In this study, a congestion prevention protocol has been developed for WAP traffic with queue management. Developed protocol prevents congestion by creating new queue management for reducing droped TCP packets which has priority. The protocol has been tested using ns-2 (network Simulator-2) simulation tool. In simulation drop-tail, red queue and developed protocol have been implemented in different networks and results have been compared. Obtained results showed that the developed protocol is succesfull for congestion prevention in wireless networks.
