Gagandeep Kaur, Tanu Preet Singh . A Weighted Fair Queue based SBPN (WFQ-SBPN) Algorithm to Improve Qos for Multimedia Application in Mobile Ad Hoc Networks. International Journal of Computer Applications. 112, 2 ( February 2015), 13-17. DOI=10.5120/19637-1214
Abstract
In this paper we investigate a new technique based on SBPN for congestion avoidance. In this technique we 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 its 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. The study has carried on some issues like throughput, packet delivery ratio (PDF), packet drop. Simulation has been performed using NS-2. 34. The simulation results show that our proposed algorithm will present better network performance in throughput, packet delivery fraction and number of dropped packets.
