DCCP, or Datagram Congestion Control algorithm, is a transit layer algorithm that ensures dependable data transfer despite the presence of unstable connections. DCCP includes a congestion management device that modifies the packet transmission rate based on the status of the network. When it comes to bottleneck losses and cellular connection failures, however, DCCP does not make any distinctions. caused by fading, which causes extra rate changes. In this article, we suggested a method to improve DCCP's usage of available capacity in a cellular network. We used a cross-layer loss separation method to split out the effects of crowding loss from those of fading. The true fading loss rate can be inferred thanks to the cross-layer based method that identifies frame loss in the data connection layer in real-time. After that is done, the transit layer packet loss will not include the fading loss. Once the originator has determined the congestion loss rate accurately, they can use the DCCP rate control process to make transmission rate adjustments that are reflective of the actual congestion condition along the transmission route. Our simulation findings indicate that when the fading loss rate in a wireless network ranges from 5% to 15%, DCCP with our suggested CCID 3 rate control algorithm can detect fading loss and increase transmission rates by between 4.7% and 15.5%.
