A novel routing algorithm over the multipath networks

Internet continues to suffer from limited bandwidth, highly varying delay, and losses. In literature, several studies suggested that an application can increase its aggregate throughput, and reduce its end-to-end delay and losses, by distributing data over multiple paths. In this work, a novel routing algorithm based on prediction method and optimization theory is proposed for improving the quality of service over the multipath network. The paper describes how the algorithm dynamically predicts loss levels over all available network paths and adjusts the traffic allocation proportion of packets for next prediction period by the PSOSA. 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.
