the performance of Distributed Coordination Function (DFC) access method in IEEE802.11 MAC protocol based on the Diffuse infrared (DFIR) physical layer, we focus on the key mechanisms, RTS/CTS message exchange and backoff algorithm, and evaluate the protocol performance for various network configurations. Our simulations show that the value of RTS_Threshold strongly depends on the network configuration. We also investigate the trade-off between RTS/CTS and backoff schemes. The results are shown in throughput and average MAC delay.
