Abstract

Problem statement: As the Variable Bit Rate (VBR) is high in MPEG, the video experienced long delay and unexpected data loss. In wireless channel, due to noise and interference of other signals transmission rate cannot be predicted. Approach: In this paper we proposed an intelligent fuzzy logic controller for transmission of Moving Picture Expert Group (MPEG-4) video signals over wireless channel. A Nero-Fuzzy (NF) controller was used to control the output rate of the buffer so that the signals were transmitted smoothly to wireless channel. Results: Simulation results showed that the use of intelligent fuzzy logic and nero-fuzzy controller improved the data transmission rate and decreased long delay when compared with other conventional methods. Conclusion: We proposed an intelligent fuzzy logic controller which adjusts the transmission rate dynamically so that the transmission loss and delay could be minimized. The traffic shaping buffer is used to prevent excess back-to-back transmission of video signals.
