A concurrent multi-path transmission of data allocation algorithm based on heterogeneous networks

The reasons for the decline of the concurrent multipath transfer in the heterogeneous networks are analyzed in this paper and a data distribution algorithm which is applicable to the heterogeneous networks is proposed. The Kalman filter algorithm is used to assess the propagation delay, so that the uncontrolled propagation delay can be predicted in the heterogeneous network. After the path sending a data, the transmission delay of this path updated immediately, and finally the path of least total delay is chosen to transfer data. Simulation results show that, compared with the default round robin algorithm and the transmission delay prediction based data allocation scheme for CMT, the algorithm which is proposed in this paper is better in total delay, the value of free receive buffer and the overall throughput.
