In recent years, visible light communication (VLC), considered as a compelling technology to solve the spectrum problem of traditional radio frequency (RF) communication, has attracted attention in scientific and industrial communities. However, for a variety of reasons, the design of the VLC uplink scheme has become a significantly challenging problem. In this paper, in order to address the preceding problem, we propose a novel decoupled TCP extension protocol for a VLC hybrid network. Different from regular TCP protocol, decoupling operation to TCP transmission in our new protocol can break through TCP’s limitation to a unidirectional link and allow users to fully utilize network resources in a VLC hybrid network consisting of a VLC downlink and a complementary uplink. Furthermore, today most hosts are equipped with several interfaces, so we combine decoupled TCP (DETCP) with multipath TCP (MPTCP) and extend DETCP to a multipath communication situation. Using several links simultaneously ensures more efficient and reliable data transmission in a VLC network. Based on our implementation of the Linux kernel, our experimental results show that our protocol can effectively accomplish the decouple work and achieve high throughput. In addition, several factors that influence the performance are analyzed based on our measurement results.
