A Novel Cross-Layer Architecture for Video Streaming Over MANET

摘要

Video streaming is one of the prominent applications of Mobile Ad Hoc Network. Due to high rate requirements, less resource, and severe delay constraints, maintaining real-time media traffic such as audio and video in presence of dynamic network topology is difficult. To cope with this, we propose a cross-layer design (CLD) to optimize the overall performance of video streaming services over MANET. Our CLD jointly controls the video trans-mission rate, delay constraint, congestion, and resource constraint in order to maximize the received video quality and the performance of the network. When compared with conventional techniques in MANET, our algorithm results in average end-to-end delay, average energy consumption, and the packet loss is considerably reduced with increase in high throughput and good delivery ratio.
