Abstract

In a real wireless channel, both a channel bit error and a collision between competition stations can cause a data frame loss. Moreover, DCF always assumes that a data frame loss is due to the collision and the contention window will double in next transmission. In fact, we think that the contention window shall be difference between channel bit error and collision. In this paper, we propose a ideal mechanism LD-DCF which can completely differentiate between the two reasons of a data frame loss. An analytical model is given to demonstrate the efficiency of LD-DCF. NS-2 simulation is also used to validate the LD-DCF. By the theoretical and simulation results, the LD-DCF can improve the throughput significantly, especial for the high channel bit error and low contending stations (i.e. the low network traffic).
