Abstract: The satellite network has the advantages of wide coverage, convenient access, and the influence of the natural environment. Wireless multi-hop network is suitable for the occasion that cannot be easily or inconvenient to lay network facilities and the occasion of the need for rapid automatic networking. Multi-hop network and the satellite network may combine a heterogeneous network that can provide an effective and convenient way to access the network in the ocean or in remote areas. This paper, firstly, builds a heterogeneous network with satellite network and multi-hop network, and discusses the bandwidth delay product (BDP) of heterogeneous network, then proposes a new end-to-end congestion control algorithm. The proposed scheme at the outset increases the dynamic time interval for the initial transmission data that can reduce the backlog of burst data at the access point, and then increases the amount of data transmission in the slow start that can improve high bandwidth delay product of satellite network. In the congestion avoidance, it adjusts the congestion window size by monitoring the random packet loss and congestion packet loss. This algorithm can effectively solve the long delay in heterogeneous networks, and improve the accuracy of the high packet loss rate monitoring in multi hop networks and satellite networks. The proposed algorithm can effectively solve the influence of the long delay in the heterogeneous network, at the same time it can distinguish the different packet loss.
