Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The adoption of IoT devices is hindered by issues such as lack of standardization, connectivity limitations, power sourcing challenges, and inadequate security measures, particularly due to the short-range nature of wireless technologies like Bluetooth LE, which restricts data transmission and poses security risks.
Innovation Solution
A comprehensive IoT platform is developed, including a standardized hardware/software base, an IoT hub for connectivity, and enhanced security features like secure key exchange and encryption, along with intermediary mobile devices to extend range and facilitate data transfer, ensuring secure communication and data integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication protocols like Bluetooth LE are used for IoT device connectivity, then device portability and ease of connection are improved, but transmission range is limited and security vulnerabilities increase
Solution Approach 1:
The patent introduces a relay device that acts as an intermediary between the IoT device and the hub. The relay device receives data packets from the IoT device and forwards them to the hub, enabling communication beyond the direct wireless range of Bluetooth LE. This mediator approach resolves the contradiction by extending transmission range while maintaining the ease of wireless connection.
2Ease of operation
If wireless communication protocols like Bluetooth LE are used for IoT device connectivity, then device portability and ease of connection are improved, but security measures are inadequate
Solution Approach 1:
The patent implements preliminary security actions by establishing encrypted communication channels and authentication mechanisms before data transmission begins. The system performs security handshakes and key exchanges in advance, ensuring that even though wireless connection is easy to establish, security measures are proactively implemented to protect against vulnerabilities.
3Reliability
If data is transmitted continuously to ensure real-time communication, then data transfer reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic transmission intervals where the IoT device transmits data at scheduled intervals rather than continuously. The system monitors data changes and only transmits when updates occur, combined with periodic heartbeat signals to maintain connection reliability. This periodic approach ensures data transfer reliability while significantly reducing power consumption compared to continuous transmission.
Data Source
AI summary
An apparatus and method are described for modifying packet interval timing to identify a data transfer condition. For example, one embodiment of a system comprises: an Internet of Things (IoT) device comprising a first wireless networking interface to establish communication with an IoT hub over a local wireless network channel, the first wireless networking interface implementing a first advertising interval between advertising packets; advertising interval selection logic to cause the first wireless networking interface to use a second advertising interval for advertising packets upon detecting that the IoT device has data to be transmitted to the IoT hub, the IoT hub to detect that the IoT device has data to be transmitted based on the change to the second advertising interval.
