A Cross-Layer Design for Video Transmission With TFRC in MANETs

Mobile Ad hoc NETworks (MANETs) are becoming more essential to wireless communications due to growing popularity of mobile devices. However, MANETs do not seem to effectively support multimedia applications and especially video transmission. In this paper, the authors propose a cross-layer design that aims to improve the performance of video transmission using TCP Friendly Rate Control (TFRC). Their design provides priority to video packets and exploits information from the MAC layer in order to improve TFRC's performance. The proposed cross-layer mechanism utilizes Signal to Noise Ratio (SNR) measurements along the routing path, in order to make the route reconstruction procedure more efficient.
