Abstract
A device, method, and non-transitory computer readable medium that determine a reliability level for a communication network. A packet delivery ratio (PDR) is determined for a round period of the communication network operating at an adaptive reliability level based on a packet serial number (PSN). The communication network is controlled in a best effort mode, a reliable mode, or a switching mode based on the PDR.
Claims16
A device comprising:
- processing circuitry configured to
- determine a reliability level for a communication network,
- determine a packet delivery ratio (PDR) for a round period of the communication network operating at reliability level based on a packet serial number (PSN), the round period being a predetermined period for measuring the PDR of sensor data received from the communication network,
- control the communication network to operate in an adaptive reliability mode in response to the reliability level being within a predetermined range, the adaptive reliability mode including a best effort mode, a reliable mode, and a switching mode based on the PDR, wherein the processing circuitry is further configured to
- control operation of the communication network to operate in the best effort mode in response to the PDR being greater than an upper PDR threshold,
- control operation of the communication network to operate in the reliable mode in response to the PDR is less than a lower PDR threshold, and
- control operation of the communication network to operate in the switching mode when transitioning between the best effort mode and the reliable mode, the control including issuing a switch mode message including a modified mode bit in the message header, and
- detect an assurance time interval (ATI) corresponding to a termination of the round period.
