Abstract

The invention provides a cross-protocol communication method and system from a WiFi device to a ZigBee device. The method comprises the steps that a WiFi sending end generates the to-be-sent symbol-level energy modulation bit information bearing the WiFi data bits and the cross-protocol data bits transmitted to the ZigBee device simultaneously, wherein the cross-protocol bits are obtained based onthe symbol-level energy modulation; a ZigBee receiving end processes the received signal strength indication sample information and starts a cross-protocol communication receiving process to obtain the cross-protocol data bits needing to be received; and meanwhile, the WiFi receiving end obtains the symbol-level energy modulation bit information through a standard WiFi receiving process, and thenstarts a WiFi data recovery process to obtain the original WiFi data bits. According to the method and the system provided by the invention, the cross-protocol communication is realized through the code element level energy modulation, and the method and the system can be compatible with an existing commercial network at the aspects of a used channel, a physical layer and an MAC layer.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and system for cross-protocol communication from a WiFi device to a ZigBee device. Background technique [0002] Due to the realistic scene requirements of heterogeneous node communication in the Internet of Things, and this communication can be used to transfer coordination information to achieve more efficient heterogeneous network coexistence, cross-protocol communication has become a research hotspot in recent years. Related studies mainly adopt two technical solutions: signal simulation and packet-level energy modulation. [0003] Signal simulation allows wireless nodes to simulate the transmission signals of heterogeneous nodes, so that receiving nodes can demodulate information through normal processes. For example, WEBee modifies the payload of WiFi data so that the signal it sends is a legal ZigBee signal, so as to realize the communication from WiFi to Z...
