Telegram splitting transmission method for bidirectional networks

A method for operating a transmitter of a wireless sensor network, wherein the wireless sensor network comprises a base station and a plurality of sensor nodes, wherein the transmitter is the base station or one of the plurality of sensor nodes, wherein the method comprises:

• generating at least three transmission data packets by splitting a first data packet destined for a first data receiver into the at least three transmission data packets, wherein each of the at least three transmission data packets is shorter than the first data packets, wherein, when generating the at least three transmission data packets, the at least three transmission data packets are channel-encoded such that only a portion of the transmission data packets is required for decoding the first data packet;
• transmitting the at least three transmission data packets in a frequency channel via a communications channel with a time gap;
• monitoring the frequency channel in order to recognize an interference or transmission of a further data transmitter in the frequency channel;
• wherein the transmission element for transmitting data packets is configured not to transmit, transmit only partly or at a later time via the communications channel a transmission data packet, waiting for transmission, of the at least three transmission data packets if an interference or transmission from a further data transmitter is recognized by the monitor element for monitoring the frequency channel at the time of transmitting the transmission data packet;
• wherein, when transmitting the at least three transmission data packets, a transmission data packet, waiting for transmission, of the at least three transmission data packets is not transmitted, transmitted only partly or at a later time if an interference or transmission from a further data transmitter is recognized by monitoring the frequency channel at the time of transmitting the transmission data packet.

A non-transitory digital storage medium having stored thereon a computer program for performing a method for operating a transmitter of a wireless sensor network, wherein wireless sensor network comprises a base station and a plurality of sensor nodes, wherein the transmitter is the base station or one of the plurality of sensor nodes, wherein the method comprises:

• generating at least three transmission data packets by splitting a first data packet destined for a first data receiver into the at least three transmission data packets, wherein each of the at least three transmission data packets is shorter than the first data packets, wherein, when generating the at least three transmission data packets, the at least three transmission data packets are channel-encoded such that only a portion of the transmission data packets is required for decoding the first data packet;
• transmitting the at least three transmission data packets in a frequency channel via a communications channel with a time gap;
• monitoring the frequency channel in order to recognize an interference or transmission of a further data transmitter in the frequency channel;
• wherein the transmission element for transmitting data packets is configured not to transmit, transmit only partly or at a later time via the communications channel a transmission data packet, waiting for transmission, of the at least three transmission data packets if an interference or transmission from a further data transmitter is recognized by the monitor element for monitoring the frequency channel at the time of transmitting the transmission data packet;
• wherein, when transmitting the at least three transmission data packets, a transmission data packet, waiting for transmission, of the at least three transmission data packets is not transmitted, transmitted only partly or at a later time if an interference or transmission from a further data transmitter is recognized by monitoring the frequency channel at the time of transmitting the transmission data packet,
• when said computer program is run by a computer.
