A frame structure for navigation and protection systems (NPS) in IoT networks that uses distributed IoT devices with guard time and time slots to transmit and receive information without interference, employing Ethernet packet protocols, IP packet protocols, and IEEE1588 precision time protocol for synchronization, enabling efficient data collection and processing in smart environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If distributed IoT devices transmit data simultaneously in 5G networks, then data collection efficiency is improved, but signal interference and collision increase
Solution Approach 1:
The patent segments the transmission medium by introducing frame structures with time slots that divide transmission opportunities into discrete units. Devices are assigned specific time slots within frames to transmit data, preventing simultaneous transmissions and eliminating signal collision while maintaining efficient data collection across distributed IoT devices in 5G networks.
2Reliability
If guard time is added to frame structure, then signal collision is prevented, but transmission time is increased
Solution Approach 1:
The patent implements periodic frame structures where guard times are regularly inserted between time slots in a cyclic manner. This periodic arrangement ensures collision-free transmission by systematically preventing signal overlap, while the structured repetition allows devices to predict transmission opportunities and optimize their data buffering and transmission timing.
