Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If physical nodes with high functionality are used for M2M communication, then communication capability is improved, but security vulnerability increases
Solution Approach 1:
The patent creates virtual copies of physical nodes (virtual nodes) that replicate the communication functionality while isolating the actual physical devices. These virtual nodes serve as intermediaries that handle M2M communication protocols and data processing, allowing the physical nodes to maintain high functionality without directly exposing security vulnerabilities. The virtualization layer acts as a buffer that preserves communication capability while reducing security risks.
Solution Approach 2:
The patent introduces virtual nodes as intermediary entities between the physical M2M devices and the network infrastructure. These virtual nodes perform functions such as authentication, data formatting, and protocol conversion, thereby protecting the physical nodes from direct security threats while maintaining full communication functionality. The intermediary layer handles security-critical operations separately from the physical device logic.
2Reliability
If virtual nodes are implemented as software modules, then security is improved, but system complexity increases
Solution Approach 1:
The patent designs virtual nodes with multi-functional capabilities that consolidate multiple security and communication functions into single software modules. Each virtual node can simultaneously handle authentication, data processing, protocol conversion, and device management tasks. This universal approach reduces the overall number of separate components needed, thereby managing system complexity while maintaining comprehensive security functionality.
3Ease of repair
If physical nodes and sinks are virtualized, then maintenance is simplified, but communication overhead increases
Solution Approach 1:
The patent merges multiple virtual node instances that share common functionality into consolidated virtualization environments. By combining several virtual nodes that perform similar M2M communication tasks into shared infrastructure, the system reduces redundant communication protocols and data transmissions. This consolidation maintains ease of maintenance through centralized management while minimizing the communication overhead that would otherwise result from separate virtualized instances.
Data Source
AI summary
An information processing method of the present disclosure is a method in which an information processing device executes an M2M application for performing M2M communication with a physical node. The information processing method includes communicating with at least one of a virtual node and a virtual point by the information processing device. The virtual node is a node in which at least one of a function of the physical node that is a communication partner of M2M communication and a function of reinforcing the physical node is implemented as a software module. The virtual point is a point in which a function of a physical sink that performs wireless communication with the physical node, a function of reinforcing the physical sink, and an installation place of the physical sink are implemented as software modules.
