A novel forwarding algorithm over multipath network

Abstract

In this work, a novel data forwarding algorithm based on prediction method and optimization theory is proposed for improving the quality of service (QoS) in real-time applications over the wire network. The proposed prediction method is based on the time-series models of observed trends over all available network paths at each predetermined time. This predictive information is then used as an input for the forwarding decision. The forwarding algorithm is meant to minimize the packet loss rate by adjusting the forwarding rate of packets over each path for next prediction period by the PSO (particle swarm optimization). A number of experiments are performed. The proposed algorithm makes the most promising data forwarding method with an effective network performance, even under unfavorable scenarios.
