- Improving TCP Performance Over Mobile Wireless Environments Using Cross Layer Feedback
- Transmission Control Protocol TCP is known to suffer from performance degradation in mobile wireless environments. This is because such environments are prone to packet losses due to high bit error rates and mobility induced disconnections. TCP interprets packet losses as an indication of congestion and inappropriately invokes congestion control mechanisms,...
