In this paper, the authors investigate a new technique based on SBPN for congestion avoidance. In this technique, they proposed a new algorithm based on WFQ for improving the QoS for multimedia traffic in MANET. In traditional algorithm used SBPN-FIFO in which data transmitted in which order it's received. In SBPN-FIFO all packets are treated equally by placed into single queue that's why short packets have to wait long time. In proposed algorithm SBPN-WFQ where data handle with priority and every flow have opportunity to send data in specific time. This method reorders or discard packet according to expiry time. The main advantage of SBPN-WFQ it only drops packets only of aggressive flow.
