Summary:
Narrowband weak connection network environment is often associated with imperfect network infrastructure. It has the characteristics of low bandwidth, high BER, and unstable connection which can cause high packet loss at the application layer. Narrowband network environment ranges from tens of Kbps to hundreds of Kbps, and the packet loss rate can be more than 50%. Most of the throughput is devoted to retransmit packet so that there is a low effective throughput rate in traditional reliable transmission methods in this environment. In this paper, a reliable effective transmission mechanism is proposed. On the one hand, this mechanism uses multiple heterogeneous networks to transmit data simultaneously to enhance the available bandwidth. On the other hand, redundant encoded packets are generated in each network by RLNC encoder to avoid the increase in transmission delay caused by packet retransmission. It can ensure the reliability of data transmission and maintain a high effective throughput rate in narrowband weak connection environment. Compared with TCP and RUDP, the proposed method can exceed at packet loss rates higher than 20%.
