Abstract :
This research aims to improve the quality of MPEG-4 video transmission over MANET using cross layer paradigm that transfer the MPEG-4 video priority information from application to medium access control (MAC) layer. This information is used by proposed adopting dynamic mapping algorithm (ADMA) along with other information as access category (AC) congestion from MAC and hop count to destination from network layer to map the video frames in proper ACs. The proposed ADMA is compared with the existing Enhanced Distributed Channel Access (EDCA) and static mapping approaches based on Peak Signal-to-Noise Ratio (PSNR), Throughput and Average end-to-end delay evaluation parameters.
