Heterogeneous Packet Translation for Cross-Technology Communication

Recent advances in cross-technology communication (CTC) enable heterogeneous wireless devices (e.g., WiFi, Zig-Bee, and BLE) operating in the ISM band to communicate and understand each other. However, due to the limitation of standards and devices, existing CTC techniques need to design specific scheme for each heterogeneous wireless pair, which limit the practical applications of CTC. A key insight of this work is that heterogeneous packets could share same semantics but have different pattern features and representations, therefore, we explore the feasibility of packet-level heterogeneous communication translation. We first build a heterogeneous parallel frame dataset for evaluation. Then, we propose HPT, a heterogeneous packet translation approach. A wingman coding mechanism for wireless packet, dual attention module and synchronous interactive decoding method are designed as advanced designs to improve accuracy. Experiments between different translation directions show the proposed HPT achieves high accuracy of heterogeneous wireless packet translation.<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup>
